Sensors / Feed

Want to talk about sensors that don't quite fit into any of our tech-specific groups? This is the place to post! From temperature and humidity to airflow and pressure sensors, there are many environmental sensing tools that can add valuable data to core conservation monitoring technologies. With the increasing availability of low-cost, open-source options, we've seen growing interest in integrating these kinds of low bandwidth sensors into existing tools. What kinds of sensors are you working with?

Hi Patrick, 

This is so cool, thanks for sharing! It's also a perfect example of what we were hoping to capture in the R&D section of the inventory - I've created a new entry for #CollarID so it's discoverable and so we can track how it evolves across any mentions in different posts/discussions that come up on WILDLABS. This thread appears on the listing, and I'll make you three the contacts for it too. But please do go in and update any of the info there as well!

Thanks @Freaklabs, I think you'll really enjoy getting involved with this too as we're looking for input from makers in the community to get the most from the approach and to capture features and usability ideas from a large number of people.

I've a new modular drop-off tag build using @Rob_Appleby's original SensorDrop board that I think would be great for this project too to see if we can drop different compartments, or do various different timed events with the one TimeLord board.

Most importantly, we have to make it play a MIDI version of the DoctorWho theme song when you arm the device. That has to be the #1 feature if you ask me!

Hi @Henrikcox this is very exciting news about the Sentinel. The LoRa and cell options sound really great for a lot of urban/semi-urban areas, so a big potential winner there. Does the Sentinel offer any sort of GPIO pins that could possibly be connected to something external (e.g. like a sound unit that can playback scary sounds) if a detection occurs? 

Also @StephODonnell I'd be super keen for something like a 'WILDLABS working group' or similar on this, as it such an important topic. 


Hi @Henrikcox 

I hope you are well. 

I am not sure if you may remember myself and my colleague from CLS. We had a meeting and met in-person at Earthranger last year. 

I would be very keen to discuss your current satellite limitations and suggest options based on your required outcome. Please let me know if I can assist?

A Sensor-Based Approach to Studying Animal Behavior in Light Pollution Research

Greetings, I'm Sebastian!I am share with you a project that I will need help on some aspects: "Development of a system for recording animal activity and behavior based on sensors...

4 0

Thanks for helping me!

For now, I'll be testing with mains power (220V). The final prototype needs to be functional using solar panel. 

The main system will be a Raspberry Pi, as the Brain of this project, receiving and storage all the measurements from the other devices, controlling the system. The measurement devices will be a microcontroller (still searching for which one to use) with differents sensor, such Lux sensor like TSL2561 or 2591, AudioMoth to record animals sounds, temperature and some other measurements.

For synchronization, must be effective, because the measurements must be or have the same time, so the storage data from differents devices can be grouped by it's timestamp and have full control for animals and fauna. So, probably it will be a lot of data per day.


The distance between each devices I haven't study yet, consider 20 meters within each device.

Unless you are planning on making a mesh network between nodes then the total distance spanning the location of all the nodes is important to know, not just the intra node distance.

If you have a Raspberry Pi as a main master node then you could install my sbts-aru project as a base project and you would get a sub-microsecond master time base by default as well as the GPS synchronizes the main system time with typically less than 0.1 microsecond, and SD card corruption resilience due to the in-memory overlayFS architecture.

If the total distance was 20m across all nodes, then the approach above could also combined the audio gathering capability as the sbts-aru project does audio logging as it would be within 20m of an audiomoth anyway, then you also have time-synchonized audio. If the distance is spanning 100m for example and it's just the intranode distance that is 20m then everything is somewhat different with respect to synchronization.

Hi Krasi! Greetings from Brazil!

That's a cool journey you've started! Congratulations. And I felt like theSearchLife resonates with the work I'm involved round here. In a nutshell, I live at the heart of the largest remaining of Atlantic forest in the planet - one of the most biodiverse biomes that exist. The subregion where I live is named after and bathed by the "Rio Sagrado" (Sacred River), a magnificent water body with a very rich cultural significance to the region (it has served as a safe zone for fleeing slaves). Well, the river and the entire bioregion is currently under the threat of a truly devastating railroad project which, to say the least is planned to cut through over 100 water springs! 

In face of that the local community (myself included) has been mobilizing to raise awareness of the issue and hopefully stop this madness (fueled by strong international forces). One of the ways we've been fighting this is through the seeking of the recognition of the sacred river as an entity of legal rights, who can manifest itself in court, against such threats. And to illustrate what this would look like, I've been developing this AI (LLM) powered avatar for the river, which could maybe serve as its human-relatable voice. An existing prototype of such avatar is available here. It has been fine-tuned with over 20 scientific papers on the Sacred River watershed.

And right now myself and other are mobilizing to manifest the conditions/resources to develop a next version of the avatar, which would include remote sensing capacities so the avatar is directly connected to the river and can possibly write full scientific reports on its physical properties (i.e. water quality) and the surrounding biodiversity. In fact, myself and 3 other members of the WildLabs community have just applied to the WildLabs Grant program in order to accomplish that. Hopefully the results are positive.

Finally, it's worth mentioning that our mobilization around providing an expression medium for the river has been multimodal, including the creation of a shortfilm based on theatrical mobilizations we did during a fest dedicated to the river and its surrounding more-than-human communities. You can check that out here:


Let's chat if any of that catches your interest!


Hi Danilo. you seem very passionate about this initiative which is a good start.
It is an interesting coincidence that I am starting another project for the coral reefs in the Philipines which also requires water analytics so I can probably work on both projects at the same time.

Let's that have a call and discuss, will send you a pm with my contact details

There is a tech glitch and I don't get email notifications from here.

Power managment/Recharging System and Communication System

Power usage for microcontrollers with solar is  much more manageable. For Raspberry Pi's and higher it gets expensive and big.

I'm quite impressed by the specs from the Goal Zero Yeti devices. This can have high capacity and be charged with Solar. Not small though. And the price is not in proportion to the Pi's.

So this 200x model for example, would be close to 16 days running the audio recorder. Let's say 10. without solar. Add solar? Depends on the size of the panels I guess. Power usage for mobile networking? Depends on how much you transmit.

Probably some well documented experiments would be really nice for people here. Sounds like something nice for the next set of grants :)

How are Outdoor Fire Detection Systems Adapted for Small Forest Areas, Considering the Predominance of Indoor Fire Detectors?

How are fire detection mechanisms tailored for outdoor environments, particularly in small forest areas, given that most fire and smoke detectors are designed for indoor use?

1 0

Fire detection is a sort of broad idea.  Usually people detect the products of fire, and most often this is smoke.

Many home fire detectors in the US use a radioactive source and measure the absorption of the radiation by the air.  More smoke means more absorption.

For outdoor fire detection, PM2.5 can be a very good smoke proxy, and outdoor PM2.5 sensing is pretty accessible.

This one is very popular in my area.

This is a really late answer but I was new to wildlabs then. I have a security appliance that uses state of the AI models and user defined polygon areas of interest that generates video alerts of intrusions in typically under a second.

Although its setup to install automatically on an NVidia AI on the edge boxes of your intentions were to monitor a great deal of cameras you could also install it on a desktop with a high end GPU for very high performance. At home I use a desktop with an rtx 2080ti and monitor around 15 cameras and a thermal imaging camera (old one).

I have also tested a high end model (yolov7) on a high end thermal imaging camera image and it works fine as well.

Thermal yolov7

Thermal imaging cameras are hellishly expensive though and I’ve found that new extremely light sensitive cameras like the HIKvision colorvu series almost obsoletes them in terms of people detection at night at a fraction of the cost.

If you are interested I’d be happy to show you a demo in a video meeting sometime if you like. I’m pretty sure it would meeting all your intrusion detection and alerting needs.

Autonomizing Small Mammal Traps

One thing to keep in mind is that researchers often want or at least would like to get certain metadata on the tagged animals like sex, size, weight, apperent fitness etc. Without these the questions you can ask can get rather limited. Also, it will also often be highly desired to take samples like blood, hair, other tissue e.g.

In addition, there can be cases where it may be better not to tag the animal if it is not the right age group, is too small to carry the tag, seems like it is not in a good shape etc.

I think it will take quite an effort to get automated systems (capture robots) to make these decisions to a degree you can trust.



I always thought a tracker that attached like a slap bracelet would be sweet.

While pretty expensive, everyone I know has had good experiences with the HOBO weather stations and can be customizable if needed. Would still be my rec if you need something ASAP 

Hi Carly, thanks for this. I forgot to mention HOBO in my original post, but I had them down as the main available option. Think it might have to be them, I'll have to check for $ down the back of the sofa...

I came across this which looks like it might work for you.

Others have mentioned Davis.  I used the Davis vantage pro2 in a previous life, and the cabled version was about USD200 IIRC. However, it must operate with a display console, which can take an optional data logger, but the console is intended to be kept indoors.  This means providing a weatherproof enclosure for it in the forest, in addition to a mast for the anemometer etc.
