Welcome to the group, @divyar !  Can you please tell us a little more about yourself and your interests in this thread?  Thanks!

Hi all!  I hope everyon had a restful break.  We have a couple new members to the group!  @dalenerusso and @ediminin can you please introduce yourselves here?

Hello All,

My name is Karima Cherif and I work for WildAid Marine and our focus is to end wildlife trafficking in our lifetime. I specialize in marine electronics and work in Gabon, Galapagos, Tanzania, and the Bahamas. In Gabon, we have many small scale fishing canoes that transport illegal bush meat such as pangolin and shark fin. Especially, with COVID the trafficking is increasing as people are becoming more despair to feed their families and cover their basic expenses. I append an article from NBC that discussing a new app that we developed in 2020 called O-Fish (Officer's Fisheries Information Sharing Hub). It is free and we invite MPA managers and agencies to try it.

Hi Akiba,
Yes, the TSL2591 has an interrupt pin and there are also a couple of example applications in the Adafruit and TSL2591MI libraries. I am doing tests making the connections with Dupont cables in the I2C connector of the Wildlogger, and for the interruption I will use the corresponding pin of the PIR connector
The connections do not concern me since, once the prototype has been tested and defined, my idea would be to make the maximum of welded connections to avoid failures
I'm still in the design phase, I already have the hardware quite defined, and now I have to enter with the most difficult part, the software, which for me is where I have the most difficulty
I have been gathering the elements to prepare the cake, and now is the time to enter the kitchen, I will not deny that I am excited and terrified at the same time
I'm already telling you ...
Regards !

I appreciate your encouragement !

Don't hesitate that I will keep you informed of the progress that I am making

Happy weekend !

Hi @Alex.L , I would suggest the same as for @mattzig at https://www.wildlabs.net/community/thread/1046#post-4348 :

I could try to connect you with some of the people and orgs we have worked with. If you go through https://www.vizzuality.com/project/ and identify the projects you would like to be look into, I can then try to connect you with the best person for each project.

And I would be very interested in learning more about your research group's work, besides your current research question, if possible!

Happy New Year! Luisa

Hi Akiba,
Oh, your answer is great!
My idea is to build a DL that allows,

• Light registration, with time stamp, when it exceeds a certain threshold (To control the human presence in the cave) The card only has to record when this threshold is exceeded to save energy
• Periodic record of temperature and humidity
• Data recording on SD
• Autonomy of at least 4 months

I have tried some sensors and I think I will use the TSL2591 because it has a very low detection threshold (0.18 uLux) and has an interrupt pin. I've already been testing some sample libraries, and I think it would be ideal
For temperature and humidity I am hesitating between using the DHT11 or the BME280
Perfect the external reference of the ADC if it serves to have more accurate readings
My idea is to use a power bank with 3 or 4 18650 Lipo batteries and built-in BCP, and to be able to disconnect the device when it detects that the power supply is less than 3.2V
Is the Sandisk card you mention a normal one, or of an industrial type like the one you presented in the corresponding module?
My best wishes,

Oh that sounds like a fascinating application. I've actually just started a thread for Wildlogger add-on board requests. The TSL25911 sounds do-able and also it looks like one useful thing would be to put together some adapter cables to other popular modular systems like the Adafruit Stemma and Seeed Grove. Let's discuss this in the other thread. 

Hi JAL.

For Module 3.4 - Lab 4a, the time will be hard coded into the sketch and then it will just print that time out. It's just to demonstrate how you would set it and how you would print it out. Every time you reset the board, the same time is reprogrammed into the real time clock so it will never advance. 

Where you will see the actual real time clock behavior is in Module 3.4 - Lab 4b where you set the clock from the command line and can read it from the command line. Since it won't be hard coded but rather set at run-time, and then independently read out, you should see the clock advance. Also you should only need to set the clock once as long as the backup battery holds up (should be good for a few months to years). 

Please try lab 4b and check if the clock can advance. You should see the seconds incrementing at least.

Hi Akiba!
Now it's okay, and the clock is ticking!
Now I understand the errors I made, I had used the example of the Rtc_Pcf8563 "Setclock" library that contains in the Setup an "rtc.initclock" statement, with which every time you restart the program the clock starts counting from the starting point of departure.
Your first example did not set the clock either, and it only served to enter a time and print it later.
I had also tried to use the Rtc by Makuna library to automatically synchronize the time of the PC with that of the RTC, but I got a time loss error, as if, for some reason, the RTC did not retain the time. It is true that this library is designed for other RTC models of the DS **** series, and surely the error comes for that reason
Do you know if there is a library to fulfill this function with your RTC?
Thank you !!
