I have some apogee pyranometers and pyrgeometers for my monitoring stations, and each of these sensors has an internal heater that helps to clean off snow, rain, and frost. The heaters operate at 12 volts, so I have them connected directly to my 12-volt battery which powers my entire setup. Having the heaters connected 24/7 draws a lot of power relative to the other sensors and instrumentation I am using, which quickly drains my batteries. I would like to move to a less frequent logging interval (going from every 15 minutes to every 60 minutes), and I would like to potentially power the heaters on my sensors for less time, for example for the 15 minutes leading up to my new logging time (on the hour). Because these heaters need a 12-volt supply, my understanding is that using a power relay could be an appropriate tool for controlling these heaters with a signal from the Mayfly while still having their power source come directly from the battery.

There are quite a few relays out there, and I’ve seen some previous discussion posts with references to Seeed’s website (https://wiki.seeedstudio.com/Seeed_Relay_Page/). I’ve also seen lots of relays on Adafruit, such as the following which seems like a good option from my limited knowledge in this area: https://www.adafruit.com/product/2923. I wanted to run this by the EnviroDIY community to get some input or suggestions. Also, from what I’ve read, it seems like a latched relay will help me save on power, which is really important for this implementation, and the Adafruit example has that option as well.
