Kiersten started the topic MayFly Pin On/Off Communication in the forum Mayfly Data Logger 7 months ago
I am using a MayFly to control pumps in a water sampler to pump water for specified timeframes. I have the battery powering the pumps and a converter to power the board.

Hello,
Our group ordered the Digi Xbee 3 Global Modems (XB3-C-GM2-UT-001) to connect to our Mayfly boards. We have a combination of 0.5b and 1.1 boards that we use in the field. I have been using a 1.1 board to perform tests on the new modems but I have not had any success uploading the data to Monitor My Watershed. I have attached the sketch I…[Read more]
