Hemanth Narayan Dakshinamurthy started the topic Bypassing SDI-12 library to read 8-bits by using high volume binary command in the forum Other Data Loggers 1 year ago
I’m working with soil moisture sensors and currently using the Acclima TDR-305N, which communicates via the SDI-12 protocol. I’ve successfully interfaced with the sensor using the Arduino SDI-12 library and can retrieve standard measurements without issue.
However, I’m now trying to access the actual TDR waveform using the High Volume Binary Com…[Read more]

Wow looks fascinating. While the SWaP-C mechanical looks so nice, and it’s the open-source software on opensource readable hardware that can make it so nicely extensible. It’s great to see the Stonefly’s SAMD5 […]

Shannon Hicks replied to the topic MayFly Pin On/Off Communication in the forum Mayfly Data Logger 1 year, 1 month ago
What is the control board that you’re using between the Mayfly and the pumps? Something with some relays? How is it connected to the Mayfly? Via Grove cables or the 2×10 header pins? Can you post some photos of the setup, or maybe a wiring diagram?
Kiersten started the topic MayFly Pin On/Off Communication in the forum Mayfly Data Logger 1 year, 1 month 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.
I have my hardware system set up, and I have checked the voltages and battery and pins throughout the system, with reason to believe that my problem is not because of any wiring.…[Read more]
