Check your wiring, the Meter group CTD sensor has a red wire for the data (signal) wire, white is positive voltage, and black is ground. It’s kind of backwards from most common DC sensor wires
Check your wiring, the Meter group CTD sensor has a red wire for the data (signal) wire, white is positive voltage, and black is ground. It’s kind of backwards from most common DC sensor wires where red is usually the voltage supply wire. I’ve confirmed with the folks at Meter that the sensor works just fine at 3.3v.
