Review on XY-MD02 Temperature Humidity Transmitter Module with SHT20 Sensor - High-Performance Temperature Humidity Sensor Module by Jason Tinnen

Revainrating 1 out of 5

Poor accuracy makes it useless

Would like to like this device. Well put together and Modbus works as advertised. Unfortunately it doesn't seem to be calibrated. Humidity 25%, actually 43%. Read 98 F (37 C) when actually 73. Bought 2 of these and haven't tracked reality or each other. They offer a calibration register to set +/- 10°C and +/- 10% humidity, but this is not enough to correct the error and with an error that large, don't trust that Device provides calibrated readings.

Pros
  • Accessories
Cons
  • Good but not great
