Review on 🌡️ Inkbird Humidity Controller Probe: Enhance Your IHC200 Humidistat Sensor Efficiency by David Hodgson

I bought this to replace the humidity sensor on my Inkbird IHC-200. The old sensor stopped working after getting wet. The old sensor had 3 wires: black, white and red. The new sensor also has a fourth blue wire. I have tried leaving the blue wire unconnected and connecting to each of the other three wires. No matter what I tried, the device would emit a constant beep and the screen would say "Er" in the event of an error. The Inkbird IHC-200 itself is a good product, just don't get the sensor wet. The Inkbird IHC-200 could be improved if it had a pluggable humidity sensor like the Inkbird ITC-608T.
