Soil Temperature/Moisture Sensor - SHT10

16.250 KD

It is designed to be submersible in water, but it's always best to avoid long-term (over 1 hour at a time) submersion, if you need something that can be submerged for over an hour you may want to find a different sensor. It can also be simply placed outside for exterior weather sensing.

Humidity readings have 4.5% precision, temperature is 0.5% precision. A microcontroller is required to interface. The sensor is not washed after reflow and is rehydrated according to datasheet requirements.

The sensor is essentially just a Sensiron SHT-10 with the 4 data/power wires brought out so any SHT-1X code for a microcontroller will work. The sensor works with 3 or 5V logic. The 1 meter long cable has four wires: Red = VCC (3-5VDC), Black or Green = Ground, Yellow = Clock, Blue = Data. For Arduino, there's a handy Sensiron library with example. For Propeller, there's an SHT1X sensor object. Don't forget to connect a 10K resistor from the blue Data line to VCC.
