Take your gardening project to the next level with a SHT-10 based soil sensor. The sensor includes a temperature/humidity sensor module from Sensiron in a sinter metal mesh encasing. The casing is weatherproof and will keep water from seeping into the body of the sensor and damaging itbut allows air to pass through so that it can measure the humidity (moisture) of the soil. It is designed to be submersible in waterbut it\'s always best to avoid long-term (over 1 hour at a time) submersionif 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% precisiontemperature 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 = GroundYellow = ClockBlue = Data.Don\'t forget to connect a 10K resistor from the blue Data line to VCC.
For Arduinothere\'s a handy Sensiron library with example. For Propellerthere\'s an SHT1X sensor object
