SHT-10 Mesh-protected Weather-proof Temperature/Humidity Sensor
Take your next outdoor sensor project to the next level with an SHT-10 based temperature/humidity sensor. The sensor includes a dual-use sensor module from Sensirion in a sintered metal mesh encasing. The casing is weatherproof and deters water from seeping into the body of the sensor and damaging it, but allows air to pass through so that it can measure the humidity outside. Submersible in water, it's always best to avoid long-term (over 1 hour at a time) submersion, and it obviously would only give you temperature readings.
Humidity readings have 4.5% precision; the temperature is 0.5% precision. A microcontroller is required to interface. The sensor is not washed after reflow and rehydrated according to datasheet requirements.
The sensor is essentially just a Sensirion SHT-10 with the 4 data/power wires brought out, so any SHT-1X code for a microcontroller. The sensor works with 3 or 5V logic. The 1-meter long cable has four wires. Old version with four color wires: Red = VCC (3-5VDC), Black or Green = Ground, Yellow = Clock, Blue = Data
Newer version with four color wires: Red = VCC (3-5VDC), Black = Ground, Yellow = Clock, Green = Data
For Arduino, there's a handy Sensiron library with an example. For Propeller, there's an SHT1X sensor object. Don't forget to connect a 10K resistor from the Data line to VCC.
