Mesh-protected Weather-proof Temperature/Humidity Sensor

Take your next ourdoor sensor project to the next level with a SHT-10 based temperature/humidity sensor. The sensor includes a dual-use sensor module from Sensiron in a sintered metal mesh encasing. The casing is weatherproof and will keep 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. While it is designed to be 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. For that, our metal-cased temperature sensors would be better! This sensor is best for simply placing 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.
