Humidity and Temperature Sensor Module
We have ✅ 8 available of the FT-HUMID in our Sydney warehouse.
Measure temperature and relative humidity with this simple, Arduino-compatible sensor module based on the DHT22. With just three connections (GND, power, and data), you can read both temperature and humidity from a single I/O pin on your microcontroller. An Arduino library is available to make integration quick and easy.
The module includes mounting holes for M3 or 1/8" bolts and a flat rear face, so it can be easily bolted or glued into your enclosure. Designed and made in Australia by Freetronics.
