The Telaire T9501 series temperature and humidity sensor is based on a capacitive polymer sensor chip and ASIC integrated into an easy-mount OEM package. It is simple and ready to use without further calibration or temperature compensation. The sensor output is modbus digital RS485-configurable with a 115,200 baud rate (with fault-protection). T9501 harsh environment temperature and humidity sensor is IP67-rated, meaning that it is completely protected against the ingress of dust and airborne particles, as well as water and liquids, up to and including immersion in up to 1 meter of water. The T9501 is available in multiple cable lengths.
