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). The 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 one meter of water. The T9501 is available in multiple cable lengths.
