CHD301C(V5.0) temperature & humidity sensor is a high-tech product with high reliability and superior stability. With big LCD display, people can examine local temperature and humidity; Meanwhile, the sensor can indicate the actual alarm status via arrowhead. Through RS485 network communication, one PC can load 254 sensors to compose a monitoring system, in which, at most 254 x16=4064 pieces sensors can be managed. Featured with smart appearance, prompt reaction, high anti-interference ability, low power consumption, 3 class thunder-proof protection, meeting anti- explosion requirements, etc, it is most suitable for telecom base station, big warehouse, equipment or computer room and those places that have strict requirements in temperature & humidity and accurate real time monitor.

Main features are as follows:

RS485 Bus guarantee the safety of device communication;
Big LED display, real time show local temperature, humidity and alarm status (fluctuate arrowhead);
The sensor chip is separated with controlling part, which is good for the ventilation between the chip and outside, improve the measuring precision.
Measurement upper and lower range can be set. It is real time OC output when exceeding the upper and lower limit.
Strong anti-interference, low power consumption and 3 grade thunderproof protection;
Featured with exacurate and stable measuring, high precision and good value for money, etc.
