Digit Outdoor Temperature & Humidity Sensor

Introduction

 

CHD 301C1 is temperature & humidit sensor with high reliability and superior stability.

With big LED display, people can examine local temperature and humidity

 

Via RS485 / 422 network communication, one PC can load 254 sensors to compose a surveillance system, at most  254×16=4046 pieces sensors can be managed

 

Main features are as follows

 

*  RS485 or RS422 Double Bus guarantee the safety of device communication

*  Big LED display,real time show local temperature and humidity

*  With button to control backlight, which can automatically turn off after 10 sec delay time

*  Large temperature range, sensor can be separated with control part

*  Measurement range can be set. It can set congealing dew resistance function and real time alarm when exceeding.

* 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.
