digital temperature and humidity sensor

RS485 LCD display temperature and humidity sensor

rs485 temperature humidity sensor with a T+RH probe on the cable can measure the value of relative humidity and absolute humidity in the air. Outdoor or indoor use. 

Have sound and light alarm

Network monitoring data real-time upload. 

high temperature and humidity sensor reviews:

1, Swiss imported thermometry unit, high precision, anti-interference ability. 

2, built-in memory devices, temperature, and humidity data recorded in real-time, the maximum recordable 65535 group. 

3, the alarm can be set various parameters, communication parameters, such as date and time through the liquid crystal keys. 

4, the liquid crystal display real-time temperature, humidity, time and date, it has a storage capacity, the device address, and baud rate. 

5, alarm parameters may be performed by monitoring the temperature and humidity internet, remote measurement, and setting parameters of the call date and time, recording parameters. 

6, the built-in alarm function of temperature and humidity, temperature, and humidity may be upper and lower hysteresis and alarm settings. 

7, having a 2 Road switch quantity signal output, can be associated with the alarm output. 

8, all the way to the alarm buzzer, all the way to the external alarm sound and light alarm. 

9, a variety of recording modes, the device may be connected to monitor the temperature and humidity internet data is sequentially recorded by the automatic splicing time. 

10, RS485 signal output, as far as communication distance up to 2000 meters, the lightning protection design, safe and reliable. 

11, 10 ~ 30 V wide supply voltage input.
