The sensor using PE waterproof shell, suitable for use in outdoor and high humidity places, can effectively increase the life of the sensor. The sensor is small, powerful, 485 digital communication, can be directly and HMI touch screen is directly connected, parameter configuration and calibration of flexible, can change the baud rate, applicable to a variety of user needs. More advanced features of the recorder, to record the date of the 70 thousand bands of temperature and humidity data, easy to record historical data.

The waterproof type temperature and humidity recorder (sensor) small, water capacity is high, can be outdoors or in application, strong function, high accuracy, easy to use, flexible and convenient access to the Modbus protocol, various industrial control systems, network monitoring more convenient, more than 10 customers as one batch, monitoring software.

485 temperature and humidity sensor interface for the 4 line, the power input range 5-12V DC (positive and negative direction, and then will work, 485) for 2 wire interface, the communication rate can be set from 600-921600bps to 9600bps, the factory default no parity, 1 stop bit, 8 data bits

Transport protocol can be customized, the default is Modbus protocol, industrial control.

The temperature and humidity sensors have a common 485 sensor function and temperature and humidity recorder function, if the temperature and humidity recorder function, please contact customer service specific advice.

With the function of temperature and humidity recorder version, can store 100 thousand historical temperature and humidity data, and can support the date of inquiry, with real-time clock function, record the date of the information with time. And with the temperature and humidity alarm function, alarm indicator lights flashing, buzzer sound indicator.

With temperature and humidity recorder function version, is very suitable for multi node networking applications, including cold chain transportation, warehouse environment monitoring, Museum Heritage monitoring and other occasions.
