This sensor adopts PE waterproof shell, which is suitable for outdoor and high humidity places, which can effectively increase the service life of the sensor. The sensor is small, powerful, 485 digital communication, can be directly connected to the HMI touch screen, flexible parameter configuration and calibration, and the baud rate can be changed to meet the needs of various users. A recorder with more advanced functions can record up to 70,000 temperature and humidity data with date and easily record historical data.
The waterproof temperature and humidity recorder (sensor) of our company is small and exquisite, with high anti-water ability, can be applied outdoors or in the greenhouse, powerful, high accuracy, easy to use, flexible, Modbus protocol, easy to access various industrial control systems, networking The monitoring is more practical and convenient, and the number is more than 10, and batch customers will present integrated monitoring software.
485 temperature and humidity sensor interface is 4-wire, power input range is 5-12V DC (no positive and negative directions, both positive and negative connections work normally), 485 is a 2-wire standard interface, communication rate can be set from 600-921600bps, the factory default is 9600bps without parity, 1 stop bit, 8 data bits
The transmission protocol can be customized, the default is Modbus protocol, which is universal for industrial control.
