The temperature and humidity detection module

·Introduction:

Liquid crystal temperature and humidity detection module uses the RS485 bus transmission. With the background of management software, real-time detection and management for environment temperature and humidity can be achieved..

·Application Fields:

Products are widely used in the power room, HVAC, electrical, mobile communication base station, computer room, warehouse, textile industry, food industry, tobacco industry and other measurement sites that require the environmental temperature and humidity monitoring and industrial automation field.

·Features:

■Real-time collection of environment temperature and humidity;
■Modbus RTU communication interface can be compatible with other interface,and convenient to expand;
■Support real-time detection for temperature and humidity and single temperature;
■Support full duplex mode;
■Provides two RJ45 interfaces, which is convenient for users to cascade and extend;
■Through temperature and humidity module communication indication, it intuitively displays temperature and humidity module working condition and communication state;
■It adopts digital temperature and humidity sensors and requires no checking, with small size, low power consumption, strong anti-interference ability.It can provide the dew point parameters and measure the absolute humidity. In gel cases, humidity value is 100%;
■Watchdog is built in, to ensure that the temperature and humidity it detects are more reliable and real-time.
