The application of temperature and humidity in the grain depot, greenhouse, industrial safety and other monitoring caused a high degree of concern. In practical applications, data collection is often distributed, the features of strong mobility, resulting in traditional wired monitoring difficult wiring, along with the development of wireless sensor networks and remote transmission technology, real-time monitoring automation system has become a reality.

Happy coast KLHA R & D GPRS KG50A30, only need to open a GPRS SIM card, a simple set of parameters, you can connect to the serial device data transparent transmission to the public network fixed IP or domain name on the host.

Happy coast of KG50A30 GRPS DTU can not only transparent transmission, but also accept the server feedback command. The utility model is especially suitable for the transmission of multiple points, points, scattered and inconvenient wiring and real-time data. GPRS technology is a wireless transmission technology launched by China Mobile to achieve sensor data acquisition and remote data transmission area, this acquisition method has wide coverage, strong stability, high precision and advantage of a wide range of application environments.

GPRS DTU data transmission module KG50A30 to support serial communication, is a RS232/RS485/ voltage to GPRS three interface communication module, the use of this module can easily achieve two-way data transparent transmission. Using GPRS for remote transmission, low cost, good stability can be directly connected to a variety of monitoring equipment to achieve real-time monitoring of temperature, humidity, water and other data.
