Ambient temperature, humidity, light and other parameters are very important data in industrial and agricultural production and scientific research, especially the measurement and control of temperature and humidity parameters in the environment of machine rooms, grain depots, greenhouses, and greenhouses. The traditional temperature and humidity monitoring system based on the wired communication system requires a lot of manpower and material to lay the line, which has a large amount of construction and a long installation time. However, the environmental parameter monitoring system based on the wireless transmission technology has obvious advantages over upgrade and maintenance. Work is also easier.

At the same time, GPRS DTU is used as the data transmission part of the system, and parameter thresholds can also be set. When a certain parameter value exceeds the specified value, a short message alarm is sent to the designated mobile phone.
