Automatic temperature compensation type soil water tension meter system and determination method

The invention relates to an automatic temperature compensation type soil water tension meter system and a determination method. The system is composed of a tension meter end and a control center end, wherein the tension meter end and the control center end transmit by virtue of a wireless signal; the tension meter end comprises a tension meter and a data acquisition and processing transmitter; the tension meter is internally provided with a pressure sensor and a temperature sensor; all the sensors are connected with the data acquisition and processing transmitter; the control center end comprises a computer and a receiver; the receiver and the data acquisition and processing transmitter of the tension meter end wirelessly transmit data or instructions. According to the automatic temperature compensation type soil water tension meter system and the determination method, the errors of the tension meter system, caused by the change of environment temperatures, are reduced. Meanwhile, temperature and water content conditions of a soil environment can be subjected to all-weather real-time monitoring; the data acquisition amount is great and the data can be automatically uploaded to a central controller to realize water management.
