Problems solved by technology

Because this kind of sensor is made of the piezoresistive effect of single crystal silicon, its piezoresistive coefficient changes with temperature, and the principle of piezoresistive effect itself can cause the temperature drift of the sensor output
In addition, the manufacturing process of semiconductor sensitive components will also bring about the overall temperature drift of the sensor, which requires an effective method to solve the defects caused by the pressure sensor itself being susceptible to temperature influence

Description

technical field [0001] The invention relates to a water level detection system, in particular to a water level detection system with pressure compensation, which belongs to the field of water level detection. Background technique [0002] In recent years, with the continuous improvement of my country's geological exploration level, technologies such as water level detection, temperature detection, and metal content detection have become increasingly mature. However, when carrying out specific engineering applications, many factors need to be considered. The invention proposes a wireless remote detection method according to the situation that the geological exploration team is exploring mines and other natural environments that are harsh, unsuitable for motor vehicles to drive in, and staff members to stay for a long time. The pressure sensor in the detection system mostly uses single crystal silicon pressure sensor. Because this kind of sensor is made using the piezoresist...
