Intelligent high and low liquid level controller tank liquid level controller sensor high and low liquid level control valve

The intelligent non-contact water sensing capacitive liquid level sensor is used to detect whether there is liquid. When there is no liquid close to the sensor, due to the existence of the distributed capacitance sensor, the sensor has a certain electrostatic capacitance. When the liquid level rises, the sensor is slowly closed to the sensor. Said, the liquid parasitic capacitance is coupled to the static capacitance, the value of the capacitance sensor, the change signal of the capacitance is input to the control IC, the signal is converted, the change of capacitance is converted into a signal, and then a certain algorithm is used to detect and judge the degree of change, when the change exceeds When a certain threshold is reached, the liquid level is considered to reach the induction point.
