Capacitive level switch introduction

Capacitive level switch introduction
       Capacitive level switch is used to detect the change of the small capacitance (usually PF) caused by the change of liquid level, and is processed by a dedicated ADA capacitor detection chip (can output a variety of signal communication protocols, such as: IO, BCD, PWM, UART, IIC...) to detect the water level and output a signal to the output.
       The big advantage of capacitive liquid level detection is that it can detect the change of water level or liquid in the container through any medium, which greatly expands the practical application, and effectively avoids the disadvantages of the stability and reliability of the traditional liquid level detection method.
       In some special areas that cannot be detected, the capacitive level switch of the ADA capacitance detection chip with built-in MCU dual-core processing can realize many special control functions and even realize more integrated and intelligent water level detection functions, such as The water level change after power-off in solar water heaters, coffee pots, etc. can also reliably detect the current water level. Capacitive liquid level detection is the current detection method in the liquid level switch.
