Water immersion module

WS11 (Water Sensor-MC11S) is a capacitive, non-contact sensing intelligent water immersion module, integrated with high integration differential split digital capacitive chip MC11S. MCU is embedded in the module, through the UART output capacitor and detection status information, to effectively filter out the vibration, condensation and other interference, to realize the accurate distinction of water / no water and different states, and to provide environmental temperature information at the same time.

WS11 water module can penetrate 1-10mm non-metallic container wall, measure whether there are different capacitor changes of liquid, effectively overcome the problems such as thick container wall, or air interval; has the advantages of strong penetration, high measurement accuracy, convenient use, it is widely used for waterproof and leakage detection in smart home, machine room, building, underground pipeline, tunnel and other scenarios.
