With the penetration of IoT technology into water purifiers, simple "on/off" detection is no longer sufficient. OEMs require stable, bounce-free level signals for MCU acquisition. The signal quality of a non-contact liquid level sensor is crucial.
The capacitive sensors from Shenzhen Xingkechuang Technology Co., Ltd. feature built-in Schmitt triggers and debouncing algorithms, outputting clean high/low logic levels or open-collector signals. When the water level crosses the sensing area of the probe adhering to the outer wall, the signal edge is crisp with no multiple bounces, preventing the main control board from misjudging and causing frequent pump starts/stops.
Xingkechuang engineers can provide circuit matching suggestions for water purifier customers (supporting wide voltage supply of 3.3V/5V/12V/24V), ensuring seamless integration between the sensor and smart control boards, supporting smart features like low-water App pop-ups and full-water auto-standby.
