Public restroom IoT renovations often hit pitfalls: water tank overflow, lights turning off when occupied, paper dispensers empty with no one notified. Shenzhen Xingkechuang Technology Co., Ltd. closes the loop with three sensors:XKC-Y28 non-contact capacitive level sensor adheres to the outer wall

Early IoT human sensing mostly used PIR (Passive Infrared). The moment a person moved, it triggered; the moment they sat down to read, the light went out. Human presence sensors use 60GHz mmWave (FMCW) to capture micro-motions of the chest from breathing, continuously outputting "occupied" even when

Diffuse infrared sensors emit infrared light and receive echoes reflected from objects, judging the presence and approximate distance of objects based on reflection intensity, without needing a paired reflector, making installation extremely simple.The KE200 from Shenzhen Xingkechuang Technology Co.

IoT water tank scenarios (water purifiers, irrigation tanks, medical water bags) fear drilling and leakage the most. The capacitive non-contact liquid level sensor senses water levels through the dielectric constant difference (water εr≈80, air≈1), with the probe adhering to the outer wall of the co

True IoT is not merely about "being connected" but about "perception + decision-making." In smart cities, smart home appliances, and industrial IoT, non-contact liquid level sensors (capacitive principle), diffuse infrared sensors, and human presence sensors form the most fundamental perception tria
