Coffee machine drip trays collect extraction residue and coffee grounds. Left sitting, this develops sour-smelling biofilm. Optical lenses turn green within three days; float switches jam on grounds. Overflowing residue back-flowing into the tray motor is a frequent commercial machine complaint.
Xingkechuang's non-contact solution sticks to the outside of the drip tray wall. The capacitive principle judges overall dielectric state. Biofilm ΔC is minimal and filtered out; only the real liquid level reaching the detection point triggers the full alarm. The sensor never touches dirty water, complying with electrical isolation safety standards. Shenzhen Xingkechuang Technology Co., Ltd.'s XKC-Y29A supports both NPN and high/low level outputs, connecting directly to the full-tray indicator light.
