Auto Tea Machine Steam Condensation False Alarms? External Capacitive Level Sensor for Precise Refill | Xingkechuang

Commercial tea machines run continuous brew cycles, so the water tank wall experiences

large temperature swings. Steam condenses into droplets that run down the wall;

photoelectric switches flicker between on and off, while float balls jam on tea-leaf debris. The

result is either a burnt-bottom dry-boil or a false-full that stops the inlet pump and ruins cup

volume consistency.

Xingkechuang's non-contact level sensor sticks to the tea machine tank exterior. The

capacitive principle leverages the water/air εr gap — only a genuine water-level crossing

flips the output. Condensation droplets and brewing mist never trigger. Shenzhen

Xingkechuang Technology Co., Ltd. supports custom probe placement based on 3D tank

drawings, with dual low-water/full-water outputs connecting directly to GPIO for noticeably

better cup-volume consistenc
