1. Product Overview
This multi-functional simplified control mainboard integrates radar-sensing auto-lid/seat, intelligent seat heating, foot sensor control (flush + lid opening), and soft night light, designed for mid-to-high-end smart toilets. Featuring industrial waterproofing and low-power design.
Key Advantages:
✔ Touchless Control: 24GHz mmWave radar (more accurate than IR, anti-interference)
✔ Foot-sensing Control: flush/ open lid
✔ Energy Efficiency: 4-stage seat heating (30°C-45°C) with timer
✔ Robust Protection: IPX5 full-board potting, triple safeguards (over-current/voltage/temp)
