A2 Triangulation Ranging Sensor Module Solution
30μA ultra-low power · ±2cm accuracy · Dual-stage water saving · IP67 probe
Solution Positioning
Dedicated sensor control solution for public squat toilet flushing. Features GIBO proprietary triangulation ranging technology with ultra-low power MCU, precisely detecting human presence and departure for automated flushing. Solves systematic flushing management problems in public restrooms.
Working Principle
Optical Triangulation Ranging
Unlike conventional IR threshold sensing, adopts optical triangulation + ultra-low power MCU processing. Emitter sends IR beam at fixed angle; receiver array calculates actual distance from光点 offset with trigonometric algorithm. Achieves mm-level precision ranging.
Key Features
1. Triangulation High Precision
Distinguishes standing/squatting/bending postures. Provides precise data for smart flushing decisions.
2. Anti-False-Trigger Logic
Trajectory analysis filters non-usage behavior (cleaning mops, brief bending). Configurable protection time 5-30s.
3. Dual-Stage Flushing
Pre-rinse (0.3-0.5L) wets ceramic surface, then main flush (3-6L) cleans thoroughly. 30%+ water saving.
4. Ultra-Low Power
30μA standby current. 12+ months battery life at 200 uses/day. AC/DC dual power supported.
5. Self-Adaptive Calibration
Post-installation auto-calibration scans environment parameters. Plug-and-play, no manual tuning needed.
6. Low Water Hammer Design
Core tech (#15). Gradual valve closing reduces water hammer peak by 60%+.
7. Self-Cleaning Solenoid
Core tech (#16). Each cycle flushes valve core to prevent scale/silt blockage. Extends maintenance interval.
8. IP67 Probe Protection
Sensor probe encapsulated IP67. Control box IP65. Stable in high-humidity restroom environments.
