Mobile Toilet Infrared Sensing

Infrared sensing technology in mobile toilets is mainly applied to occupancy sensors and sensor-activated sanitary fixtures, achieving automated control through the principle of infrared reflection, offering advantages such as efficiency, water conservation, and hygiene.

Occupancy Sensors

In smart public toilets, occupancy sensors often use 86-panel infrared sensors, with the core function of detecting whether the toilet is occupied through infrared signals. Two points should be noted during installation:

1. Base Box Height: Adjust according to the toilet's spatial layout and user habits, typically installed at an appropriate position on the door frame or wall to ensure a reasonable signal coverage area.
2. Polarity Identification of Wiring Terminals: The sensor needs to be connected to the power supply and control system. During wiring, strictly distinguish between positive and negative terminals to avoid short circuits or signal interference, ensuring stable operation of the device.
   Such sensors emit infrared light and receive reflected signals. When a person enters the detection range, changes in the reflected signal trigger the system to determine an "occupied" state; otherwise, it is considered "unoccupied," providing real-time data support for toilet management.

Sensor-Activated Sanitary Fixtures

Infrared sensor-activated sanitary fixtures achieve automatic water on/off through the principle of infrared reflection. Common devices include sensor-activated faucets and urinals, with the following working principles:

1. Core Components: Composed of an infrared emitter tube, receiver tube, pulse solenoid valve, and microcomputer processing system. The emitter tube continuously emits infrared light, the receiver tube captures reflected signals, and the microcomputer processing system analyzes signal changes to control the solenoid valve's on/off state.
2. Workflow: When a person enters the sensing area (e.g., hands approach the faucet or stand in front of the urinal), infrared light is reflected back to the receiver tube, triggering the solenoid valve to open and release water; after the person leaves, the reflected signal disappears, and the solenoid valve closes, achieving automated control of "water on when someone arrives, water off when someone leaves."
3. Functional Advantages:
   • Water Conservation: Avoids water waste caused by traditional manual fixtures not being turned off or leaking, with a water-saving rate of up to 30%-50%.
   • Hygiene: Reduces hand contact, lowering the risk of cross-infection, especially suitable for public places.
   • Durability: The solenoid valve and microcomputer system have a long design life, with low maintenance costs.

Infrared sensing technology significantly enhances the intelligence level and user experience of mobile toilets through non-contact interaction, serving as an important technological support for modern public sanitation facilities.
