How does an automatic toilet flush work?
Automatic toilet flusher uses active infrared sensor technology which uses the emission and reception of infrared beams to detect the presence and movement of objects or people in their field of detection. When the sensor detected the body, it is ready to work. When people leave, it flushes water automatically.
How does a motion sensor work?
Motion sensors are like flashlights sending out a beam of light but with motion-detecting infrared energy waves instead of light waves. Just like a light is brighter closer to the bulb, the infrared radiation is denser nearer to the device and it spreads out farther away.
