Introduction to LED Motion Sensor Chip

LED motion sensor chip, also known as photoelectric motion sensor chip, is a kind of sensor that detects the change of light intensity in a certain range. When the sensor detects a change in light intensity, it will generate a signal to trigger the corresponding control circuit, thus achieving the purpose of motion detection. LED motion sensor chips are widely used in various fields due to their high sensitivity, low power consumption, and small size.

Working Principle of LED Motion Sensor Chip

The working principle of LED motion sensor chip is based on the photoelectric effect. The sensor consists of a light-emitting diode (LED) and a photoelectric transistor. When the LED emits light, the photoelectric transistor will generate a current according to the intensity of the incident light. When the sensor detects a change in light intensity, the output current of the photoelectric transistor will change accordingly, and the control circuit will generate a signal to trigger the corresponding action.
