QB066 PIR Motion Sensor

Human infrared sensor is used to detect the infrared radiation emitted by the human or animal body module, when someone or other hot objects enter the sensor's sensing range, the object will cause changes in the infrared radiation. Its characteristic is that only when the external radiation causes its own temperature to change, it gives a corresponding electrical signal, when the temperature change tends to be stable, there will be no signal output, so it is only sensitive to the moving human body. Application reference: human body sensor light, automatic door, automatic faucet, automatic stair lighting, etc. Click to explore: PIR Motion Sensor Doc Parameter Specification Parameters Value/Description Operating voltage 3.3V~5V Operating temperature -20 C~+85 C Detection Angle 100 Detection range 0~4m Size 3.16cm*2.38cm
