IR Pyroelectric Infrared PIR Motion Sensing Detector Module

You can use this to detect people/animals based on their heat radiation (infra-red).

Specifications:

• Input Voltage: DC 4.5-20V
• Rest current : <50uA
• Level output: High 3.3 V /Low 0V
• Delay time is adjustable
• Sensitivity is adjustable from about 3 meter to 7 meter*
• Dimensions: 32mm*24mm
• Angle of the Sensor: <100 °
• Operating temperature: -15°C-+70°C
• Lens size: 23mm (diameter)

*The sensitivity is highly dependent on the object that radiates IR. Please take note that the distance is not adjustable, only the sensitivity to IR radiation.

Pins:

• Vcc (left, side of 4-pin voltage regulator)
• Output (middle)
• GND/ground/min (right, on the side of the de 16-pin chip)

Note: This sensor may be sensitive to false positive triggers in combination with an ESP8266 based board or any other board with Wi-Fi/Bluethooth/RF.
