PIR MOTION SENSOR

• voltage: 5 VDC * connection: 3 pin: GND, VCC and OUT * adjustments: sensitivity and delay (by trimmer)
• * delay on time: 3 to 200 s * output level: high = 3 V, Low = 0 V
• * max. sensor distance: 7 m ( 23 ' ) * operating temperature: -15 to +70°C ( 5 to 158 °F ) * detection angle: 120 °

PIR sensors allow to sense motion, almost always used to detect whether a human has moved in or out of the sensor's range.
