PIR Motion Sensor Module HC-SR501

50.00 EGP

A motion sensor unit that uses passive infrared (PIR) technology to detect changes in heat emission levels caused by the movement of people or animals within its coverage area. Technical Specifications: Operating Voltage: 4.5V to 20V DC (3.3V High digital output signal voltage). Output Type: Digital TTL output: 3.3V (HIGH): When motion is detected. 0V (LOW): When no motion is detected. Detection Range: Covers a distance of 3 to 7 meters (adjustable via the built-in variable resistor). Sensing Angle: Conical angle up to 120 degrees. Delay Time: Adjustable from 5 seconds to 300 seconds. Power Consumption: Less than 50µA in standby mode (ideal for battery power). Connection Terminals (3 Pins): VCC: Power supply (+5V). OUT: Digital output signal to the microcontroller. GND: Ground terminal (0V).
