HC-SR501 PIR Adjustable Motion Sensor

With this sensor, you can detect live movements from a range of 3-4 meters.

PIR sensors are sensors used to detect the movement of living things in an environment. This tiny sensor is a module that you can easily use in various electronics, robotics and hobby applications, and can be used with many microcontroller platforms, especially Arduino.

This module, which has a digital output, gives a logic 0 output when it does not detect motion in the environment, and a logic 1 output when it detects motion. There are two potentiometers on the sensor, Sx and Tx. The Sx potentiometer changes the viewing distance of the sensor between 3 and 5 meters. The Tx pot sets how long it will give the logic 1 (3.3V) output from the output pin after the sensor sees it.
