PIR Sensor HC-SR501 Adjustable

PIR Sensor

The HC-SR501 is an adjustable infrared motion detection sensor based on the passive infrared (PIR) technology. It is commonly used in various applications such as security systems, lighting controls, and automation. The sensor is capable of detecting motion within a certain range and triggering an output signal to activate a related device. The detection range, delay time, and trigger mode can be adjusted to meet different needs. The compact size and easy-to-use design make the HC-SR501 an ideal choice for various motion sensing applications.

The sensor has two potentiometers, Sx and Tx. The Sx potentiometer adjusts the viewing distance of the sensor between 3 to 5 meters. The Tx potentiometer sets how long the output pin will remain at logic 1 (3.3V) after the sensor detects motion.
