Specification

Description

The PIR Motion Sensor Detector Module HC-SR501 allows you to sense motion. It is always used to detect the motion of a human body within the sensor’s range. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. … PIR sensors detect general movement but do not give information on whom or what moved. This HC-SR501 PIR motion sensor can turn on devices by detected motion.

The Module HC-SR501 PIR Sensor has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer. Repeat Trigger Selection Jumper is also available. This PIR Motion Sensor is Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc.

Great and Easy to use!

I have used these in a hallway in my house that is pitch black at night so that when I enter the hallway a few LED's light up. Works great and well packaged!

Seems to be a good product for the price

I haven't checked accuracy yet or motion detection in a larger room, but seems to work well so far.

Works well, pin configuration is different than most standard docs online

Works well, but the pin configuration is a different that most standard docs for similar products online, so it took a bit of doing to get it to work. Seems to work well once the wiring is correct

Unreliable

 Even on the lowest sensitivity, they react to heat, light bulbs, and air movement. Unreliable. There is also an annoying four second delay before motion can be detected again.

Great for projects

My first impression is that these are great little sensors.They seem to detect motion well and hookup is really easy.They work perfectly to drive the 5 volt input of a relay module; when I get time to experiment I'll see what they can really do.
