Hcsr501 datasheet

Learn about the PIR sensor HC SR5with explanation of its working, pin diagram and description, dimensions, range and PIR sensor datasheet. The PIR Sensor module allows you to sense motion. It is often referred to used PIR, Pyroelectric, Passive Infrared and IR Motion sensor.

The module has an on-board pyroelectric sensor, conditioning circuitry . It is commonly used in turning the lights on and off automatically when people arrive or leave.

It is very reliable for robot projects which need human detection. HC - SR5Datasheet PDF Download - PIR MOTION DETECTOR. LHI7探头设计，灵敏度高，可靠性强，超低电压工作模式，广泛应. Operating voltage range DC 4. S(adjustable) the range is (0.xx second to tens of second). DYP- ME003) Can be used with.

Nearly all PIRs will have slightly different specifications, although they all pretty much work the same. This is a simple motion sensor similar to what is found in motion activate lights and security systems. Two trimpots (the orange adjustment potentiometers on the side of this module) allow you to adjust the sensitivity and output hold delay (how long it will hold the output high after being triggered). Refer to the product photos.

See the Datasheet for details. Search this site: Products. It detects infrared radiation from a passing heat source. You can use this to make a motion detection device, a light switch, or you could string many together and you.

Sensitivity (up to 7m) and output duration (20s - 5min approx.) adjustable. Can be fitted with a LDR to provide inhibit in light function for security light switching. Supplied with a fresnel lens.

When it detects a motion, it adjusts output digital code on HIGH(V, analog 675). Hi Dave, thanks for the quick reply. The RT 1Meg preset, is that the time delay adjust pot?
