🚀 Elevate your smart projects with motion sensing that never sleeps!
The HiLetgo HC-SR501 PIR Infrared Sensor is a compact, energy-efficient motion detection module compatible with Arduino and Raspberry Pi. Operating on a wide voltage range (4.5-20V) and featuring an adjustable delay time (5-200 seconds), it reliably senses human movement within a 100° cone angle. Ideal for security, automation, and smart lighting applications, this sensor empowers professionals to build responsive environments with precision and low power consumption.

Works good
Works as good as it says.

No Pins for H and L
the product didn't come with a jumper set and there were no pins for the H and L although they were in the photo!

working good with arduino.

I ordered for my kid for experimenting with Arduino, he says they work great

Function: My order included 3 units. Each of these worked. The device has controls for adjusting duration triggered and sensitivity (detection distance). Once triggered the duration ranged 1sec to 6min. These values are consistent w/ the datasheet. I did not test sensitivity. Electrical Characteristics: Sensor pin output (Vout) range 3.19-3.33v across the input range tested (4-7v, datasheet recommended VCC range: 5-20v). PCB is approx. 24mm by 32mm (15/16inch x 1 1/4inch). Solder joints are clean. Would buy again.

Nifty little motion sensor. Easy to code and use with Arduino or Pico 2W. Nice feature is the ability to adjust time delay and sensitivity.
A**.
No repeated trigger connection and no LDR SLOT.
