You just need a way of reading the values coming from the sensor to detect motion. **Q: range please - how far away can it be from the surface that you are measuring?** A: Depends on the sensitivity setting. I have had no problems in the 2 to 3 meter range which is perfect for my uses. Also, this is an infrared sensor that senses motion, so if your surface is stationery, you might consider an ultrasonic sensor instead. **Q: What is the field of view at 20 ft.?** A: It's pretty good, full range in 2 more feet **Q: What are the dimensions of this? Specifically looking at the depth of the white dome and size of the white square. Trying to hide in woodworking.** A: From the dome top to the top of the square is .5" The square is .913" on a side ## Customer Reviews ### ⭐⭐⭐⭐ Works good *by T***N on 4 March 2024* Works as good as it says. ### ⭐ No Pins for H and L *by O***A on 16 June 2022* 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! ### ⭐⭐⭐⭐⭐ Good working *by I***M on 31 January 2025* working good with arduino. ## Frequently Bought Together - HiLetgo 3pcs HC-SR501 PIR Infrared Sensor Human Body Infrared Motion Module for Arduino Raspberry Pi - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - HiLetgo 3pcs AM312 Mini Pyroelectric PIR Human Sensor Module PIR Infrared IR Sensor Body Manual Motion Infrared IR Detector --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/256334295-hiletgo-3pcs-hc-sr501-pir-infrared-sensor-human-body-infrared](https://www.desertcart.tn/products/256334295-hiletgo-3pcs-hc-sr501-pir-infrared-sensor-human-body-infrared) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-01*
