You may need to program the electronics that the module is connected to (e.g. an arduino) to make full use of its capabilities. **Q: How do you power these up anyone got a diagram** A: Depends on what you are using to control the sensor but a typical search for "HC-SR501 example" should respond with some circuit diagrams. Not certain how to add pictures to answer but that should work.

It fulfilled my expectations! An excellent piece of kit and SeeKool have been very good about supplying the necessary circuit diagram. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Worked well *by W***R on Reviewed in the United Kingdom on 17 January 2020* As described. Used for a Halloween project with the Raspberry Pi. Never used these type of sensor before, so wasn’t sure what to expect, but once I’d worked out the programming side of the input, they work fine. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars PIR Sensors... *by D***N on Reviewed in the United Kingdom on 19 January 2020* Bought for a Arduino project.Only used them for a short time but they work as expected.They are fairly cheap and easy to work with so worth the cash --- ## 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.co.uk/products/82377818-seekool-5pcs-hc-sr501-human-body-sensor-module-pyroelectric-infrared](https://www.desertcart.co.uk/products/82377818-seekool-5pcs-hc-sr501-human-body-sensor-module-pyroelectric-infrared) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-28*
