The two of them are vcc 5v and Gnd. The third one is output from this module. The signal goes high when motion is detected. The output signal is 3.3v compliant. From your system after providing power you check the 3 rd pin for motion detection **Q: Will it also detect the opening and closing of the door???** A: Yes .We can provide you all support regarding this like ckt diagram ,other arrangements if you buy from us only **Q: can it be connected to led 12volt tube** A: You will need a relay module to switch the 12V Tube. Interface it with a 5V relay module. **Q: Hello i am thomas.i need to operate my own street light when the presents of a human during night.can we use relay system?if yes,share connection ckt** A: Yes you can give direct connection to relay board (with driver) also you can have arduino and LDR for light sensing ## Customer Reviews ### ⭐⭐⭐⭐⭐ good product *by P***R on 21 September 2023* but the there is no precise or dezire output ### ⭐ Very bad *by T***L on 23 August 2024* 5 समझ के लिया था बहुत महंगा पड़ गया, कोरोना काल मे वापसी भी नहीं हो पाया ### ⭐⭐⭐⭐ This is a simple and useful device but somewhat tricky for first time user *by P***R on 30 December 2016* This is a simple and useful device but somewhat tricky for first time user. Its could sense movement at a range of up to 10 feet. It has two presets which set two separate delay timings. When this device detects movement of a person, after a certain delay, its output pin changes state. This delay can be as low as 5 seconds and as high as 300 seconds. The second delay decides, how much time the output will remain in true state and then automatically revert back to false state. I tested it with Arduino but you can use it with any microcontroller or also drive a small relay coil with it to sound a buzzer or switch on a lamp. --- ## 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/64761036-hiletgo-d-sun-hc-sr501-pyroelectric-infrared-pir-motion-sensor](https://www.desertcart.tn/products/64761036-hiletgo-d-sun-hc-sr501-pyroelectric-infrared-pir-motion-sensor) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-14*
