The 3.3v "trigger" pin (the "OUT") even had enough juice to directly power a red LED (tho a little dimmer than normal). Very wide sensitivity pattern. Tho description says "< 100 degrees" I thought it was greater than 120. At default sensitivity it would trigger easily from 8-10' away. I never adjusted it as that was the perfect distance for my needs. Holding it with the sensor "dome" facing down and the adjusting (orange) "screws" facing you, the left one is the sensitivity, the right is the duration that the OUT pin will stay "on" (i.e. hold at 3.3v). Minimum seems to be around 4 seconds. Review: These are useless as motion detectors due to the false reports. Yes I tried the pF capacitor from Signal to Ground and I shortened the signal wire. It did reduce the false motions but they still happen few minutes. Unfortunately I can't send them back due to adding the capacitor to the circuit. I would not recommend these to anyone. I will try to keep fussing with them. I am trying now on a Wemos D1 Mini with less than 1 cm of signal wire from PIR to data pin. UPDATE: Still bad on the wemos with <1 cm wire. Tried pull up resistor - no effect. Increased and decreased capacitor size - no effect. I've ordered a different type. Hope they work. ## Features - Using Potentiometer 105, output timing is from 0.5S to 200S - Widely used in:Security Products,human body sensors toys,human body sensor lighting industrial automation and control, etc - NOTE: On this retrigger jumper is a solder jumper, and you need solder it by yourself - Pls note that there is no IR emitter in this module, the principle of PIR sensor is to detect the infrared radiation emitted by the human body, it only have a IR sensor (cell) - Package Included: 5 X HC-SR501 PIR Infared Sensor ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B012ZZ4LPM | | ASIN | B012ZZ4LPM | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #180,393 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #342 in Motion Detectors | | Color | HC-SR501 | | Customer Reviews | 4.3 4.3 out of 5 stars (516) | | Customer reviews | 4.3 4.3 out of 5 stars (516) | | Date First Available | 5 February 2016 | | Date First Available | 5 February 2016 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 44.7 g | | Item model number | 4331029690 | | Item model number | 4331029690 | | Manufacturer | DIYmall | | Manufacturer | DIYmall | | Part number | FZ0057- | | Plug Profile | Wall Mount | | Power source type | Battery Powered | | Product Dimensions | 3 x 2.49 x 2.01 cm; 44.79 g | | Product Dimensions | 3 x 2.49 x 2.01 cm; 44.79 g | | Size | PIR sensor | | tech_spec_battery_description_toys | Battery not included | ## Product Details - **Brand:** DIYmall - **Colour:** HC-SR501 - **Item weight:** 1.58 Ounces - **Maximum range:** 15 Feet - **Power source:** Battery Powered ## Images ![5 Pack HC-SR501 Pir Motion IR Sensor Body Module Infrared for Arduino - Image 1](https://m.media-amazon.com/images/I/515XvPTaTSL.jpg) ## Questions & Answers **Q: Is the sensitivity adjustable?** A: Yes there are two pots on the board you can use to adjust. Check the web for how to do it. **Q: Can i hook this directly to the item i want to switch? it’s dc current.** A: WRCoyle is pretty much wrong on their answer. I'm assuming you want to turn electricity on to another device with this? The answer to that is no. This provides a logic output that is high when it is triggered and low when on standby. The BISS0001 chip on this has the output pin rated for 10mA and it goes straight to the out pin on the board, no transistor used to handle more power. It can run a regular LED using a resistor to limit the LED to 10mA or less. Beyond that, you will need a transistor or solid state relay or some other setup to handle any amount of current. **Q: How would you describe the range and sensitivity of these? I need to detect when motion stops in a 12x14 room of people.** A: It will sense any movement (heating moving paper) in a room of that size **Q: Could this be used to replace a faulty IR sensor on animated halloween props?** A: The pir sensor should work but the output is simply a logic level output. It will not provide much current. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***B on 2 November 2017* Hooked the VCC and ground to a 12v A/C adapter and it worked perfect.

I decided to go the DIY route and bought these. I connected one to a NodeMCU, which I set up with Home Assistant using MQTT (along with a simple 'smart' switch sans motion sensor). It's awesome, gives me so much more control and cheaper. I do get some false-positives, but not nearly as much as with the pre-built unit. I suspect it's due to being in the garage and the sensor picking up sunlight/shadows coming in through cracks in the garage door. Overall, very happy with the purchase. ## Frequently Bought Together - DIYmall 5 Pack HC-SR501 Pir Motion IR Sensor Body Module Infrared for Arduino - 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 - Arduino Uno REV3 [A000066] – ATmega328P Microcontroller, 16MHz, 14 Digital I/O Pins, 6 Analog Inputs, 32KB Flash, USB Connectivity, Compatible with Arduino IDE for DIY Projects and Prototyping --- ## 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.in/products/273261205-5-pack-hc-sr501-pir-motion-ir-sensor-body-module](https://www.desertcart.in/products/273261205-5-pack-hc-sr501-pir-motion-ir-sensor-body-module) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-06-21*
