{"product_id":"mini-pir-motion-sensor","title":"Mini PIR Motion Sensor","description":"\u003cp\u003ePIR (Passive Infrared) sensors are used to detect motion, specifically things that emit heat radiation like humans and pets. They're commonly seen in the corners of rooms as part of an alarm system.\u003c\/p\u003e\n\u003cp\u003eThis is a mini PIR sensor, the tiny lil' bro of our standard PIR sensor. This smaller version is handy for prototyping as the pins pop straight into a breadboard, and the compact format also makes it better for embedding in your own projects and enclosures. Downsides? Slightly lesser range and takes a little longer to trigger.\u003c\/p\u003e\n\u003cp\u003eThese sensors pick up targets around the 5m range and are super easy and flexible to use - you can power it from 3-12V DC as it has an onboard regulator. Digital signal output is 3.3V high\/low, with the signal going high for 2 seconds when motion is detected.\u003c\/p\u003e\n\u003cp\u003eThe lens is focused to 2-5 meters away with a 100-degree spread.\u003c\/p\u003e\n\u003ch2\u003ePinout (Important!)\u003c\/h2\u003e\n\u003cp\u003ePin connections for your microcontroller are simple. \u003cstrong\u003eAlways power down\u003c\/strong\u003e your microcontroller before wiring up, \u003cstrong\u003eand triple check your connections\u003c\/strong\u003e as you may damage the sensor if wired incorrectly:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePin #1 to \u003cspan data-mce-fragment=\"1\"\u003e3-12V\u003c\/span\u003e (Pin 1 has the 'U' next to it - see below image)\u003c\/li\u003e\n\u003cli\u003ePin #2 to output signal\u003c\/li\u003e\n\u003cli\u003ePin #3 to GND \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/PIR-orientation.jpg?width=700\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"panel-collapse collapse in\" id=\"tab-technical-details-content\"\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAdafruit PIR tutorial\u003c\/li\u003e\n\u003cli\u003e\nOur own Mini PIR Raspberry Pi Pico tutorial (from our Maker Advent Calendar)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":43493249908813,"sku":"rla1787258126091","price":2.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/mini-pir-motion-sensor_1.jpg?v=1787258130","url":"https:\/\/www.grandorchard.shop\/products\/mini-pir-motion-sensor","provider":"My Store","version":"1.0","type":"link"}
