It uses an integrated digital body pyroelectric infrared sensor, has smaller size, higher reliability, lower power consumption and simpler peripheral circuit.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003e Specifications\u003c\/h3\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eInput Voltage: 3.3 ~ 5V, 6V Maximum\u003c\/li\u003e\n\u003cli\u003eWorking Current: 15uA\u003c\/li\u003e\n\u003cli\u003eWorking Temperature: -20 ~ 85\u003c\/li\u003e\n\u003cli\u003eOutput Voltage: High 3V, low 0V\u003c\/li\u003e\n\u003cli\u003eOutput Delay Time (High Level): About 2.3 to 3 Seconds\u003c\/li\u003e\n\u003cli\u003eDetection angle: 100 °\u003c\/li\u003e\n\u003cli\u003eDetection distance: 7 meters\u003c\/li\u003e\n\u003cli\u003eOutput Indicator LED (When output HIGH, it will be ON)\u003c\/li\u003e\n\u003cli\u003ePin limit current: 100mA\u003c\/li\u003e\n\u003cli\u003eSize: 30*20mm\u003c\/li\u003e\n\u003cli\u003eWeight: 4g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"KEYESTUDIO","offers":[{"title":"Default Title","offer_id":30120429191230,"sku":"KS0052","price":94.99,"currency_code":"NAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0108\/4928\/8254\/files\/Keyestudio_PIR_Motion_Sensor_for_Arduino_04.png?v=1730899991"},{"product_id":"keyestudio-tcs3200-color-recognition-sensor-detector-module-for-arduino","title":"KEYESTUDIO Color Recognition Sensor Detector Module for Arduino","description":"\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cspan\u003eThe \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003eKEYESTUDIO TCS3200 Color Recognition Sensor Detector Module\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e makes it easy to detect and identify colours in your Arduino and microcontroller projects.
