Description: Based on optics principles,its interior has 1 LED ,2 photosensitive receiving triode; and the other side has one cylindrical shade. colour: Blue Material: metal +PC size: 10x15MM Package Contents: 1 x RPI-1031 Angle Sensor Module)\u003c\/p\u003e","brand":"Shop2IndiaBei","offers":[{"title":"Default Title","offer_id":43027795673256,"sku":"U2I-2-254354479674","price":1290.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/1588\/1354\/products\/256568-1__99345.jpg?v=1672511713","url":"https:\/\/shop2india.com\/products\/2x-rpi-1031-angle-sensor-module-4dof-attitude-hm-led-for-arduino","provider":"SHOP2INDIA GATEWAY","version":"1.0","type":"link"}
