{"product_id":"wireless-alarm-using-rf-module","title":"Wireless Alarm using RF Module","description":"\u003cstrong\u003eWireless Alarm Using RF Module\u003c\/strong\u003e is designed as a security system that can be controlled wirelessly using the RF module. In the kit Wireless Alarm Using RF Module HT12E encoder IC takes a 4-bit binary sequence from the DIP switch. Each binary sequence notifies the identity of the item. Since we have used a 4-bit channel, we can allocate 16 items (in our case four). The encoder converts this four-bit binary sequence into serial data with address data latched with it. \u003cbr\u003e\u003cbr\u003eThe signal generated from the encoder is not strong enough to be transmitted for quiet fine ranges of distance so this needs to be modulated and transmitted over a carrier. We have used an \u003cstrong\u003eRF Transmitter\u003c\/strong\u003e working on 433 MHz, 4800bps baud-rate, and uses ASK modulation technique to serve this purpose. Thus, the data lines of the IC are used to differentiate between different ids and these are transmitted over the RF channel. \u003cbr\u003e\u003cbr\u003eThe next section is the RF receiver. There is an 8 terminal RF receiver that has the same properties as configured for the RF transmitter. It receives the serial data wirelessly depending upon the RF communication protocol. The receiver sends the serial data to the HT12D IC, which converts this serial data in parallel data of 4-bit, the same as enabled on the transmitter end. It indicates \u003cstrong\u003eAlarm \u003c\/strong\u003eAs\u003cstrong\u003e Output\u003c\/strong\u003e.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv style=\"text-align: start;\" id=\"p_info\"\u003e\u003cimg alt=\"security-system-using-rf-module-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/security-system-using-rf-module.jpg?v=1632719837\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions (cm) L x W x H : 20 x 15 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/_GzIQeqg6Bc\" title=\"YouTube video player\" width=\"800\" height=\"400\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" width=\"800\" height=\"400\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" width=\"800\" height=\"400\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF KIT","offer_id":40708844093621,"sku":"LGKT016","price":699.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE KIT","offer_id":40708844126389,"sku":"LGKT116_R","price":899.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/wireless-alarm-kit.jpg?v=1632720472","url":"https:\/\/kitsguru.com\/fr\/products\/wireless-alarm-using-rf-module","provider":"KitsGuru","version":"1.0","type":"link"}
