We can do this in a house, office for the security region. If someone forcibly opens the gate an alarm will sound. In this, we have used some simple components like a transistor, magnetic switch, buzzer, and sum resistor \u0026amp; capacitors.\u003cbr\u003e\u003cbr\u003eThe\u003cstrong\u003e Multi Gate Door Bell Sensor \u003c\/strong\u003epurpose for making this project is that we can do it for security purposes. We can fit this kit in \u003cstrong\u003e3 different doors\u003c\/strong\u003e. You simply need to fit a small unit including a reed switch on each door frame and fix a magnet on the moving door such that the magnet aligns with the reed switch when the door is closed. As long as the door is closed, no sound will be generated, as soon as someone opens the door, and then in that condition, the contact of the reed switch will be removed from the magnet and the buzzer will ring. You have to do the same process in all three doors.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: start;\"\u003e\u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Multi-Gate-Door-Bell.jpg?v=1633075569\" alt=\"Multi-Gate-Door-Bell-block-diagram\"\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 title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/b5Fv00IXlW0\" height=\"400\" width=\"800\" 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 width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF","offer_id":40708885217461,"sku":"LGKT086","price":599.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708885250229,"sku":"LGKT086_R","price":699.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/multi-gate-door-doorbell-electronic-project.jpg?v=1633076045","url":"https:\/\/kitsguru.com\/fr\/products\/multi-gate-door-bell","provider":"KitsGuru","version":"1.0","type":"link"}
