{"product_id":"mini-project-on-laser-light-security-system","title":"Mini Project On Laser Light Security System","description":"The \u003cstrong\u003eLaser Light Security System\u003c\/strong\u003e main purpose in making this project is that how do we make a security system device using a laser diode. We can use it anywhere like at the home, office, or in defence. In this, we have used some simple components like laser diode, 555 timers, LDR, resistance, and capacitors. In this kit, we also learn how PCB soldering and testing are done.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMini Project Security System\u003c\/strong\u003e has used a laser diode and an LDR (Light-dependent resistor). When we keep the laser diode face towards the LDR, then all the light of the laser falls directly on the LDR. In this condition no buzzer will sound as soon as there is an interrupt meaning any object comes between the diode and the LDR, a buzzer will sound in that condition.\u003cbr\u003e\u003cbr\u003eThis \u003cstrong\u003eOn Laser Light Security System Project\u003c\/strong\u003e is very simple, the LDR which is installed in it gives an analog signal and this analog signal goes directly to the comparator IC LM358 Which converts the analog signal into a digital signal, the same digital signal goes to the 555 timer which provides timing how long will the buzzer last.\u003cbr\u003e\u003cbr\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 alt=\"Laser-security-alarm-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Laser-security-alarm.jpg?v=1633082681\" 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 title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/WSuwo2B3GzA\" 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":40708885381301,"sku":"LGKT090","price":399.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708885414069,"sku":"LGKT090_R","price":599.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/Laser-Light-Security-Alarm.jpg?v=1633083539","url":"https:\/\/kitsguru.com\/de\/products\/mini-project-on-laser-light-security-system","provider":"KitsGuru","version":"1.0","type":"link"}
