{"product_id":"touch-sensor-using-555-timer","title":"Touch Sensor using 555 timer","description":"\u003cp\u003eThis \u003cstrong\u003eTouch Sensor using a 555 timer\u003c\/strong\u003e is a very simple touch sensor switch that is built with the 555 timer IC. You just need to touch the metal plate and the led gets energized and is kept in this state for about 100 seconds, then is turned off. This kind of \u003cstrong\u003esensor switch\u003c\/strong\u003e is suitable for making touch-operated bells, buzzers of small toys which operate for a small time and then switch off automatically.\u003c\/p\u003e\n\u003cp\u003eThe input impedance of the trigger is very high and the \u003cstrong\u003etouch sensor switch\u003c\/strong\u003e can be triggered by the voltage induced in the human body. The monostable mode of operation of 555 IC can be explained using a simple touch-sensitive circuit. Here, the timing constant (T) of the monostable timer= 1.1*R2*C2. The \u003cstrong\u003eTouch Sensor Circuit\u003c\/strong\u003e has been configured in monostable mode. A monostable circuit produces a single pulse(for a certain duration determined by the Timing Constant(T)=1.1*R2*C2) when triggered at pin 2.\u003cbr\u003e\u003cbr\u003e\u003c\/p\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 : 15 x 12 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 50\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\/9i1pZheqEOk\" 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\/Bauoj7nuP94\" 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 title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Pjsoq-ZejRM\" 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\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF","offer_id":40708941709493,"sku":"LGZK006","price":129.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/touch-sensor-using-555-timer.jpg?v=1634383268","url":"https:\/\/kitsguru.com\/de\/products\/touch-sensor-using-555-timer","provider":"KitsGuru","version":"1.0","type":"link"}
