{"product_id":"seismic-sensor-circuit","title":"Seismic Sensor Circuit","description":"This \u003cstrong\u003ecircuit simulates\u003c\/strong\u003e a Piezoelectric sensor to detect vibrations\/sounds. It is very sensitive and can detect vibrations caused by the movement of animals or human beings. This \u003cstrong\u003eSeismic Sensor\u003c\/strong\u003e can be used to monitor protected areas to restrict the entry of unwanted persons or animals. This high output is used to trigger the switching transistor, which triggers mono-stable IC 555. The timing period of IC 555 is determined by resistance and capacitance value. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSeismic Sensor Circuit\u003c\/strong\u003e IC TLO71 is wired as a differential amplifier with both its inverting and non-inverting inputs tied to the negative rail through a resistive network comprising both the inputs receive almost equal voltages, which keeps the output low. When the piezo element is disturbed (by even a slight movement), it discharges the stored charge. This alters the voltage level at the inputs of IC and the output momentarily swings high as indicated by a green LED.\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=\"Seismic-Sensor-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Seismic-Sensor.jpg?v=1633519721\" 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 width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/umh0zNFxde4\" 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\/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":40708890919093,"sku":"LGKT125","price":399.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708890951861,"sku":"LGKT125_R","price":549.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/seismic-sensor-arduino.jpg?v=1633520055","url":"https:\/\/kitsguru.com\/de\/products\/seismic-sensor-circuit","provider":"KitsGuru","version":"1.0","type":"link"}
