{"product_id":"low-under-voltage-protection-alarm","title":"Low\/Under Voltage Protection Alarm","description":"The main purpose of making this \u003cstrong\u003eVoltage Protection Alarm Project\u003c\/strong\u003e is that if a battery is discharged, then we do not know that the battery is discharged, if the battery drops below a fixed voltage, a red led will light up and a buzzer will sound at the same time. This \u003cstrong\u003eLow\/Under Voltage Protection system\u003c\/strong\u003e will work for under-voltage only, it will not work for over-voltage. Through this circuit, we can only monitor the under-voltage of 9 and 12 volt DC batteries.\u003cbr\u003e\u003cbr\u003eThis \u003cstrong\u003eLow\/Under Voltage Protection Kit\u003c\/strong\u003e is suitable for a 9V and 12V battery, when the battery voltage is normal, it will not alarm. When the battery is over-discharged (less than 10V for 12 volts battery) or (less than 8V for 9 volts battery) in that condition the led will light up and the buzzer will ring along with it. In this, we have used some simple components like LM358 IC, buzzer, led, diode and resistance.\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=\"Low-Under-Voltage-Protection-Alarm-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Low-Under-Voltage-Protection-Alarm.jpg?v=1633514697\" 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\/cl_U5-JagHU\" 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\/6rmErwU5E-k\" 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 title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" 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":40708891443381,"sku":"LGKT140","price":349.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708891476149,"sku":"LGKT140_R","price":499.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/low-under-voltage-protection-alarm.jpg?v=1633514990","url":"https:\/\/kitsguru.com\/fr\/products\/low-under-voltage-protection-alarm","provider":"KitsGuru","version":"1.0","type":"link"}
