The project offers an economical solution for positive and negative voltage detection. The circuit consists of two comparator channels each with hysteresis, a unique Mode Select Input for channel programming, a pinned out 2.54 V reference, and two open collector outputs installed with LED for visual alert for under-voltage and over-voltage situations. The project is configured for a 5V supply by default. It provides a visual indication when supply is lower the 5V and over 5V. Yellow LED indicates undervoltage and Red LED indicates overvoltage. Trimmer potentiometers PR1 and PR2 were provided to adjust the Undervoltage and Overvoltage range. Both inputs can be used as independent or combined (Single Input)\u003c\/p\u003e\n\u003cdiv class=\"simple-alert-boxes sab_info sab_normal\"\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe board is configured to detect Undervoltage and Overvoltage for 5V Supply, however, it provides the user with multiple choices and extensive flexibility for different applications circuits and configurations.

Set the Adjustable power supply to 4.5V DC and connect it to Pin 3 or Pin5 of the CN1 Connector.  Turn the PR1 trimmer potentiometer carefully so the Yellow LED glows, now set the adjustable power supply to output 5.5V and turn the trimmer potentiometer PR2 such Red LED D3 should glow. Now, the project is configured and ready to be used. It is set to detect and indicate undervoltage of 4.5V and Over voltage of 5.5V. Connector CN2 can help for microcontroller interface, Output 1 and Output 2 Normally goes High or low when under\/over voltage conditions are detected.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower Supply 5V DC (Range 5 to 12V DC)\u003c\/li\u003e\n\u003cli\u003eYellow LED for Under Voltage detection\u003c\/li\u003e\n\u003cli\u003eConfigured for 5V Detection\u003c\/li\u003e\n\u003cli\u003eRed LED for Overvoltage Detection\u003c\/li\u003e\n\u003cli\u003eProvides Visual Alerts when Under-Over Voltage is Detected at input 1 and Input 2\u003c\/li\u003e\n\u003cli\u003eOutput 1 and Output 2 for Micro-Controller Interface\u003c\/li\u003e\n\u003cli\u003eLEDs can be Replaced with Audible Buzzer (Low Current Buzzer 10mA maximum)\u003c\/li\u003e\n\u003cli\u003e4 X 2.5 MM Mounting Holes\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 53.66 x 24.92mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47196807495852,"sku":"B112","price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/B112A.jpg?v=1789281203","url":"https:\/\/dotfry.com\/products\/under-voltage-and-over-voltage-monitor-for-5v","provider":"dotfry","version":"1.0","type":"link"}
