Design with Voltage Sensor in Cirkit DesignerA voltage sensor is an electronic device that measures the electrical potential difference between two points in an electrical circuit. It is essential for monitoring voltage levels to ensure the stability and safety of electrical systems. Voltage sensors are commonly used in a variety of applications, including battery monitoring, energy management systems, and in various types of electronic projects where voltage level detection is required.
This circuit is a sensor interface system powered by a 9V battery, featuring an Arduino Mega 2560 microcontroller and an Adafruit DS1841 digital potentiometer. The circuit includes resistors and capacitors for signal conditioning, with the Arduino handling data acquisition and communication via I2C with the DS1841.

This circuit is designed to monitor voltage levels from two 240V power sources using a pair of voltage sensors connected to an Arduino UNO. The Arduino reads the sensor outputs and, if a voltage higher than 10V is detected, it uses a SIM800L GSM module to send an SMS alert. The system is powered by a Polymer Lithium Ion Battery, and resistors are used for voltage level shifting for the SIM800L communication with the Arduino.

Q: Can I measure AC voltage with this sensor? A: No, this sensor is designed for DC voltage measurements only.
Q: What is the maximum voltage I can measure with this sensor? A: It depends on the model of the voltage sensor. Always refer to the technical specifications for the maximum input voltage.
Q: How can I measure voltages higher than the sensor's range? A: You can use a voltage divider to step down the voltage to a level that is within the sensor's range. Remember to account for this in your calculations.
Q: How do I interpret the analog output from the sensor? A: The analog output is proportional to the input voltage. You will need to convert the analog reading to a voltage using the ADC resolution of your microcontroller.
