Design with Voltage Sensor DC 25V in Cirkit DesignerThe Voltage Sensor DC 25V is an electronic component designed to measure DC voltage levels up to 25 volts. It is commonly used in various applications such as battery monitoring, solar panel voltage measurement, and in any system where voltage level monitoring is crucial. This sensor is particularly useful in microcontroller-based projects, where it can be interfaced with platforms like Arduino to read and process voltage levels in real-time.
This circuit monitors the voltage of a 18650 Li-Ion battery using a Voltage Sensor DC 25V and an ESP32 Devkit V1 microcontroller. The voltage sensor is powered by the battery and its output is read by the ESP32, which can process or transmit the voltage data for further use.

Q: Can I measure voltages higher than 25V with this sensor? A: No, applying more than 25V to the sensor can damage it. Use a voltage divider to measure higher voltages.
Q: How can I improve the accuracy of the sensor? A: Calibration with a known voltage source and averaging multiple readings can improve accuracy.
Q: Is it possible to use this sensor with a 3.3V microcontroller? A: Yes, but you will need to use a level shifter or voltage divider to ensure the output voltage is within the microcontroller's input voltage range.
