25V Voltage Sensor
A complete guide to the 25V Voltage Sensor, including pinout, working principle, applications, and more.
25V Voltage Sensor Overview
The **25V Voltage Sensor** is a simple and effective sensor used to measure voltages up to 25V. It is commonly used in various electronic projects where the monitoring of voltage levels is essential. It can be interfaced with microcontrollers such as Arduino or ESP32 for real-time voltage monitoring and control. The sensor typically uses a resistive voltage divider to scale the input voltage and provide a corresponding output that can be read by a microcontroller’s analog input pin.
Pinout of 25V Voltage Sensor
The 25V Voltage Sensor module has a few important pins for operation. Below is the pinout of the sensor:
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | VCC | Power supply pin, typically connected to +5V or +3.3V, depending on the microcontroller being used. |
| 2 | GND | Ground pin, connected to the ground of the system. |
| 3 | Analog Output | Output pin that provides a voltage proportional to the input voltage, typically connected to an ADC pin of the microcontroller. |
Working Principle of 25V Voltage Sensor
The **25V Voltage Sensor** works based on the principle of voltage division. The sensor consists of a resistive voltage divider circuit that reduces the input voltage to a level that can be safely read by the microcontroller’s ADC (Analog to Digital Converter). When a voltage is applied to the sensor’s input, the resistor network divides the voltage in a way that the output voltage corresponds to the input voltage in a known ratio. This allows the sensor to output a voltage proportional to the input voltage, which can then be measured and processed by the microcontroller.
