DIYables Voltage Sensor DC 0-25V for Arduino, ESP32, ESP8266, Raspberry Pi
Click to zoom
Quick Overview
This DIYables DC voltage detection module is designed for voltage measurement purposes, supporting a voltage input range of DC 0V-25V for 5V microcontrollers (e.g., Arduino Uno) and DC 0V-16.5V for 3.3V microcontrollers (e.g., ESP32, ESP8266). The module uses a voltage divider circuit to scale down the input voltage for safe ADC reading.
The sensor requires connecting GND to the negative terminal and VCC to the positive terminal of the DC input interface. For ESP32 users, configure the ADC with 11 dB attenuation to set the voltage reference range to handle up to 3.3V for accurate readings.
Ideal for battery voltage monitoring, power supply measurement, solar panel monitoring, DC power projects, voltage level detection, battery charge monitoring, and any application requiring safe DC voltage measurement with Arduino, ESP32, or ESP8266.
