- DC Voltage Detection Module is designed for voltage detection or measurement purposes.
- It supports a voltage input range of DC 0V-25V for 5V micro-controllers (e.g., Arduino Uno) and DC 0V-16.5V for 3.3V micro-controllers (e.g., ESP32, ESP8266).
- The DC input interface requires connecting GND to the negative and VCC to the positive terminals.
- Tutorials for Arduino, ESP32, ESP8266 are provided
-
- ...NOTE
- If you are using the ESP32, you need to configure the ADC with 11 dB attenuation to set the voltage reference range to handle up to 3.3V.
