Analog Protocol Sensors
Compatible with ESP32

The list of sensors using Analog protocol for your ESP32 projects, complete with wiring guides and code examples.

Analog signals represent real-world, continuous values—such as temperature, light, sound, or force. Arduino boards typically feature multiple ADC (Analog-to-Digital Converter) pins, and ESP32 boards offer up to 12-bit resolution across several analog channels.

Analog input is key to using sensors like photoresistors, potentiometers, and analog temperature sensors (e.g., LM35). You can read analog values using analogRead() to bring real-world measurements into your microcontroller project.
