3-Wire Protocol SensorsCompatible with ESP32
The list of sensors using 3-Wire protocol for your ESP32 projects, complete with wiring guides and code examples.
The 3-Wire protocol is a simplified serial communication method that typically includes Data, Clock, and Ground lines. It's commonly used in older sensors or basic shift register-based modules.
While less common than SPI or I2C, the 3-wire configuration is easy to implement using standard digitalRead() and digitalWrite() functions on ESP32 and Arduino. It’s especially useful for driving LED displays and simple binary interfaces.
