ESP32 BMP180 Air Pressure Sensor Module

The ESP32 BMP180 Air Pressure Sensor Module integrates a BMP180 sensor with the ESP32 microcontroller, enabling precise measurement of atmospheric pressure and temperature. Utilizing I2C communication, it provides accurate altitude data for weather forecasting, altitude tracking, and indoor navigation applications. Integration with ESP32 development environments allows seamless integration into IoT projects and environmental monitoring systems.

Components Needed

Circuit Setup:

Connections:

BMP180 to ESP32:

VCC to 3.3V
