BMP180 GY-68 Digital Barometric Pressure Sensor breakout module for Arduino

Description

The BMP180 GY-68 Digital Barometric Sensor Module is a compact and accurate sensor for measuring atmospheric pressure and temperature. It is specifically designed for Arduino and Raspberry Pi boards, making it an ideal choice for various projects. This breakout board supports the BMP180 high-precision digital pressure sensor. The pressure range of the BMP180 is 300-1100hPa.

The BMP180 module also measures temperature with high precision. It provides temperature readings in degrees Celsius (°C) with an accuracy of around ±0.5°C. Connect the module to Arduino or Raspberry Pi using wires or a breadboard to use it. The module usually has four pins: VCC (power supply), GND (ground), SDA (data line), and SCL (clock line), which you connect to the corresponding pins on your microcontroller or single-board computer.

A low current draw of 0.3 uA makes it suitable for battery-powered applications. A calibrated and ready-to-use BMP180 is delivered. Because the device communicates over I2C, we’ve provided optional I2C pull-ups, which can be enabled using the board’s PU (pull-up) jumper.
