Description
This is a simple breakout board for the BMP085 high-precision, low-power barometric pressure sensor from DFRobot. The BMP085 offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.03 hPa. It’s based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long-term stability. This sensor supports a voltage supply between 1.8 and 3.6 VDC. It is designed to be connected directly to a micro-controller via the I2C bus

 

This breadboard-friendly board breaks out all pins of the BMP085 to a 6-pin 0.1″ pitch header. The analogue and digital supplies (VDDD and VDDA) of the BMP085 are tied together and broken out into a single pin. We’ve also put two 4.7k pull-up resistors on the I2C lines.

 

This NodeMCU IoT project is a simple demonstration on how to send sensor data to the Internet.
