BMP180 Pressure Sensor Module
BMP180 Digital Barometric Sensor Module compatible with Arduino will Measure the absolute pressure of the environment using a digital barometer such as this has some interesting applications.
By converting the pressure measured into altitude, you have a reliable sensor for determining the height of your robot, plane or projectile! Using a sensor as capable as the BMP180 you can achieve an accuracy of 1m, with the noise of only 17cm in ultra-high resolution noise.
The device will operate at the only 0.3uA meaning low current draw for battery-powered applications. The BMP180 comes fully calibrated and ready to use. As the device operates over I2C we’ve added optional I2C pull-ups that can be enabled using the PU (pull up) jumper on the board for your convenience and ease during breadboarding.
Using I2C, the device provides pressure and temperature as 16bit values, which are used along with calibration data within the device are used to provide a temperature compensated altitude calculation.\

Frequently Asked Questions
1. How does a BMP180 sensor work?
- BMP180 is an atmospheric pressure sensor. The BMP180 sensor primarily measures atmospheric or biometric pressure. The air pressure sensor's operation is very simple; it is based on the weight of air. Because the air around us has a specific weight and a specific pressure.
2. How do I connect my BMP180 to Arduino?
- Connections are straightforward. Begin by connecting the VIN pin to the Arduino's 5V output and the GND pin to ground. We're still working with the pins used for I2C communication. It should be noted that each Arduino Board has different I2C pins that must be connected correctly.
3. How does a barometric pressure sensor work?
- This type of barometric pressure sensor makes use of an aneroid cell, which expands and contracts in response to changes in atmospheric pressure. This movement causes the levers to amplify, resulting in display pointers on the front display indicating the pressure reading.
4. How do I connect my BMP180 to NodeMCU?
- Connecting the BMP180 Barometric Pressure Sensor to the NodeMCU ESP8266 is easy. The connection is straightforward. Connect the Nodemcu ESP8266's VIN pin to the 3.3V voltage pin, GND to ground, SCL to D1 and SDA to D2.
