IoT Weather Station BMP180

Updated: Jul 2, 2021

In this project, To interface BMP180 Barometric Pressure Sensor with NodeMCU ESP8266 12E. This sensor are fairly simple to use, pre-calibrated and don’t require extra components so you can start measuring temperature, pressure & altitude.

BMP180 Chip

BMP180 can measure barometric pressure from 300 to 1100 hPa (9000m to -500m above sea level), and temperature from -40°C to 85°C with ±1.0°C accuracy.The pressure measurements are so precise (low altitude noise of 0.25m), you can even use it as an altimeter with ±1 meter accuracy.
