BMP180 Digital pressure sensor

This pressure sensor is a BMP-180 based digital barometric pressure sensor module and is functional compatible with older BMP-085 digital pressure sensor with less power consumption smaller in size and more accurate. BMP180 combines barometric pressure, temperature and altitude. The I2C allows easy interface with any microcontroller. On board 3.3V LDO regulator makes this board fully 5V supply compatible. BMP-180 can measure pressure range from 300 to 1100hPa (+9000m to -500m relating to sea level) with an accuracy down to 0.02hPa (0.17m) in advance resolution mode. BMP-180 is an improved replacement for BMP-085 sensor. BMP-180 uses piezo-resistive technology for high accuracy, linearity, EMC robustness and stability for a longer period of time.

  • Supply Voltage:1.8V to 3.6V
  • Low power consumption:0.5uA at 1Hz
  • I2C interface
  • Max I2C Speed: 3.5Mhz
  • Very low noise:up to 0.02hPa (17cm)
  • Pressure Range: 300hPa to 1100hPa (+9000m to -500m)

DHT11 Library:

https://github.com/adafruit/DHT-sensor-library

CIRCUIT CONNECTION

  • Connect Arduino Mega 5v pin to positive rail on breadboard(make a positive rail by giving positive supply on breadboard) and ground to negative rail(make a negative rail by giving negative supply on breadboard)
  • Connect DHT11 ground pin to negative rail on breadboard and positive to the positive rail on breadboard
  • Connect DHT11 data pin to D16 pin of arduino mega
  • Connect BMP180 Vcc pin to positive rail on breadboard and BMP180 ground pin to negative rail on breadboard and BMP180 SDA to mega SDA and BMP180 SCL to mega SCL pin.

WORKING

Welcome to this Arduino Weather Station project with a BMP180 and a DHT11 sensor. The BMP180 sensor in order to measure barometric pressure in real time so we can predict the coming weather.

As you can see in the display we have temperature humidity and pressure in Pascals.

This little sensor here has embedded a very accurate temperature sensor as well so we are not measuring temperature with the DHT11 which is not accurate we are measuring temperature with this sensor and we display it in the display.
