Linkit One and BMP180 example


The bmp180 from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins. The BMP180 replaces the BMP085.


  • Pressure sensing range: 300-1100 hPa (9000m to -500m above sea level)
  • Up to 0.03hPa / 0.25m resolution
  • -40 to +85°C operational range, +-2°C temperature accuracy

Here is a breakout which makes it easy to use the sensor, link at the bottom.





You will need the Adafruit BMP085 library for this example, you can either download it or use the library manager in newer Arduino IDEs.

In this example I am only looking at the temperature and pressure but there are other functions in the library

#include <Wire.h>
#include <Adafruit_BMP085.h>
Adafruit_BMP085 bmp;
void setup() 
  //Wire.begin (4, 5);
  if (!bmp.begin()) 
    Serial.println("Could not find BMP180 or BMP085 sensor at 0x77");
    while (1) {}
void loop() 
  Serial.print("Temperature = ");
  Serial.println(" Celsius");
  Serial.print("Pressure = ");
  Serial.println(" Pascal");


Open the Serial monitor or using a terminal emulator and you should see output like this
Temperature = 23.80 Celsius
Pressure = 101660 Pascal

Temperature = 23.70 Celsius
Pressure = 101652 Pascal

Temperature = 23.70 Celsius
Pressure = 101644 Pascal

Temperature = 23.50 Celsius
Pressure = 101652 Pascal

Temperature = 23.50 Celsius
Pressure = 101651 Pascal

Temperature = 23.40 Celsius
Pressure = 101650 Pascal
