Hi, I buyed a BMP 180Barometric Pressure/Temperature/Altitude Sensor- 5V ready to use with the Arduino Uno. I installed all the libraries for the BMP085 and Unified sensor library, wires are well connected and code runs well but when I opened the serial monitor a message appear: BMP 085 not detected, check wires or I2C ADDR. BMP 180 is supposed to runs with the same code and libraries for BMP 085 but Arduino Uno is not detected the sensor. Help is appreciated.
Try the i2c_scanner until it is detected : Arduino Playground - I2cScanner
You could make a photo of your wiring.
Do you have a cheap clone Uno board ? Sometimes they have missing connections or shortcuts on the board.
