Description
Have you ever wished to build your own weather station with Arduino? Then you might be interested in the BMP180 board featuring the precise sensor from Bosch. The digital sensor on the board accurately measures changes in barometric pressure and temperature. It uses the piezoresistive effect for data collection. Since pressure depends on altitude, the sensor can measure this as well. The very low operating current and voltage allow the use of these types of sensors in many modern devices where low power consumption is important.
The design is intended for a voltage of 5V, with an embedded regulator for 3.3V. The operating current of the board is very low, only 5 µA. The sensor uses I2C communication, and the I2C address is 0x77. With easyC, soldering and distinguishing between SDA and SCL are not necessary. The sensor has EEPROM memory with calibration data. Pressure is measured in increments of 1 hPa (=0.01 hPa = 0.01 mbar) and 0.1 °C for temperature.
