This is a breakout board for the Bosch BMP180 high-precision, low-power digital barometer. The BMP180 offers a pressure measuring range of 300 to 1100 hPa with an accuracy down to 0.02 hPa in advanced resolution mode. Itâ€™s based on piezo-resistive technology for high accuracy, ruggedness and long term stability. These come factory-calibrated, with the calibration coefficients already stored in ROM. What makes this sensor great is that it is nearly identical to its former rev, the BMP085! This breadboard-friendly board breaks out every pin to a 5-pin 0.1" pitch header. VCC can be from 1.8V to 3.6V and is I/O lines are 5V tolerant; we typically run it on a clean, regulated 3.3V supply. The analog and digital supplies (VDDD and VDDA) are tied to a single header pin, but are separately decoupled. It connects to a microcontroller via IÂ˛C bus (also known as TWI, or on the Arduino, the â€śWireâ€ť library).Features:Digital two wire (IÂ˛C, TWI, â€śWireâ€ť) interfaceWide barometric pressure rangeFlexible supply voltage range (1.8V to 3.6V)Ultra-low power consumptionLow noise measurementsFactory-calibratedIncludes temperature sensorLow-profile with a small footprintDocuments:SchematicEagle FilesDatasheet (BMP180)Quickstart GuideGitHub
