The BMP180 is the function compatible successor of the BMP085, a new generation of high precision digital pressure sensors for consumer applications. The ultra-low power, low voltage electronics of the BMP180 is optimized for use in mobile phones, PDAs, GPS navigation devices and outdoor equipment. With a low altitude noise of merely 0.25m at fast conversion time, the BMP180 offers superior performance. The I2C interface allows for easy system integration with a microcontroller. The BMP180 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability.

The module (HCMODU0101) measures a tiny 13mm x 10mm and contains the 3.3V regulator allowing the module to be safely powered from a 5V source. Solder terminal for power and I2C interface are provided with 10K pullups for the I2C data and clock pins.

Arduino users:

To make using this module with your Arduino as easy as possible we have written an exclusive library (HCBMP180). This library can be downloaded from the software section of our support forum here:

viewtopic.php?f=58&t=2019

The library will allow you to obtain calibrated temperature and pressure measurements from the module. Additionally it can also be used to get absolute altitude, relative altitude, and pressure at sea level measurements.
