A successor of the BMP085, The BMP180 is a new generation of high precision digital pressure sensors for consumer applications. It has ultra-low power consumption, very low voltage electronics of the BMP180 is optimized for uses in mobile phones, PDAs, GPS navigation devices and outdoor equipment. BMP180 offers superior performance With a low altitude noise of merely 0.25m at fast conversion time, The I2C interface allows very 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 pull-ups for the I2C data and clock pins.
