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.
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. 
Product code: HCMODU0101
Power supply: 5V
Interface: I2C
Pressure accuracy (hPa): -4.0 to +2.0
Pressure resolution (hPa): 0.01
Temperature resolution (oC): 0.1
Module dimensions: 13mm x 10mm
Raspberry Pi users:
For Raspberry Pi uses we have tested this module with the free Cayenne cloud based IoT software platform. Simply connect the module to your Raspberry Pi as shown below and use the Cayenne software platform to get remote temperature and pressure readings without writing a single line of code.
