391

The 391 is a Precision Sensor Module Board for use with measuring barometric pressure and temperature. Because pressure changes with altitude can also use it as an altimeter. The sensor is soldered onto a PCB with a 3.3V regulator, I²C level shifter and pull-up resistors on the I²C pins. The BMP085 is the fully pin- and function compatible successor of the SMD500, a new generation of high precision digital pressure sensors for consumer applications. The universal C-code SMD500/BMP085 (BMP085_SMD500_API) is fully upward compatible to SMD500 and recognizes automatically the device ID. The ultra-low power, low voltage electronics of the BMP085 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 BMP085 offers superior performance. The I²C interface allows for easy system integration with a microcontroller.
