Circuitrocks Altimeter Barometric Pressure Altitude Temperature MPL3115A2 I2C Sensor

Circuitrocks. TECHNICAL DETAILS. Dimensions: 18mm x 19mm x 2mm. 7 x. 8 x. 1". Weight: 1.2g. Vin: 3 to 5.5 VDC. Logic: 3 to 5V compliant. Pressure sensing range: 50-110 kPa up to 10Km altitude). 1.5 Pa 0.3 m altitude resolution. This board/chip uses I2C7-bit address 0x60. This pressure sensor from Freescale is a great low-cost sensing solution for precision measurement of barometric pressure and altitude. The MPL3115A2 has a typical 1.5 Pascal resolution, which can resolve altitude at 0.3 meters compare to the BMP180 which can do 0.17m). It has some upsides compared to the BMP180, such as interrupt outputs for ultra-low power usage, and its also a heck of a lot easier to read altitude with a built in altimeter calculation-no calibration reading and calculating required. As a bonus, there's even a fairly good temperature sensor with 1C typical accuracy 3C max). This chip likes to be used with 2-3.6V power and logic voltages, so we placed it on a breakout with a 3V regulator and logic lev
