Pressure, Temperature & Altitude Sensor (BMP085)

A great low cost barometric pressure sensor. Use it to monitor weather changes, or altitude (as pressure varies with altitude). It also includes an on board temperature sensor helping make it a great sensor for overall environmental monitoring. It also includes an on board 3.3v regulator and level shifter meaning it is compatible with the Arduino's 5v logic. Finally it is i2c (digital) meaning the readings are fast and reliable.

Features:

• Three in one sensor (pressure, altitude temperature)
• On board support circutry means wiring is easy (only 4 wires)
• Great included library (means using it is super simple)

Technical Details:

• Pressure Range: 300 - 1100 hPa (9000m to -500m above sea level)
• Dimensions: 20.32 x 20.32 mm (0.8" x 0.8")
• Operating Voltage: 3.3-5v
• Logic Level: 3-5v compliant
• Communication: i2c
