T5403 Barometric Sensor (300 to 1100hPa)
This is the T5403 breakout board, a fully calibrated barometric pressure sensor with an I2C interface. The T5403 sensor measures the absolute pressure of the air around. This pressure varies with both the weather and altitude. Depending on how you interpret the data, you can monitor changes in the weather, measure altitude, or any other tasks that require an accurate pressure reading.
