Product features

  • UPGRADED - Better than BMP085/BMP180/BMP183, great for all sorts of weather sensing.
  • HIGH PRECISION - Barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0 °C accuracy.
  • LOW POWER CONSUMPTION - Low power consumption of 2.7µA.
  • 3.3V VOLTAGE STABILIZING CIRCUIT - With 3.3V voltage regulator tube for a 5V or 3.3V power.
  • I2C OR SPI INTERFACE - I2C: easy wiring
  • SPI: free of port conflict worry.

Product Description

Introduction
The BMP280 is an absolute barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact 8-pin metal-lid LGA package with a dimension of 2.0 x 2.5 x 0.95m. Its small dimensions and low power consumption of 2.7µ[email protected] allow the implementation in battery-driven devices such as mobile phones, GPS modules or watches. With the I2C and SPI communication, you can apply it in different uses. It’s a best choice for experiments like testing altitude and some projects involving air pressure.
