This module includes the component BME280 that is translated into a digital signal.
The equipment uses the two I2C and SPI interfaces. The BME280 does not allow the module to be used as an altimeter as opposed to its successor BMP280.
Its 5-pin straight connector allows easy connection to other electronic boards. BME280 Digital Temperature Humidity Barometric Pressure Module features:
- Interfaces:
- I2C (up to 3.4 MHz)
- SPI (up to 10 MHz)
- Supply voltage: 1.8-5VDC
- Module operating range:
- Temperature: -40ºC to + 85ºC
- Humidity: 0-100%
- Pressure: 300-1100 hPa
- Resolution of the measures:
- Temperature: 0.01ºC
- Humidity: 0.008%
- Pressure: 0. 18Pa
- Accuracy of the measures:
- Temperature: +/>

This module includes the BMP280 component that converts atmospheric pressure, temperature and humidity with high precision into a digital signal.
The equipment uses the two I2C and SPI interfaces. The very good measurements made by the BMP280 allows the module to be used as an altimeter.
