BME280, the precision sensor from Bosch, is soldered onto PCB. Not only the pressure and the temperature, this sensor can measure humidity. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface.

Specifications:

• Supply Voltage: 1.8 - 5 V DC
• Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz)

Operational range:

• Temperature: -40 to +85°C
• Humidity: 0-100%
• Pressure: 300-1100 hPa

Resolution:

• Temperature: 0.01°C
• Humidity: 0.008%
• Pressure: 0.18Pa

Accuracy:

• Temperature: +-1°C
• Humidity: +-3%
• Pressure: +-1Pa
