BME680 Temperature, Humidity, Pressure and Gas Sensor

BME680 is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement based on proven sensing principles. Its small dimensions and its low power consumption enable the integration in battery-powered or frequency-coupled devices, such as handsets or wearable.

Specifications:

• Interface:  I²C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz)
• Supply Voltage:
  • VDD main supply voltage range: 1.71 V to 3.6 V
  • VDDIO interface voltage range: 1.2 V to 3.6 V
• Current Consumption
  • 2.1 μA at 1 Hz humidity and temperature
  • 3.1 μA at 1 Hz pressure and temperature
  • 3.7 μA at 1 Hz humidity, pressure and temperature
  • 0.09‒12 mA for p/h/T/gas depending on operation mode
  • 0.15 μA in sleep mode
• Operating Range: -40°C to +85°C, 0‒100% r.H., 300‒1100 hPa
• Individual Humidity, pressure and gas sensors can be independently enabled/disabled
• Compatible with 3.3V and 5V Systems
• Dimension: 16.3 x 18.7mm
• Weight: 1.3g

Typical applications :

• Indoor air quality
• Home automation and control
• Internet of things
