    Bosch BME680 Sensor Specs

    • Digital interface I²C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz)
    • Operating range -40 - +85°C, 0-100 % r.H., 300-1100 hPa
    • Humidity, Pressure, Gas sensor can be independently enabled / disabled
    • RoHS compliant, halogen-free, MSL1

    Pressure Sensor

    • RMS Noise 0.12 Pa, equiv. to 1.7 cm
    • Offset temperature coefficient ±1.3 Pa/K, equiv. to ±10.9 cm at 1 °C temperature change

    Humidity Sensor

    • Response time 8 s
    • Accuracy tolerance ±3 % relative humidity
    • Hysteresis ±1.5% relative humidity

    Gas Sensor

    • Response time < 1s (for new sensors)
    • Power consumption < 0.1mA in ultra-low power mode
    • Output data processing: direct index for air quality (IAQ) output

      TinyDuino Power Requirements

      • Voltage: 3.0V - 5.5V 
      • Current:
        • 2.1 µA @ 1 Hz humidity and temperature
        • 3.1 µA @ 1 Hz pressure and temperature
        • 3.7 µA @ 1 Hz humidity, pressure, and temperature
        • 0.15 µA in sleep mode
        • Due to the low current, this board can be run using the TinyDuino coin cell option.

      Pins Used

      • A5/SCL - I²C Serial Clock line
      • A4/SDA - I²C Serial Data line

      Dimensions

      • 10mm x 10mm (.394 inches x .394 inches)
      • Max Height (from the lower bottom of Wireling to upper top Wireling Connector): 3.70mm (0.15 inches)
      • Weight: 1 gram (.04 ounces)
      • You can also use this Wireling without the TinyDuino – modifying the connecting cable by removing the opposite connector and stripping/tinning the wires, you can solder the connector cable to any other microcontroller board of your choice!
