Temperature, Pressure, Humidity, and VOC BME680 Wireling

This Wireling lets you measure Temperature, Pressure, Humidity, and Volatile Organic Compounds (VOCs) via the BME680. This sensor is an upgrade from the BME280 that measures Pressure and Humidity.

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!
