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

Technical Specifications:

Bosch BME680 Sensor Specifications:

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)

Notes:

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!
