Temperature, Pressure, Humidity, and VOC BME680 Wireling

$ 19.95

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.

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)

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!
