Temperature, Pressure, Humidity, and VOC BME680 Wireling
DESCRIPTION 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. New to Wirelings? Check out the Wireling Overview! Note* 5-Pin Wireling cables not included and sold separately. TECH SPECS 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) 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!
