Product Description This product is retiring; quantity limited to stock on hand. BME680 Environmental Sensor Overview: Raise your project’s environmental awareness with the BME680. The Bosch Sensortec BME680 Integrated Environmental Unit combines a gas sensor with air pressure, humidity, and ambient air temperature sensing functions within a single package for high performance air quality measurement. Parallax Inc. places the BME680 on a compact PCB with a 6-pin male header. This capable sensor does not have to be difficult to use. The BME680 is supported by BlocklyProp visual programming as well as C libraries for the Propeller multicore microcontroller. Code for other controllers is available from the Bosch Github repository. BME680 Environmental Sensor Features: Low power, high-performance gas, pressure, temperature, and relative humidity sensor in a single package Detects a broad range of VOCs (Volatile Organic Compounds) Supports I2C, SPI 3-wire, and SPI 4-wire interfaces Overvoltage, reverse polarity and signal contention protection of all signal pins VIN / GND reverse polarity protection Compatible with 3.3 V and 5 V microcontrollers Breadboard-friendly 6-pin header with 0.1” spacing, plus two mounting holes PCB assembled, tested, and completed in Rocklin, California Application Ideas: air quality monitoring Home automation and control Weather forecast Warning system for high temp, low-humidity conditions Context awareness, e.g. skin moisture detection, room change detection Vertical velocity indicator (rise/sink speed) Indoor navigation, e.g. change of floor detection, elevator detection Altitude tracking and calories expenditure for sports activities BME680 Environmental Sensor Key Specifications: Power requirements: 3.3 VDC to 5 VDC; maximum 20 mA Typical current consumption: 3.7 µA at 1 Hz humidity, pressure and temperature 0.09‒12 mA for p/h/T/gas depending on operation mode 0.15 µA in sleep mode Absolute barometric pressure: range 300–1100 hPa; ±0.12 hPa Relative humidity: range, 0–100%; ±3% Temperature: range -40 to 85 °C; resolution 0.01°C, ±0.5°C typical Gas sensor resolution: 0.08% typical Communication: I2C (100 or 400 kHz) or SPI (3 and 4 wire, up to 10 MHz) Operating temperature: -40 to 185 °F (-40 to 85 °C), Operating environment: 0‒100% r.H., 300‒1100 hPa Form factor: 6-pin male header with 0.1″ spacing PCB dimensions: 20 x 18 mm Mounting holes: Two holes suitable for #3 UNC (M2.5) hardware
