The BME680 is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement based on proven sensing principles. BEM680 environmental sensor adopts I2C interface, onboard power supply voltage regulator chip and level signal conversion chip, good compatibility, can be directly compatible with 3.3V and 5V systems, reserved SPI interface, convenient for expansion. Typical applications:Indoor air quality. Home automation and control. Internet of things. Weather forecast. GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection). Indoor navigation (change of floor detection, elevator detection). Outdoor navigation, leisure and sports applications. Vertical velocity indication (rise/sink speed) Target Devices:Handsets such as mobile phones, tablet PCs, GPS devices. Wearables. Home weather stations. Smart watches. Navigation systems. Gaming, e.g. flying toys. IOT device Working voltage: 1.7V3.6V Working temperature: -40 ℃ ~ + 85 ℃ Communication interface: 12C (up to 3.4 MHz) and SPI (3 and 4 wires, up to 10 MHz) Humidity, pressure and gas sensors can be enabled / disabled individually The current consumption at 1 Hz humidity and temperature is 2.1 LA, the current consumption at 1 Hz pressure and temperature is 3.1 LA, and the current consumption at 1 Hz humidity, pressure and temperature is 3.7 LA Gas sensor parameters: response time (33-63%) Less than 1s (for sensors) power consumption in ultra-low power mode Less than 0.1 mA output data processing direct indoor air quality (IAQ) index output humidity sensor parameters: response time (0 -83%) ~ 8s Accuracy tolerance ± 396r ..
