The BME680 is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement based on proven sensing principles.
Its small dimensions and its low power consumption enable the integration in battery-powered or frequency-coupled devices, such as handsets or wearables.
BEM680 environmental sensor adopts 12C interface, onboard power supply voltage regulator chip and level signal conversion chip, which has good compatibility and can be directly compatible with 3.3V and 5V systems; SPI interface is reserved for easy expansion.
It is highly integrated and can detect four environmental parameters at the same time. It is an ideal choice for scenarios such as weather stations, smart homes, and the Internet of Things.
