Mô tả :
This BME680 environmental sensor contains temperature, humidity, barometric pressure, and Volatile Organic Compound (VOC) gas sensing capabilities in a single package.
Compared to the BME280, the BME680 has lower power consumption and is well-suited for mobile applications. This precision sensor from Bosch can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. As the pressure measurements are highly accurate, you can also use it as an altimeter with ±1 meter or better accuracy.
The BME680 features a Metal Oxide (MOX) sensor. The onboard heated metal oxide changes resistance based on the volatile organic compounds in the air. As such, it can be used to detect gasses & alcohols such as Ethanol, Alcohol and Carbon Monoxide. The sensor can be used to be used in projects requiring air quality.
This BME680 module has a built-in XC6206 3.3V voltage regulator, making it capable of using either 3.3V and 5V or 5V input power without modification.
The BME680 sensor is highly versatile and can be interfaced with either 3.3V or 5V compatible microcontrollers such as the ESP32, Teensy or Arduino microcontrollers. No logic level shifter is required, it uses an embedded 2N7002DW logic level shifter module.
Communication is done via the SPI or I2C bus. I2C is most recommended for a simple, 2-wire configuration and is addressable, meaning that 2 BME680 sensors and many other I2C compatible sensors can be connected to the same microcontroller I2C bus, increasing versatility.
Uses:
- - Air quality measurement devices
- - DIY weather station
- - Altitude mapping
Please Note:
- - Like all VOC gas sensor modules, measuring against a known source is recommended for accuracy. (Only for the VOC sensor readings). The VOC readout will give you one value, with overall VOC content, but it cannot differentiate gasses or alcohols.
- - For VOC readings, we recommend that you run this sensor for 48 hours initially to “burn it in”, and then 30 minutes in the desired mode every time the sensor is in use. This is because the sensitivity levels of the sensor will change during early use, and the resistance will slowly rise over time as the MOX warms up to its baseline reading.
