Introducing the BME680 Temperature, Humidity, Pressure, and Gas Sensor Module
Experience the ultimate environmental sensing solution with the highly anticipated BME680 by Bosch, all conveniently packed into a compact module. This remarkable sensor combines temperature, humidity, barometric pressure, and VOC gas sensing capabilities, accessible over SPI or I2C interfaces, and all at an exceptional value.
Similar to its predecessors, the BME280 and BMP280, this precision-engineered sensor from Bosch offers impressive accuracy. It can precisely measure humidity with a margin of ±3%, barometric pressure with an absolute accuracy of ±1 hPa, and temperature with an impressive ±1.0°C accuracy. The precision of its pressure measurements also allows it to function as an altimeter with an accuracy of ±1 meter or better, leveraging altitude variations.
What sets the BME680 apart is its integration of a small MOX sensor. This specialized sensor detects changes in resistance based on the presence of volatile organic compounds (VOC) in the surrounding air. As a result, it can effectively identify gases and alcohols such as Ethanol, Alcohol, and Carbon Monoxide, facilitating air quality assessments. While it provides an overall VOC content reading, it’s important to note that it cannot differentiate between various gases or alcohols.
Keep in mind that, like all VOC/gas sensors, the BME680 exhibits variability, requiring calibration against known sources for precise measurements. However, for general environmental sensing purposes, it provides valuable insights into trends and comparisons. We recommend an initial “burn-in” period of 48 hours upon receiving the sensor, followed by 30-minute sessions in the desired mode each time the sensor is employed. This initial usage is crucial as the sensor’s sensitivity levels evolve and the MOX gradually warms up to its baseline reading over time.
For your convenience, we’ve expertly placed the sensor on a PCB equipped with a 3.3V regulator and level shifting capabilities. This design ensures seamless compatibility with your preferred 3.3V or 5V microcontroller, streamlining integration into your projects.
