    MIKROE Environment 3 Click is a compact add-on board that contains a four-in-one environmental measurement solution. This board features BME688, a first gas sensor with Artificial Intelligence (AI), and integrated high-linearity/high-accuracy pressure, humidity, and temperature sensors from Bosch Sensortech. The BME688 can detect Volatile Organic Compounds (VOCs), Volatile Sulfur Compounds (VSCs), and other gases such as carbon monoxide and hydrogen in part per billion (ppb) range. It provides absolute temperature accuracy, typical of ±1°C, and best performance when operated within the pressure, temperature, and humidity range of 300-110hPa, 0-65°C, and 10-90%RH. Also, it comes with a configurable host interface that supports both SPI and I2C serial communication. This Click board™ is suitable for indoor and outdoor air quality measurement, detection of unusual gases and smells, and various temperature and humidity-related applications.

    Environment 3 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    Environment 3 Click as its foundation uses the BME688, air quality MEMS sensor that combines gas, humidity, temperature, and barometric pressure sensing from Bosch Sensortech. The BME688 combines reliable high-precision sensors with wide-ranging gas detection and innovative AI capabilities, enabling users to rapidly develop various applications to improve well-being, lifestyle, and sustainability. It offers reduced power consumption, improved accuracy specifications, and a configurable host interface for the fastest data transfer. It covers extended operating pressure, humidity, and temperature ranges from 300-1100hPa, 0-100%RH and from -40°C to +85°C with the accuracy of ±3%RH and ±0.5°C.

    The BME688 supports a full suite of operational modes, which provides vast flexibility in optimizing the device for power consumption, resolution, and filter performance. Additionally, it also has a gas scanner function; it can detect Volatile Organic Compounds (VOCs), Volatile Sulfur Compounds (VSCs), and other gases such as carbon monoxide and hydrogen in part per billion (ppb) range. In standard configuration, the presence of VSCs is being detected as an indicator for, e.g., bacteria growth, where the gas scanner can be customized for sensitivity, selectivity, data rate, and power consumption.

    Based on its main features listed above, this Click board is the best choice for indoor and outdoor air quality measurement applications, detection of unusual gases that might indicate leakage or fire, early detection of odors and bad smells, and other various temperature and humidity-related applications.

    Environment 3 Click allows using both I2C and SPI interfaces. The selection can be made by positioning SMD jumpers labeled as COMM SEL to an appropriate position. Note that all the jumpers' positions must be on the same side, or the Click board™ may become unresponsive. While the I2C interface is selected, the BME688 allows choosing the least significant bit (LSB) of its I2C peripheral address using the SMD jumper labeled as ADDR SEL to an appropriate position marked as 0 or 1.

    This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

    BME AI-STUDIO TOOL Bosch Sensortec’s tool for the BME688 sensor, such as the BME AI-Studio Software, allows users to develop, verify, and deploy custom gas classification use-cases. It enables sensor configuration, data analysis, training, and optimization of application-specific solutions. The BME688 detects gases by measuring their unique electronic fingerprint and therefore distinguish different gas compositions, enabling a broad spectrum of new applications. Thus, the BME AI-Studio tool allows customers to train the BME688 gas scanner feature on their specific applications, like home appliances, IoT, or Smart Home solutions.
