DFRobot Environmental Module (CCS811+BME280) Features high accuracy, I2C interface, and fast measurement Build up a simple environmental monitor station Short preheat time, low power consumption Fast response, highly integrated Supports measuring multiple environmental data The DFRobot Environmental Module (CCS811+BME280) builds up a simple environmental monitor station with this multi-function environment sensor! Based on the combination of CCS811+BME280 chip, this module features high accuracy, I2C interface, and fast Measurement. The BME280 can provide temperature and humidity compensation for CCS811 to improve the whole accuracy to a certain extent. It can be used to detect temperature, humidity, barometric pressure, altitude, TVOC, and eCO2. Applications Environment Monitor Air Purifiers Smart Home Ventilation System Weather Forecast NOTE: The chip has stretched the clock in I2C. So, it may be not compatible with some controllers, such as Raspberry Pi.
