Build 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.
CCS811 air quality sensor uses AMS's unique micro-hot plate technology. Compared with conventional gas sensors, it has lower power consumption, shorter preheating time, and smaller size. The internally integrated ADC and MCU allow it to collect and process data, and return via I2C.
BME280 is an environmental sensor that combines temperature sensor, humidity sensor, and barometer in one board. It has high precision, multiple functions, small size, etc. The sensor offers ±0.5℃ temperature error and ±2%RH humidity error. It provides very stable performance within the detection temperature range. Besides, the offset temperature coefficient is ±1.5 Pa/K, equiv. to ±12.6 cm at 1 °C temperature change.
NOTE: The chip has stretched the clock in I2C. So, it may be not compatible with some controllers, such as Raspberry Pi.
