Multi-function Environmental Module - CCS811+BME280

Build an easy - to - set - up environmental monitoring station with this amazing multi - function environmental sensor module! It combines the CCS811 and BME280 chips, offering high accuracy, an I2C interface, and rapid measurement. The BME280 provides temperature and humidity compensation for the CCS811, enhancing overall accuracy. This module can detect temperature, humidity, barometric pressure, altitude, TVOC, and eCO2. The CCS811 air quality sensor uses AMS's unique micro - hot plate technology. It has lower power consumption, a shorter preheating time, and a smaller size compared to conventional gas sensors. With an internally integrated ADC and MCU, it collects and processes data and returns it via I2C. The BME280 is a multi - functional environmental sensor that combines a temperature sensor, humidity sensor, and barometer on one board. It has high precision, small size, and offers a ±0.5℃ temperature error and ±2%RH humidity error, with stable performance in the detection temperature range. Note that the chip stretches the clock in I2C, so it may not be compatible with some controllers like the Raspberry Pi. Features include a short preheat time, low power consumption, fast response, high integration, and support for measuring multiple environmental data. Applications are diverse, including environmental monitoring, air purifiers, smart homes, ventilation systems, and weather forecasting. Specifications: Operating Voltage is 3.3V - 5.5V, Working Current is less than 20mA, and the dimension is 20*28mm (0.79*1.10 inches). CCS811 parameters: Preheat Time is less than 15s, I2C Address is 0x5A (default)/0X5B, Operating Temperature Range is - 40℃ - 85℃, Operating Humidity Range is 10%RH - 95%RH, eCO2 Measuring Range is 400ppm - 8000ppm, and TVOC Measuring Range is 0ppb - 1100ppb. BME280 parameters: I2C Address is 0x76 (default)/0X77, Operating Temperature is - 40℃ - 85℃, Temperature Measuring Range is - 40℃ - +85℃ with a resolution of 0.1℃ and a deviation of ±0.5℃, Humidity Measuring Range is 0 - 100%RH with a resolution of 0.1%RH and a deviation of ±2%RH, and Pressure Measuring Range is 300 - 1100hPa. Product documentation is available in the product wiki.

Using this multi - function environmental module is a breeze. First, connect it to a power source within the 3.3V - 5.5V range. Then, use the I2C interface to link it to your controller. Keep in mind that it might not work well with some controllers like the Raspberry Pi due to clock stretching in the I2C. Once connected, the module will start preheating, which takes less than 15 seconds. After that, it's ready to detect various environmental data such as temperature, humidity, and more. When it comes to maintenance, make sure to keep the module in an environment within its specified temperature and humidity ranges (- 40℃ - 85℃ for temperature and 10%RH - 95%RH for humidity). Avoid exposing it to extreme conditions. If you notice any abnormal readings, check the connections first. And always refer to the product wiki for more detailed information and troubleshooting tips.
