Three-in-one Weather Sensor CCS811+SI7021+BMP280 Sensor Module Carbon Dioxide CO2 Temperature and Humidity Height
- CCS811 CJMCU - 8128 + HDC1080 (SI7021) + BMP280
- Carbon monoxide CO VOCs pressure sensor on temperature and humidity of gas
- Triad sensor
- Module size: 18 mm * 21 mm
- Power supply: 3.3 V
CJMCU - 8128 - a gas sensor system on a chip (SSoC) + temperature and humidity sensor, a low-power sensor technology to detect the indoor volatile organic compounds (VOCs).
CJMCU8118 onboard CCS811 structure sketch we can see that this is not a simple sensor, it has integrated the internal MCU, make this kind of sensor has the on-board processing ability, in the case of without the host intervention, can provide equivalent carbon dioxide level or total volatile organic compounds (TVOC) index. At the same time, with the use of separate gas sensor and MCU solution, CCS811 can save equipment cost and as much as 60% of the plate area.
HDC1080 has a temperature sensor of low power consumption, high precision digital humidity sensor
DC1080 is a digital humidity sensor with integrated temperature sensor, it can provide excellent measurement precision with ultra-low power consumption. HDC1080 support wide working voltage range, and compared the competitive solution, the device can be used for all kinds of common provides low cost and low power consumption advantages. Humidity and temperature sensors have been the factory calibration.
- Accuracy of plus or minus 2% relative humidity (typical)
- Temperature accuracy of + / - 0.2 ° C (typical)
- High humidity has excellent stability
- 14 measurement resolution
- Sleep patterns of current of 100 nA
BMP280 is absolute pressure sensor is designed for mobile applications. The sensor module is located in a very compact package. Its small size and low power consumption to allow the battery power supply devices such as mobile phone, GPS module, or a watch.
BMP280 piezoresistive pressure sensor based on Bosch's proven technology has high precision, high linearity and long-term stability and robustness of electromagnetic compatibility. Many equipment operation option provides the highest flexibility, optimization of the device, the power consumption of the performance of the resolution and filter. A test example use cases, the default setting is for developers in order to make the design as simple as possible.
