Cambridge CMOS Sensors (CCS) has launched the CCS811, the first digital product in its family of ultra-low-power miniature gas sensors.
The CCS811 integrates a metal-oxide gas sensor with a microcontroller sub-system, an ADC and an I2C interface in a single package. Providing an easy-to-use digital measurement of ambient gas concentrations, the CCS811 may be used for indoor air-quality monitoring when embedded in wearables, connected-home devices, HVAC systems and smartphones.
Its highly integrated design makes system implementation easy and helps to reduce bill-of-materials costs. The internal MCU performs the processor operations required to generate measurements of equivalent CO2 levels or to trigger Volatile Organic Compound (VOC) indicators without intervention by the host system’s processor.
The CCS811 can be used to detect ethanol (alcohol) and hazardous gases such as carbon monoxide and a wide range of VOCs. Its unique micro-hotplate sensing technology greatly reduces power consumption when compared to traditional metal-oxide gas sensors, as it provides for very fast cycle and measurement times.
The CCS811 is available in a 2.7mm x 4.0mm LGA package.
- <6μW power consumption in Idle mode
- Rated for >5 year lifetime
- Smart home devices
- Smart office devices
The CCS_EVK04_DEV consists of a CCS811 sensor daughter board with I2C interface and an I2C-to-USB bridge board to enable connection to a computer. Windows®-based software is available for sensor measurements and for logging results.
