Volatile organic compounds (VOCs), explosive or toxic gasses, humidity, and scents are just a few examples of the dangerous gasses that can be detected by gas sensors.
A digital gas sensor is a tool that can react to the presence of gas that meets particular criteria. The concentration of gas in the atmosphere alters a material or circuitry attribute of the sensor, which is how gas is detected.
The global digital gas sensors market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Digital Gas Sensor, CCS811 is released by Cambridge CMOS Sensors. The first digital product in the CCS800 product family of ultra-low power micro gas sensors, the CCS811 was launched today by Cambridge CMOS Sensors (CCS), a semiconductor business with market-leading gas sensor solutions to monitor the local environment.
For smartphones, wearables, and connected home devices, the CCS811 integrates a metal oxide gas sensor with a microcontroller subsystem to offer Indoor Air Quality Monitoring, ease of design, increased battery life, and decreased system cost.
Based on CCSs specialized Micro-hotplate technology, it offers a very dependable gas sensor solution, incredibly quick cycle times, and a considerable average power consumption decrease when compared to conventional metal oxide gas sensors.
The CCS811 features a metal oxide (MOX) gas sensor, a microcontroller, an analog-to-digital converter (ADC), and an I2C digital interface.
All of these components are housed in a small, low-cost PCB-compatible 2.7 x 4.0 mm, 0.6mm LGA package. Identifying Hazardous Gasses and Ethanol. Based on its Micro-hotplate technology, the CCS811 may be used to detect ethanol (alcohol), dangerous gasses like carbon monoxide (CO), and a variety of volatile organic compounds (VOCs).
The CCS811 offers a number of measurement modes that have been low-power optimized, averaging 1.2mW per minute for active sensor measurement and 6uW in idle mode.
In order to depict equivalent CO2 (eCO2) level or TVOC measurement in real-world contexts, where humans are the primary source of VOCs, CCS811 includes an integrated MCU that regulates the sensor drive modes, ADC measurements, and processes raw sensor data during gas detection. This on-boarding processing lessens the host system’s overall processing and power requirements.
