AGS02MA MEMS TVOC Gas Sensor for air Quality Monitoring in Consumer and Industrial Devices
Key Applications:
- Air purifiers, fresh air systems, and HVAC controls
- Smart home appliances (e.g., air quality monitors, humidifiers)
- Indoor air quality (IAQ) monitoring devices
- Industrial leak detection for light VOCs
- Automotive cabin air quality sensors
- Consumer electronics with air quality feedback
Features:
- Calibrated Digital Output: Factory-calibrated I2C signal for plug-and-play integration, no complex analog circuitry.
- Long-Term Stability: Low drift and >5-year service life in clean air reduce maintenance frequency.
- Fast Response/Recovery: T90 <60 s and recovery <90 s for real-time VOC changes.
- Wide Voltage Compatibility: 3.3–5.5 VDC operation suits 3.3 V/5 V microcontrollers.
- Cost-Effective: Low BOM cost with minimal external components (only pull-up resistors for I2C).
- Compact Form Factor: 12.5×5.8×2.5 mm footprint for space-constrained designs.
