The Grove - Air Quality Sensor v1.3 is designed for indoor air quality monitoring, capable of detecting carbon monoxide, alcohol, acetone, thinner, formaldehyde, and other slightly toxic gases. Featuring high sensitivity, low power consumption, and long-term stability, it is an excellent solution for household, office, and automatic ventilation applications. Fully compatible with 5V and 3.3V systems, it easily integrates with Arduino, Raspberry Pi, and other popular platforms. Key Features High Sensitivity: Conductivity changes in response to gas concentration for reliable readings. Cost-Effective and Durable: Low power usage and long lifespan ensure lasting performance. Wide Gas Detection Range: Capable of sensing multiple harmful gases including CO, alcohol, acetone, and formaldehyde. Strong Compatibility: Works with 5V or 3.3V systems, supporting Arduino, Raspberry Pi, and more. Beginner-Friendly: Comes with detailed tutorials, sample codes, and community support for quick start. Important Note This sensor is better suited for qualitative measurements rather than precise quantitative analysis. Continuous exposure to heavily polluted air may reduce its sensitivity over time.
