Grove - Dust Sensor

The Grove Dust Sensor detects airborne particulate matter (PM) by measuring reflected light intensity within its chamber. Using the Low Pulse Occupancy (LPO) method, it estimates concentration of fine dust particles, enabling students to monitor and evaluate indoor air quality. Ideal for environmental studies, it integrates easily into Arduino or other microcontroller setups via Grove.

Educational Benefits:

• Supports inquiry into environmental science and health.
• Builds data literacy through real-time particulate monitoring.
• Promotes STEM engagement through air quality awareness.
• Demonstrates digital signal reading and PWM output handling.

Classroom Ideas:

• Create a classroom air quality dashboard with visual alerts.
• Compare dust levels in different locations or under various conditions.
• Use in sustainability projects to promote clean air awareness.
• Integrate with displays or buzzers for visual/audio feedback.
