Seeed Studio Studio Grove Dust Sensor PPD42NS - PM2.5 & PM1.0 Dual PWM Output
The Seeed Studio Studio Grove Dust Sensor (PPD42NS) is a digital particulate matter sensor providing dual PWM outputs for PM1.0 and PM2.5 concentrations, designed for easy integration with Arduino, Raspberry Pi, and other 5V microcontrollers via the Grove connector system.
Features
- Dual PWM output for Particle sizes >1μm and >2.5μm (approx).
- Grove-compatible interface for plug-and-play connectivity with Seeed Studio’s ecosystem.
- Operates on 5V DC supply with a standby current of 90mA.
- Measures concentration via Low Pulse Occupancy (LPO) counting method (0-28,000 pcs/L).
- Compact, self-aspirating design with a built-in heater for stable long-term operation.

The PPD42NS dust sensor employs a light scattering principle to detect airborne particulate matter. An internal infrared LED and phototransistor measure the Low Pulse Occupancy (LPO) time of particles passing through the sensing chamber, which is directly proportional to Particle concentration. This digital counting method provides data in particles per liter (pcs/L) or per 0.01 Cubic Sensor feet.
Designed for indoor air quality monitoring, the sensor features a self-aspirating airflow mechanism driven by a built-in heater, eliminating the need for an external fan. Its Grove interface simplifies wiring, offering a negative logic digital output compatible with 5V microcontroller logic levels. The sensor is calibrated for reliable detection of common indoor pollutants like cigarette smoke and household dust.
