Product description
SEN-HM3301 from Joy-It is a fine dust sensor that measures the concentration of airborne particles using the light scattering method. The sensor can detect particles from 0.3 micrometers and larger, providing real-time measurements for PM2.5, PM5, and PM10 via the I²C interface. This makes it particularly suitable for air quality monitoring in indoor environments, ventilation systems, and environmental monitoring projects.
The sensor supports both 3.3 V and 5 V supply voltages, making it compatible with most microcontroller platforms, including Arduino and Raspberry Pi. Joy-It refers to Seeed Studio’s library Seeed_PM2_5_sensor_HM3301, which offers ready-to-use code examples and easy implementation in the Arduino IDE. During testing, the sensor delivered stable readings after a short warm-up period of about 30 seconds and showed a clear response to changes in particle concentration.
The measurement resolution is 1 µg/m³ with an effective measuring range of 1–500 µg/m³ and a maximum range of up to 1000 µg/m³. The sensor operates within a temperature range of –10 to +60 °C and relative humidity between 10% and 90% (non-condensing).
The SEN-HM3301 is supplied as a complete module with a compact design (41 × 64.5 × 17 mm) and a low weight of 37 grams. It is designed for continuous operation and provides reliable data for professional air monitoring applications. An excellent choice for air quality measurement and analysis in both laboratory and field environments.
