JOY-IT SEN-HM3301 fine dust sensor module for Arduino & Raspberry Pi

The JOY-IT SEN-HM3301 is a laser-scattering particulate matter sensor that measures PM1.0, PM2.5, and PM10 concentrations in real time. Unlike basic dust sensors that only provide a single output, this module delivers three distinct particle-size readings over I2C, making it suitable for air-quality monitoring projects where granular data matters.

Highlights

• Measures PM1.0, PM2.5, and PM10 simultaneously
• Laser scattering principle for high precision
• I2C interface for easy integration with Arduino, Raspberry Pi, ESP32, and ESP8266
• Wide operating voltage range: 3.3V to 5V DC
• Low power consumption: 20 mA typical operating current
• Measurement range: 0–1000 µg/m³
• Data refresh rate: approximately 1 second

In daily use

The sensor connects via four pins: VCC, GND, SDA, and SCL. Its 3.3V logic level is compatible with most development boards, and the I2C protocol simplifies wiring and code. The module operates in temperatures from -10°C to 60°C, making it suitable for indoor and outdoor enclosures.
