Grove – Laser PM2.5 Dust Sensor – Arduino Compatible – HM3301

The Grove – Laser PM2.5 Sensor (HM3301) is a new generation of laser dust detection sensor, which is used for continuous and real-time detection of dust in the air. Its stable output, low noise, and ultra-low power consumption make it suitable for air conditioners, intelligent air cleaners, and other air quality-related IoT projects.

Features

• Real-time detection: Real-time & continuous detection of dust concentration in the air
• High sensitivity: High sensitivity on dust particles of 0.3 μm or greater
• Stable data reading: Based on laser light scattering technology, readings are accurate, stable, and consistent
• Low-power: Low noise and Ultra-low power consumption
• Grove compatible interface: The product ensures “Plug and Play” and could be versatile for various applications of Grove

Description

The Grove – Laser PM2.5 Sensor (HM3301) is a new generation of laser dust detection sensor, which is used for continuous and real-time detection of dust in the air. Its stable output, low noise, and ultra-low power consumption make it suitable for air conditioners, intelligent air cleaners, and other air quality-related IoT projects.

Different from the traditional pumping dust detection sensor, the HM-3301 innovatively uses fan blades to drive air, and the air flowing through the detection chamber is used as a test sample to perform a real-time and continuous test on the dust of different particle sizes in the air.

This module is a perfect choice for dust detectors, intelligent air purifiers, intelligent air conditioners, intelligent ventilation fans, air quality testing, haze meters, environmental monitoring, and comparable products and applications.
