## Description

Seeeduino V4.2 is an Arduino-compatible board, which is based on ATmega328P MCU, Arduino UNO bootloader, and with an ATMEGA16U2 as a UART-to-USB converter. The three on-board Grove interface can make your board connect to over 300 Grove modules.

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. With its stable output, low noise, and ultra-low power consumption, it is suitable for air conditioners, intelligent air purifiers, 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 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 relative products and applications.
