Winsen ZH07 Laser Dust Sensor Module
The Winsen ZH07 Laser Dust Sensor Module is an air quality monitoring sensor designed to detect airborne particulate matter such as PM2.5 and fine dust particles. It uses the laser scattering principle where particles passing through a laser beam scatter light that is measured by an internal photodiode to calculate particle concentration.
The module provides real time dust concentration data and supports UART and PWM output interfaces, making it easy to integrate with microcontrollers and embedded systems. It is widely used in air purifiers, ventilation systems, portable air quality monitors and smart home environmental monitoring devices.
