The device works with 3.3 V, to connect with a device working with higher voltage we recommend using a voltage converter.
The PMS7003 Dust/Air Purity Sensor is a high-precision laser-based particulate matter (PM) detector capable of measuring PM1.0, PM2.5, and PM10 concentrations in real time. Using advanced laser light scattering and Mie solution theory, it accurately detects particles as small as 0.3 µm, making it perfect for monitoring smoke, dust, and vehicle exhaust. The module operates on 3.3V UART logic and comes with a MicroUSB adapter, simplifying integration with microcontrollers such as Arduino, Raspberry Pi, and ESP32. With low power consumption, fast response, and a compact form factor, the PMS7003 is an ideal solution for air quality monitoring systems, IoT devices, and smart home environments.
