A laser particle sensor that is most often used for air quality assessment/control and which can detect particles as small as 0.3 μm (e.g. cigarette smoke) and up to 10 μm. The power supply is 5 V (100 mA), but the logic level of the UART interface is 3.3 V, so it will work without problems with ESP32 or Raspberry Pi.
