Gravity: Laser PM2.5 Air Quality Sensor For Arduino Category_Radio & Wireless/Antennas • AC/DC 220 V power

• AC/DC 220 V power supply

The SparkFun RedBoard Artemis is a great platform to 'kick the tires' of this amazing module

When used with purifiers or fixed detection equipment

thus it could take 1 or 2 periods(100-200s) to detect the input frequency
