Dust Sensor -

1 Dust Sensor The selected dust sensor is PPD42NS, which is made commercially available by Shinyei. The sensor requires +5V and it provides two digital outputs that oscillate between HIGH (voltage higher than 4:0V) and LOW (voltage lower than 0:7V) that are indicative of the number of particles in air. The outputs account
