ppd42ns arduino

Arduino read Dust Particle Sensor - Shinyei PPD42NS

This is a Test for using the NodeMCU with the a dust sensor to track air quality

install:

pio lib install 18 //Adafruit DHT Unified

TODO:

  • test PPD42NS with Arduino
  • test PPD42NS with NodeMCU and level converter
  • send Data to API
  • graph data

Shinyei PPD42NS

from the data sheet: This sensor is to create Digital (Lo Pulse) output to Particulate Matters(PM). Lo Pulse Occupancy time (LPO time) is in proportion to PM concentration. The output from “P1” is for PM whose size is around 1 micro meter or larger.

Model PPD 42NS
Detectable particle size approx. 1 μm (minimum.)
Detectable range of concentration 028,000 pcs/liter (08,000pcs/0.01 CF=283ml)
Supply Voltage DC5V +/-10% (CN1:Pin1=GND, Pin3=+5V) Ripple Voltage within 30mV
Operating Temperature Range 0~45 °C
Operating Humidity Range 95%rh or less (without dew condensation)
Power consumption 90mA
Storage temperature -30~60°C
Time for stabilization 1 minute after power turned on
Dimensions 59(W) × 45(H) × 22(D) [mm]
Weight 24g (approx.)
Output Method Negative Logic, Digital output,Hi : over 4.0V(Rev.2) Lo : under 0.7V (As Input impedance : 200kΩ) OP-Amp output, Pull-up resistor: 10kΩ
