Technical Data

Microcontroller: Arduino Nano
RF Frequency: 433Mhz or 315Mhz 4)
Dust Sensor: PMS7003 or Nova SDS011

1) - The very expensive PurpleAir Air Quality Monitor, uses an Plantower sensor (the PMS5003, older than PMS7003).
2) - See systems compatibility here.
3) - Precision measure of CO2 concentration in open air, is a very complicated task no achievable with simple equipment. According to specifications the error margin of an MH-Z19 sensor is - 50ppm for indoor use, maybe more in outdoor use.
4) - Must match the frequency used by other Transmitter units.
