The system is fully customizable from the type of sensors to what modules can be ordered with the units. The base package carries some very good quality and functional sensors for general purpose monitoring in any way the user would like. The following comes in the package –

  • Block with GSM slot and following sensors:
    • Telaire T6703 – CO2
    • BOSCH BME680 – TVOC (Total Volatile Organic Compounds), Temperature. Pressure, and Humidity
    • TI OPT3001 – Light
    • AD DMP401 – Noise

Pricing

The base system starts at $229.00, with optional E-Ink Screen ($49.00), Formaldehyde Sensor or Ozone Sensor ($30.00 each – these sensors are not compatible with each other) and a PM1.0, PM2.5, PM5.0 and PM10 Dust Sensor ($47.00) shipping to the USA starts at $20.00.

That particle sensor looks incredibly similar to PLANTOWER PM2.5 PMS7003. https://www.aliexpress.com/item/32623909733.html?

There seem to exist other clones as well. https://www.aliexpress.com/item/33059840019.html?

That’s because it’s indeed “Plantover PMS7003/G7” as per Tindie listing.

I like the modularity but not the asking price.

For usd 270 you can buy an Airvisual Pro that has a nice LCD and also a battery. That has no VOC but that is the least important so not a big loss.
