I do have a vThings Air v3 Monitor (http://vair-monitor.com/2017/01/06/vthi ... onitor-v3/) which is based on a
- CO2 Sensor type Figaro CDM 7160
- DUST Sensor type Cubic PM2005
The CO2 Sensor speaks I2C and PWM - a full spec and I2C commands are documented at https://cdn.sos.sk/productdata/52/08/da ... dm7160.pdf
The Dust Sensor speaks I2C as well. Some documentation is here http://diwellshop.cafe24.com/web/DATASH ... PM2005.pdf
My programming skills cover perl and are aged good 20 years. But I am happy to support any tests and beta solutions as needed.
