Investigating potential power current sources capable of handling both AC and DC currents using the LM317 current source.
The sensor outputs a PWM signal, the total pulse widths over 30s proportionally represent the PM2.5 concentration. Or, the "1-10ug/qm particulate concentration" if the datasheet is to be taken ...
