Hi, I have a question regarding the ADPD18bi. I am not using the board it comes with but instead mounting the sensors onto my own board. I am using an Arduino interphase, I am able to run the code and it does show the trends I need, but unfortunately it does not work at lower concentrations under 1mg/m^3. The way I am able to see the mg/m^3 information is because I am using another sensor to measure the PM concentrations. I would appreciate it if someone familiar with the Arduino interphase or C++ can assist me with this issue. I really want to use the sensor but keep hitting a wall with not being able to reach lower concentrations. If there are any registers that I should specifically use for the lower concentrations please let me know. Thank you so much.
