Not good enough…

Over the last year I’ve been testing on and off with the RPI zero and PMS5003 particulate sensor and pimoroni board. Results are just not good enough.

I was able to cram it all into one, weather proof, box:

I was able to install it in the backyard with still connected to indoor wifi (which is tricky with HR++ glazing):

The temperature sensor is still influenced by the CPU heat and thus the relative humidity as well. Want to see now what the options are of connecting the SDS011 directly to a RPI without and clunky USB adapter. To be continued!!
