“Seems to work, and easy to use thanks to provided python modules. I'm not convinced about the sensor readings, though. Suspiciously low. Often 0 or single digit readings. Spiking quite high when cleaning a carpet in front of it, so something's working.”
“Really like this. Very easy to set-up with the python examples and had the code outputting to a MQTT broker easily (getting it to work with a public one, HiveMQ, was a bit more tricky, but that's not the fault of the unit but once going it sits there doing its thing). Virtually silent (it's nice to be able to hear the tiny fan if it's put up to the ear. Works nicely with Enviro+ I had for the Pico.”
“I have been using a PMS5003 as part of a prototype weather station for almost a year, it's been in a wooden box sitting on a pole in the backyard operating 24/7 and has worked well providing a long time series of data. It detects BBQs and log burners and correlates well with a local authority air quality measuing station which cost a lot more then the PMS5003. I'm certain there is a lot more that can be extracted from the data, such as volcanic activity(?). It does need a 5V supply to work properly, but that's not a big issue.”
“PMS5003 arrived on time, was well packed and in good condition. It has been used in an Arduino project and appears to be working as intended. The service and delivery from Pimoroni was excellent.”
