“Super easy to set up and get running. Only catch was Pypi didn't seem to have the pms5003 library anymore. However, git had it and it was easily copied over. Working in less than an hour (thanks examples) and having fun ... just needed to convert the temp from C to F! ;-) LOL”
Ahoy Mark!
Thanks for the review! If you run into problems installing packages in the future it might be worth checking that you're on the most recent version of Thonny - there was a historical issue that meant that package search wasn't working properly.
“As stated in another review, the temperature climbs immediately upon startup (3°C at least), which makes the measurement innacurate. I feel obligated to punish this. This kind of design flaw is litterally detectable of the first test. I don't how this has not been seen. This make the measurements of the temperature innacurate and thus the humidity measurements (calculated with the T). That's just too bad...”
Ahoy Ange
Thanks for the review! The heat emitted by the RP2040 chip can be adjusted programmatically with an offset - drop us an email at support@pimoroni.com if you need help finding the examples that do this.
“This is a great little board. The only think that would make it better is an example enviro_all_py in imperial measurements for us really slow people in the US.”
“Good:
- The screen is colourful and has good viewing angles.
- Uses little power, ~0.28w w/Pico and display on.
Bad
- Distinctive coil-wine from the device whilst powered, the internal mic picks this up which is a little amusing, but hey it works!
- Temperature climbs ~3'C in about 10 minutes when powered on, and requires significant calibration ~(-)5 deg C offset to read anywhere near what other sensors deem "correct".
- Gas sensor records ohms, which is hard to cross reference to any meaningful metric. In fairness it was never sold as anything other, but only useful for relative VOC concentrations. Given Bosch claim for AI here maybe would be nice to see micropython library offer something other than ohms, or more of a breakdown.”
“The display is really bright and colourful! The sensors all worked with the example code really quickly.
I think the only sensor that needs tuning I think is the light sensor - it's a bit jumpy at a constant light level - I probably just need to average out several readings.
I think this pack is a great item for people or kids who want to play with a microcontroller but don't know what they want to do with it.”
