I got the Enviro+ running with a Raspberry Pi Zero but the data is too unreliable to realistically contribute to a Citizen Science project like Luftdaten.info. It’s a great form-factor, but when you click the sensor board directly on the RPI Zero W, both CPU-temperature and RH humidity sensor data a…

Read this thread with interest as I am just starting to set up my Enviro+ and working it in the open, indoors on a desk, the room temp read 20.4C but compensated 6.5C ! Obviously too much compensation. I know I can alter it but better still to move it away from the PI. I was wondering about ribbon …

Cool! I’m a sucker for graphs, is there some tutorial to get that? /Remco

Perhaps nophead can point you in the direction of a tutorial but if you can ‘teach yourself’ he posted this graphical solution in this thread where I got it from: https://forums.pimoroni.com/t/enviro-ohms-to-ppm/12207 As a beginner I can just about read his code but I certainly couldn’t create it,…

Bookmarked, I can work with that, thanks 👍🏻

An update from my end with the Enviro+…I did a couple of physical changes which involved separating the Enviro+ and the Pi. I put the Pi in a neat little case that I originally recorded from Pimoroni but never used. I then used a 40-pin header extension block that effectively lifts the Enviro+ about…

I think I’ve at least partially solved the problem of heat transfer from the RPi to the BME280 as pictured below. I had a BitScope Uno RPi Blade and an RPI-4 from another project. Mounted the Pi and the Enviro+ hat separately on the blade with a small exhaust fan pulling outside air through a scre…

I tried a ribbon cable and very literally smoked the hat. Obviously, the ribbon cable challenged my ability to visualize the header orientation. Think 3.3V got traded for 5V or GND!

Yes, I triple checked it and took a reference pic with my phone haha Your setup is indeed beefier. A RPI4 is way more computing power that you need for this, possibly you can use that for some local visualization with Grafana or something en clip a webcam to it to stream to YouTube? Same goes for …

I successfully corrected the temperature and humidity errors by doing two things. Firstly, I separated the Raspberry Pi Zero and the Pimoroni Enviro+ boards, placed the PMS 5003 between the two boards and used ribbon cable to interconnect them. I’ve designed and built a 3D printed case to hold them.…

Here’s another photo of the case, this time showing the underside ventilation. [20200214-IMG_1812]
