Adding Enviro+ with Cayenne

Projects Made with Cayenne
4

after spending a few hours ive updated the Python script to read in everything from the Envrio+ Hat board. Attached below. Ive also included a screenshot to show how this is configured.

#this python script works with Pimoroni Envrio+ Air Hat and the additional particle sensor
#shop.pimoroni.com
#this script reads in the BME280 weather sesonor, LTR-559 light and proximity sensor
#MICS6814 Gas sensor which detects 3 types of gases
#PMS5003 particulate matter sensor, reading in PM1, PM2.5 and PM10 particulates
#Triggers can be created within Cayenne dashboard as needed
