Cheap PIR sensor
Testing a cheap PIR sensor, seems to be working fine down to 2.0V with no modifications (strange?). 25uA quiescent current at that voltage. Considering it for a battery powered PIR IoT node. Power consumption at 3.0V:
Geiger counter projects indoors outdoors
What is the proper shielding enclosure and measurement location (indoors/outdoors) for Geiger counter projects? Taking mine outside gives Chernobyl level readings , indoors is 0.15uSv/h (15-25 cpm) .. so obviously direct sunlight affects the GM tube heavily, and it must be shielded. Good information here: https://www.gqelectronicsllc.com/forum/topic.asp?TOPIC_ID=4540

Toying with LVGL v7 on my Mac
Toying with LVGL v7 on my Mac in preparation for upgrading my embedded projects to that version. By the looks of it, it will take a few days of fiddling. Why do they make so many breaking changes? Had to go through the same hell when upgrading from v5 to v6; Deja Vu…

Air quality sensor
I just activated a http://luftdaten.info air quality sensor, will be contributing from my home in the suburbs that was missing air quality info. Where I live I measure PM2.5 to be 7.8 µg/m³, but overall air quality in Sofia right now is outrageous.
