so the new temp/humidity sensor is working well on my homebrew weather station (AHT20 replaced with a SHT45)

the SHT45 is a I2C sensor with a built in heater so i can dry the sensor element so it don't drift

it just needs a 0.1s low heat each cycle if the humidity is above 90%, i read the sensor to run a heat/read cycle then wait 3 minutes before i read the data i publish to the cloud dashboard, that allows enough time for the temperature to stabilise to ambient

I'd like to finally start dabbling with little IoT hardware. I know with tariffs it's a tough time to dive in.

Curious where people would start: is it a fool's errand to think I can pick up an ESP32 and hit the floor running? I'm a technically minded individual who understands voltage.

For once I don't have a goal to help drive decisions so sort of just fumbling about.

Wondering if fedi has any DIY indoor air quality/co2/voc/temp/humidity device recomendations?

I found this project, checks all the boxes + cute compact design, but sadly no longer maintained... I'm hesitant to order parts/PCB.
