Measuring CO2/Temp/RH/Pressure with ESP8266 version 2
After experimenting a bit, I've made a new iteration of my ESP8266 sensor board, which now sports a PCB design (thanks all fellow Tweakers on GoT!). Some improvements::strip_exif()/f/image/UgT2q7JTIilkM3zhH8XmGAzG.jpg?f=fotoalbum_medium "https://tweakers.net/i/tV61FNC9QJHSHKrqv1p0z_NOLes=/234x176/filters:strip_icc():strip_exif()/f/image/UgT2q7JTIilkM3zhH8XmGAzG.jpg?f=fotoalbum_medium")

Update 20210207: made voltage regulator for BME280 requirement more explicit (thanks @ManS-H!)

- More compact & uncluttered thanks to PCB
- Added one (optionally more distant) temperature sensor to prevent self-heating
- Added deep-sleep cycle to alternatively mitigate self-heating
