Adafruit SCD-41 - True CO2 Temperature and Humidity Sensor STEMMA QT / Qwiic Spedizione:1 Giorno This version has a 4-wire

This version has a 4-wire resistive touchscreen attached It's exactly the same TFT display as PID 1680 but with a resistive touch panel so it is a little more expensive

but one thing it isn't very good at is controlling Servo Motors - these motors need very specific and repetitive timing pulses to set the position

All that air around us, which we bring into our lungs, extracts oxygen from and then breathes out carbon dioxide. CO2 is essential for life on this planet we call Earth we and plants take turns using and emitting CO2 in an elegant symbiosis. But it's important to keep that CO2 balanced you don't want too much around, not good for humans and not good for our planet. The SCD 41 is a
