Motivation
In order to observe my houseplants' respiration, a prototype of (soap) bubble maker machine is being developed. The quantity of (soap) bubbles will be in accordance to the CO2 level of the plants' (closed) environment.
Materials
- ESP32
- CO2 sensor MH-Z19C
- Stepper motor 28BYJ-48
- Stepper motor driver module ULN2003
- PWM fan AMD Ryzen 7 1700
- 10kΩ resistor
- Power supply 12 volts
- Lots of cables...
