Node Compressor
ESP6822 gebaseerde node die kijkt of the compressor (nog) aan staat. De 'sense' pin zit aan de 'druk' schakelaar van de compressor.
The node is nearly identical to the NodeDeWalt.
Wiring and technical data
The 2 screw terminals are an Optocoupler for AC. It expects AC/230 volt. The RED led on the front is the 'AartLED'.
Code in [[1]]. Opto coupler is wired to GPIO 13, the red LED to GPIO 15 while the green LED sits across the 3v3 of the PSU.
The 3v3 on the duaghter board is wired to the ADC -- so the PSU can power the board through this pin. The VCC pin runs via an 5v->3v3 regulator on the back. This lets us re-program it (e.g. when OTA has failed) with a standard ESP 5v programming board (such as any|Witty Cloud ESP12 or similar board (Around 3 euro for a programmer and an ESP12E).
