Below is a schematic change suggestion for your Smart Plant Pot project:
-
Add a 5V Power Source:
- Component: 5V DC Power Supply
(Note: If you don't already have a generic power source symbol, you may create a custom part named “5V Power Supply” with designator [V1].) - Connections:
- The + output nets to 5V
- The – output nets to GND
- Component: 5V DC Power Supply
-
Connect the MAX6675 Thermocouple Module (U3):
- Power:
- VCC (pin 4): Connect to 5V
- GND (pin 1): Connect to common ground
- SPI Interface Connections:
- SCK (pin 5): Connect to ESP32-DEVKIT-V1 pin D18 (SPI CLOCK)
- ~CS (pin 6): Connect to [ESP32-DEVKIT-V1] pin D5 (Chip Select, e.g., GPIO5)
- SO (pin 7): Connect to [ESP32-DEVKIT-V1] pin D19 (SPI MISO)
- Power:
-
Connect the DHT22 Sensor (U2):
- Power:
- VDD (pin 1): Connect to 5V
- GND (pin 4): Connect to common ground
- Signal:
- DATA (pin 2): Connect to [ESP32-DEVKIT-V1] pin D15 (Digital GPIO)
- Power:
-
Connect the SSD1306 OLED I2C Display (using oled 128x64 ssd1306 i2c with designator M1):
-
Common Ground:
- Ensure all components sharing GND (including the 5V power source, ESP32-DEVKIT-V1, MAX6675, DHT22, and the OLED display) are interconnected to the Ground component.
