Arduino Sensor Connections


Below is a high‐level block diagram showing how the components are interconnected. This diagram summarizes the power supply branching, the voltage regulator, the Arduino, and the sensor/actuator connections. You can review it and let me know any changes you’d like.

Notes:
  • The Power Supply feeds both the Arduino via its VIN pin and the LM7805 Regulator.
  • The LM7805 Regulator provides a stable 5V Rail which powers most sensors, the relay-controlled water pump, the multiplexer, etc.
  • The Arduino provides an additional 3.3V Rail for components like the BMP280, ESP8266, and SIM 800L.
  • Signal connections between the Arduino and peripherals (e.g., TX/RX for communication, digital/analog signals for sensor inputs) are indicated as simplified arrows.
  • Protection and filtering elements (Capacitors, Diodes, MOSFET) are shown to indicate their locations in the design.
  • The Relay Module controls the Water Pump, while the MOSFET is available for additional switching if required.

Notes:
  • The Power Supply feeds both the Arduino (via VIN) and the LM7805 Regulator.
  • The LM7805 creates a steady 5V Rail for powering most sensors, actuators, and modules.
  • The Arduino provides an additional 3.3V Rail for the BMP280, ESP8266, and SIM 800L.
  • Signal connections between devices are represented by arrows. Connections such as digital/analog signals, I2C, and TX/RX lines are simplified for clarity.
  • Supplemental components like capacitors, diodes, and MOSFETs for switching and protection are shown.
