Modular Design
The PlantCtrl hardware has been redesigned from a single large PCB into a more flexible, modular system. This allows users to only build or use the components they actually need for their specific setup.
The system now consists of a MainBoard which acts as the controller and several pluggable or connectable modules.
MainBoard (ESP32-C6)
- Processor: ESP32-C6 (RiscV)
- Connectivity: WiFi, Bluetooth, Zigbee/Thread support
- Form Factor: Compact main board with headers for modules
- Fully Open Source: Designed in KiCad
Available Modules
- MPPT Charger: Efficient solar charging for batteries using CN3795.
- Pump Driver: High-current outputs (up to 3A) for pumps and valves.
- Sensor Module: CAN bus-based moisture sensors using CH32V203 microcontroller.
- Battery Management: External BMS board with CH32V203 for battery monitoring.
- Light Controller: For LED nightlights or growth lights using AP63200.
Sensor Module (CAN bus)
The standard sensor module features its own CH32V203 RISC-V microcontroller, which handles the measurement of soil moisture and communicates the results back to the MainBoard via the CAN bus.
- Capacity: Supports up to 16 sensors (typically 8 plants with an A and B sensor each).
- Reliability: Digital communication via CAN bus ensures data integrity even over longer cable runs and in electrically noisy environments.
- Addressing: The A sensor is always used; the B sensor is optional and suggested for larger planters to provide a better average of the soil moisture.
Capabilities
- Moisture Sensors: Supports multiple capacitive or resistive sensors via CAN bus-based Sensor Modules.
- Pumps/Valves: Support for multiple independent watering zones.
- Power:
- Solar powered with MPPT
- Battery powered with optional Battery Management System (BMS)
- Can also be used with a standard power supply (7-24V)
- Efficient Power: Use of high-efficiency DC-DC converters for 3.3V and peripherals.
