  errorText="This field is required"
  validation="error"
  inputSize="lg"
/>

FarmSelect (`farm-select.tsx`)

Features: Custom dropdown with ChevronDown icon
Options Interface: { value: string, label: string, disabled?: boolean }
Styling: Inherits form input styling with appearance-none
Validation: Same validation states as FarmInput

<FarmSelect
  label="Plant Species"
  options={[
    { value: "lettuce", label: "Lettuce (Lactuca sativa)" },
    { value: "spinach", label: "Spinach (Spinacia oleracea)" }
  ]}
  placeholder="Select species..."
  helpText="Choose from available plant species"
/>

FarmCheckbox (`farm-checkbox.tsx`)

Features: Custom styled checkbox with Check icon
Layout: Horizontal layout with label and description
Touch-Friendly: Large variant for mobile interfaces
Validation: Color-coded border states

<FarmCheckbox
  label="Enable Automation"
  description="Automatically adjust environmental parameters"
  inputSize="lg"

  onCheckedChange={(checked) => console.log(checked)}
/>

FarmRangeSlider (`farm-range-slider.tsx`)

Features: Custom range slider with visual track and thumb
Value Display: Optional current value display with units
Mark Points: Optional labeled points along the range
Min/Max Labels: Automatic display of range boundaries
Touch-Friendly: Large variant for mobile

<FarmRangeSlider
  label="pH Level"
  min={5.0}
  max={7.0}
  step={0.1}
  value={6.2}
  unit=""
  markPoints={[
    { value: 5.5, label: "5.5" },
    { value: 6.0, label: "6.0" },
    { value: 6.5, label: "6.5" }
  ]}
  helpText="Optimal pH for nutrient uptake"
/>

3. High-Level Form Templates

PlantConfigForm (`plant-config-form.tsx`)

Purpose: Comprehensive plant configuration with agricultural validation
Sections: Plant Information, Environmental Parameters, Automation Settings
Validation: pH ranges (5.0-8.0), temperature validation, required fields
Agricultural Data: Species options, growth stages, yield tracking

Key Features: - Pre-configured species options (lettuce, spinach, kale, basil, tomato, etc.) - Growth stage tracking (seed → harvest) - Environmental parameter ranges (pH, temperature, humidity, light hours) - Automation toggles (watering, nutrients) - Built-in agricultural validation rules

<PlantConfigForm
  onSubmit={(data) => console.log(data)}
  initialData={{
    name: "Lettuce Rack A1",
    species: "lettuce",
    stage: "vegetative"
  }}
/>

SensorCalibrationForm (`sensor-calibration-form.tsx`)

Purpose: Sensor configuration with type-specific settings
Sensor Types: Temperature, humidity, pH, EC, light, CO₂, pressure, moisture, flow
Auto-Configuration: Thresholds and units update based on sensor type
Validation: Threshold relationships, sampling intervals

Key Features: - Sensor type configurations with appropriate units and ranges - Automatic threshold suggestions based on agricultural best practices - Calibration offset adjustments - Sampling interval configuration (10s - 1h) - Alert and logging toggles

<SensorCalibrationForm
  onSubmit={(data) => console.log(data)}
  initialData={{
    sensorId: "TEMP-001",
    type: "temperature",
    location: "greenhouse-1"
  }}
/>

4. Mobile Optimization
