[yrlmanoharreddy]

Description: Create comprehensive documentation for the Thermistor Sensor component. This will help developers understand its functionality, configuration, and usage within the Pi4Micronaut project.

Developer Notes:

• [ ] Component Description: Document the functionality of the thermistor sensor, which provides real-time temperature readings in Celsius or Fahrenheit.
• [ ] Include details on how it integrates with the Raspberry Pi via an ADC.
• [ ] YAML Configuration:Provide a detailed explanation of the YAML configuration for the thermistor, Including an example YAML file.
• [ ] Schematic Diagram: Include a schematic diagram of the thermistor and ADC wiring for precise replication.
• [ ] Circuit Setup: Add a clear circuit setup image showing the thermistor’s connection to the Raspberry Pi and ADC.
• [ ] Usage Instructions: Write detailed instructions for: Initializing and configuring the thermistor using ThermistorController.java. Reading temperature data. Testing the sensor with Micronaut and Pi4J.

Acceptance Criteria:

• [ ] Component Description - what it can do
• [ ] Add yaml configuration
• [ ] Circuit setup image
• [ ] Schematic diagram
• [ ] Instructions on how to use
