Endpoint: POST /transform Communication Format: JSON Protocol: HTTP/REST

Input JSON Example (From Sampler): { "sensorId": "WS-001", "voltage": 1.25, "timestamp": "2026-03-22T22:42:00Z" }

Output JSON Example (To Pipeline): { "status": "processed", "temperature": 25.0, "unit": "Celsius", "originalVoltage": 1.25 } Design Explanation: Transformer API manages the data processing layer. Uses JSON to validate the incoming sensor data and converts electric signals to values.
