Measurement System

This climate monitoring station uses high-precision industrial-grade sensors connected via I²C bus to an ESP32-C6 microcontroller. Data is collected every 30 seconds and transmitted to this server in real-time. The system provides accurate environmental monitoring for Los Angeles Downtown with professional-grade sensor accuracy.

Data Update Frequency: Every 30 seconds
Data Retention: 24 hours of historical data
Sensor Calibration: Factory calibrated, no user calibration required
Operating Conditions: Indoor/outdoor rated sensors

📡 Public API Documentation

This API provides public read-only access to real-time environmental sensor data from Los Angeles Downtown. All endpoints are CORS-enabled and require no authentication. Data is updated every 30 seconds and retained for 24 hours.

GET /api/data.php?action=get

Retrieve sensor data from the last 24 hours

Response Format: JSON

Data Retention: Only last 24 hours of data is kept. Older data is automatically removed.

Response Fields:

temperature (float) - Temperature in Celsius
pressure (float) - Pressure in hPa
humidity (float) - Humidity percentage
latitude (float, optional) - Latitude in decimal degrees
longitude (float, optional) - Longitude in decimal degrees
timestamp (integer) - Unix timestamp (64-bit, UTC)
id (string) - Unique identifier

Example Response:
