🔬 Live Demonstration — Bench Validation Hardware
This dashboard pulls real-time telemetry directly from the Power Taka bench-scale Co-HTL reactor via
ThingSpeak channel 3388675. An ESP32 microcontroller reads a BME280 sensor every 15 seconds and writes
pressure (field1), temperature (field2), and humidity (field3) to ThingSpeak. The dashboard polls the
Valve state is derived from pressure (OPEN when below 850 hPa), matching the relay logic in the ESP32 firmware. To log valve state separately, send
Data source:
feeds.json endpoint every 15 seconds to display the latest entry and maintain a rolling 20-point history.
Valve state is derived from pressure (OPEN when below 850 hPa), matching the relay logic in the ESP32 firmware. To log valve state separately, send
ThingSpeak.setField(4, valveState) and map field4
in the JS below.
