Task Description
Sensor Integration Integrated environmental sensors (temperature, humidity, eCO₂) on the Thingy:52. Base node ultrasonic sensor was used for proximity/distance measurement (soil moisture sensor was not used).
BLE Comms Setup (Thingy:52 → Base) Used BLE advertising mode from Thingy:52 to periodically broadcast sensor readings. Base node scanned and parsed data without GATT connections.
Data Fusion + Angle Calculation Implemented control logic on the base node to calculate a servo angle from CO₂ and temperature inputs. Also allowed manual override and sensor spoofing via Zephyr CLI.
BLE Comms Setup (Base → Actuating Node) Sent JSON-formatted BLE advertising packets from the base node to the actuator node, which parsed the payload and applied the servo angle.
Vent Control System Actuator node controlled a servo via CRICKIT PWM, updated continuously based on angle received from BLE advertisements.
PC CLI Interface (Ubuntu) Implemented Zephyr Shell CLI interface for enabling/disabling the ultrasonic sensor, switching servo modes, and overriding sensor data in real time.
MQTT Publishing (Windows PC) PC connected to the actuator node over UART. Parsed and published BLE JSON packets to a Mosquitto MQTT broker for visualisation.
Dashboard Integration (Grafana) Viewer PC subscribed to MQTT broker and visualised JSON data using Grafana. Enabled real-time monitoring of environmental state and vent control.
Message Protocol Definition Defined compact custom manufacturer-specific BLE advertising payload format (co2, humidity, temp, angle, distance). Used consistent JSON structure over UART and MQTT.
System Testing and Debugging Conducted staged system integration tests across all nodes. Debugged UART port conflicts, shell/BLE concurrency issues, and Mosquitto networking.
Demo Preparation Developed a full multi-PC demo showing sensor broadcast, base node fusion logic, servo actuation, and MQTT-based visualisation. CLI and fallback modes were also showcased.
