Selected Work
Design of an IoT-Based Long-Term Monitoring System Using LoRa for Temperature and Dissolved Oxygen in Lake Toba
A comprehensive, real-time Internet of Things (IoT) system engineered to monitor critical water quality parameters, specifically Dissolved Oxygen (DO) and Surface Temperature, at Lake Toba. The system architecture leverages LoRa wireless technology for long-range, low-power data telemetry from field sensor nodes to a central gateway.
The data pipeline is processed by a flow-based engine and stored in a time-series database hosted on a self-managed, secure Linux cloud server. To ensure accessibility and data-driven decision-making, the telemetry data is visualized through a responsive, high-performance single-page application (SPA). The dashboard features interactive historical charts, automated data aggregation based on time intervals, and real-time network health monitoring (RSSI & SNR). The entire infrastructure is secured with SSL/TLS encryption and integrated with a custom CI/CD pipeline for seamless, zero-downtime automated deployments.
Bird Pest Detection and Repelling System
Automatic Bird Pest Detection and Repelling System is an IoT-based agricultural system designed to automatically detect bird activity in rice fields and respond without continuous human supervision. The system uses multiple PIR sensors connected to an ESP32 sensor node to detect movement, then transmits detection events to the main node via LoRa for long-range communication. Once a bird is detected, the main node generates a high-frequency sound signal using PWM to drive piezo buzzers through an audio amplifier, while simultaneously sending a real-time notification to farmers through Telegram. The system is also designed with a solar-powered energy system, making it suitable for remote agricultural environments with limited access to conventional electricity.
Smart Garden
Designed and developed an end-to-end Internet of Things (IoT) solution to monitor soil conditions and automate watering processes. The system operates on an ESP32 edge device integrated with multiple capacitive soil moisture sensors. It features a custom fault-tolerant logic (Smart Average) that filters out hardware anomalies, preventing overwatering if a sensor disconnects. The edge device utilizes a hysteresis control algorithm for efficient water pump activation.
Telemetry data is transmitted seamlessly via MQTT protocol to a Node-RED data pipeline, which processes and logs the information into an InfluxDB time-series database for robust historical data retention.
