Open-Source LiDAR Time Synchronization System by Mimicking GPS-clock

Acquire and process live and historical air quality data without efforts. Filter by station-id, sensor-id and sensor-type, apply reverse geocoding, store into time-series and RDBMS databases, publish to MQTT, output as JSON, or visualize in Grafana. Data sources: Sensor.Community (luftdaten.info), IRCELINE, and OpenAQ.

Indoor Air Quality Dataset with Activities of Daily Living in Low to Middle-income Communities

A CrateDB Driver for MicroPython.

MATLAB simulator for wireless sensor networks (WSN): models tree and star topologies, checks node-to-parent connectivity, detects the hidden terminal problem between sibling nodes, and estimates per-level and end-to-end packet delivery success probability from a radio link-budget / path-loss model.

Spatio-temporal modeling framework for large-scale migration forecasts based on weather radar networks

Application of the Extended Kalman Filter (EKF) in sensor networks, through its implementation in the problem of object tracking.

ESP32 crash blackbox and field diagnostics Arduino library with RTC/NOINIT logging, ESP-NOW heartbeat monitoring, neighbor watchdog, health scoring, boot storm detection, and metric alerts.

Light weight wireless messaging protocol for low power sensor network, based on slotted aloha access method.

An IoT-based Machine Maintenance Monitoring System for Smart Factories. Utilizes ESP32, vibration, and temperature sensors for real-time condition monitoring and anomaly detection.

MicroPython based MQTT-Sensor on Raspberry Pi Pico W

PPO-based PD-NOMA scheduling for Age of Information minimization in massive IoT networks — POMDP formulation with energy harvesting, SIC decoding, near/far user pairing, and a Drop-and-Add pool management algorithm.

Observation-cost-aware scheduling: the Lambert-W closed-form near-oracle baseline (numpy/scipy, MIT)

Code for running a WildlifeSystems node on a Raspberry PI.

Embedded systems and FPGA projects using Raspberry Pi, sensors, MQTT, SystemVerilog, Vivado, and Basys3 hardware.

A sensor fleet that decides which plant to water — FAO-56 physics, five layers of validation, and a spec the code is audited against.

Remote Control / Positioning System.

ESP32 experiment and node-network workbench — declarative experiments that keep running when you unplug the cable. Sibling to PiStation.
