Smart LoRaWAN Tag for Safe and Transparent Deliveries

The LoRa and WiFi-based patient monitor allows remote, long-range monitoring of patient health data.

We're developing a secure, low-power sensor node using the H2S-Dev board to protect enterprise messaging systems (EMS) from physical and environmental threats. By combining multi-sensor monitoring with encrypted LoRaWAN communication over the Helium network, this system delivers real-time alerts on tampering, intrusion, or environmental anomalies—without relying on Wi-Fi or constant power. It’s ideal for securing remote EMS endpoints, server rooms, or infrastructure cabinets, offering a scalable, cost-effective layer of cybersecurity that integrates seamlessly with existing EMS or SIEM platforms.

This LoRa walkie-talkie works by digitizing and compressing voice, sending it over LoRa in small data packets, and playing it on the receiver.

Introducing the Water Wastage Alarm System — a smart, low-cost solution for Indian households to prevent overhead tank overflows. Using an ultrasonic sensor, this system monitors the water level in real-time, activating an alarm when the tank is full. The system displays the water level on an OLED screen, signals warnings with LED indicators, and can even send SMS alerts via the SIM800L module. Not only does it save water and reduce energy bills, but it’s also affordable, easy to install, and perfect for promoting water conservation in every home. A practical and sustainable solution powered by the H2S-Dev board!

This is a new component I created to help electronics enthusiasts who want to work with PROTEUS and create amazing projects.

A portable, GPS-enabled device to measure river water quality at multiple city locations, storing data for later mapping and analysis, built with low-cost sensors and an ESP32 board.

MicroBlocks is the only LIVE blocks-based programming language for microcontrollers, making it the most intuitive and easy to use tool for getting started in advanced STEM projects! The goal of "STEM 4 All" is to create a LoRaWAN library for MicroBlocks along with a STEM tutorial explaining how to leverage LoRa on this hardware for long-range wireless applications. The tutorial will also cover use of Wi-Fi and BLE for ease of tackling shorter range and higher-bandwidth use cases (Wi-Fi and BLE libraries for ESP32 are already well-supported by MicroBlocks).
