loT-Based Distribution Transformer CONDITION MONITORING SYSTEM
Electronics For You
|November 2024
The proposed IoT-based distribution transformer condition monitoring system enables real-time monitoring of distribution transformers, identifying such deviations as overload conditions and overheating.
Through IoT technology, essential operational data is collected and displayed locally on an LCD interface. Additionally, this data is transmitted remotely to cloud platforms like Adafruit.io for analysis, allowing for proactive maintenance. The system’s architecture incorporates sensors interfaced with a microcontroller, ensuring seamless data acquisition and transmission. This system empowers utilities to optimise power distribution networks and enhance operational reliability cost-effectively.
In the system design, the ACS712 current sensor detects the transformer’s current and identifies overload conditions, while the DHT humidity and temperature sensor monitors the temperature of both the transformer and its surroundings. The ultrasonic sensor tracks the transformer’s oil level. The Adafruit IO dashboard enables data monitoring on an IoT platform. The ESP32 board connects the system to a Wi-Fi network, sending data to the IoT dashboard. The authors’ prototype is shown in Fig. 1, and the required components are listed in the Bill of Materials table.

Smart Air Quality MONITORING SYSTEM
Air pollution is a critical concern in modern living environments, particularly in enclosed spaces such as homes, offices, factories, and laboratories, where prolonged exposure to harmful gases presents serious health risks. Continuous air quality monitoring is therefore essential to maintain safe and healthy indoor conditions. Here we detail the design and implementation of a compact, low-cost, smart air-quality monitoring system based on the Arduino Nano platform.

Musical TEMPERATURE ALARM
Monitoring temperature is essential across many applications, from protecting sensitive electronic equipment to maintaining comfortable room conditions. Conventional temperature alarms typically use buzzers or LEDs, providing only visual, monophonic alerts. Here we present a musical temperature alarm that generates a pleasant melody, rather than a simple beep, when a preset temperature threshold is exceeded.
