My first embedded project was Wungiel Alert – a device designed for people who heat their homes with coal. A common issue in such cases is forgetting to refill the furnace: the house starts to get cold, and frequently checking the coal level becomes inconvenient.
Wungiel Alert fixes this problem using an ultrasonic distance sensor that monitors the coal level in the furnace. When the fuel starts running low, the device automatically sends a notification via WhatsApp or Messenger (through CallMeBot, depending on the chosen option).
Configuration is handled through a built-in hotspot – once connected, the user accesses a configuration page to select their preferred notification method and enter Wi-Fi credentials. From that point on, the device runs in the background, continuously monitoring the furnace.
The project was eventually discontinued due to a migration to a different platform than Arduino, as well as frequent changes in the CallMeBot API, which would have required constant code adjustments.
