Mini Project of Electronics Engineering

This consists of the mini project related to Electronic Engg. like Automatic Irrigation Systems, MUSIC REACTIVE LED circuits, and Gas Leakage Detector with implementation steps, advantages and disadvantages. In Automatic Irrigation System. The automatic irrigation control using a microcontroller has been experimentally proven to work satisfactorily. We could successfully set the timer and managed to control the motor over time. This process not only records values of temperature and humidity it also contains the engine accordingly. Analyzing the weather condition motor will automatically maintain the water supply making it possible to maintain greenery without human intervention. In MUSIC REACTIVE LED circuits. When the mic receives loud audio signals then the current at the output collector pin which we connected with the negative of LEDs also goes high and for low audio signals, the output current is also small. So the brightness of the LEDs completely depends on the input sound signals. The Gas Leakage Detector. This is a low-cost, low-power, lightweight, portable, safe, user-friendly, efficient, multi-featured, and simple system device for detecting gas.
