Abstract: The present invention relates to an electromagnetic interference detection device comprises a probe coil for sensing EMI, a three-stage transistor amplifier comprising transistors T1, T2, and T3 for amplifying weak EMI signals, an LM324 comparator for threshold-based detection, a potentiometer for adjusting sensitivity, a relay for activating a buzzer and an LED as alert indicators, an Arduino microcontroller for monitoring and processing the EMI signal, and an I2C LCD display module for real- time visualization of EMI levels. The probe coil senses electromagnetic interference and generates a weak induced voltage, which is amplified through the transistor amplifier stages, stabilized using a diode and resistor network, and filtered using a capacitor. The amplified signal is compared with a threshold voltage set through the potentiometer using the LM324 comparator. When the signal exceeds the threshold, the relay activates the buzzer and LED, while the Arduino processes the signal and displays the EMI level and status on the LCD. The device is powered by a 5V DC supply.
