Abstract: Patent Title: IoT Based Smart Rodent Repelling System for 
Automobiles 
ABSTRACT 
Our invention "IoT Based Smart Rodent Repelling System for Automobiles" is an 
automatic IoT based electronic rodent repellent system consisting microprocessor / 
microcontroller based embedded control unit contained in water resistant and shock proof 
container for deployment in automobiles for repelling/scaring away the rodents like rats, 
field mouse, moles that can cause harm to the wiring and other vulnerable parts of a 
automobiles. The invented system is contained in box that can easily be deployed under 
the bonnet of automobiles. The invented system has four separate subunits to repel the 
rodents from the automobiles. The invented system has a motion sensor deployed at various 
place of automobiles to detect movement of rodents. Invented system also has pairs of 
infrared / heat / thermal sensor to detect presence of a live, moving creature. The motion 
sensor and infrared red sensor are connected to set of comparators. Comparator 
continuously monitors and compares the signal with a preset threshold value. If incoming 
signal is greater than the threshold value, the comparator sends the signal to the electronic 
control unit for processing. The electronic control unit consist of a 
microprocessor/microcontroller with embedded program to control the operations of 
invented system. The invented system has four subunits to repel rodents. First subunit is 
an audio manipulator with amplifier which produces loud scary sounds to scare away the 
rodents. Intensity and sound generated by audio manipulator keeps on increasing and 
changing audio bass. Second subunit consist of bright light ray generator which produces 
rays of bright light by employing LEDs / lasers / lamps. The intensity of light generated is 
very high so as to create a discomfort on eyes of the rodent. Third subunit is an 
electronically operated spray canister. This spray canister is filled with a rodent repellent 
spray and is operated electronically. Fourth submit is an ultrasonic sound generator it 
produces ultrasonic sound at the intensity which is unbearable for the rodents. The invented 
system has a power converter system which is connected to the battery of automobile and
is used to convert voltage of automobile battery to the levels suitable for the invented 
system. The system consists of microcontroller / microprocessor with an embedded 
program to detect the presence of rodents in automobiles and to activate all four subunits 
to scare away the rodent. The system has electronic control unit which is connected with 
an IoT gateway to transmit the alert signal through 5G technology on the smartphone of 
the owner of automobile. The owner of the automobile can also turn off the system in case 
of false detection or if desired by him, through IoT network.
