4. ABSTRACT
The world is changing rapidly due to information technology, and all the
people around the world are busy with their jobs, and business, adjusting to
this race. Now, parents are giving more time at their business, office, and jobs,
instead of passing the time at home, but they always get worried and scared
about their children due to abuse of Information Technology and the country's
law and order situation. So, parents are wanted to track and monitor their
child's activities and location from anywhere to resolve their pressure. But it is
not possible for every parent to monitor their child physically due to many
reasons. This system will help parents monitor their child activities from
anywhere using a mobile phone to solve the problem. This android app uses
global positioning system (GPS) and mobile services to find the child location
and secretly stored all the call logs, short message service (SMS) logs, contact
lists, and accurate locations without knowing the children.

to communicate with other devices or the internet.
In summary, PCB boards are a crucial part of IoT devices as they
provide a platform for integrating various components and enable
the device to function as intended.
7. Resistors:
In IoT (Internet of Things) devices, a resistor is a passive electronic
component that is commonly used to limit the flow of electrical
current in a circuit. Resistors are important in IoT devices because
they help to ensure that the voltage and current levels are
controlled and remain within safe operating ranges.
Resistors are typically used in IoT devices for various purposes
such as voltage division, current limiting, and biasing. They can
also be used as pull-up or pull-down resistors in digital circuits,
which helps to ensure that the signal levels are maintained
properly.
There are many different types of resistors available, including
fixed and variable resistors. Fixed resistors have a set resistance
value and cannot be adjusted, while variable resistors can be
adjusted to vary the resistance value. The type of resistor used in
an IoT device will depend on the specific application and
requirements of the circuit.

9. Capacitors:
Capacitors are electronic components commonly used in IoT
(Internet of Things) devices to store and release electrical energy.
They consist of two conductive plates separated by a dielectric
material, which can be made of ceramic, plastic, or other
materials. When a voltage is applied across the plates, the
capacitor stores energy in the electric field created between them.
In IoT devices, capacitors are used for a variety of purposes,
including filtering out noise from power supplies, stabilizing
voltage levels, and providing short-term backup power during
power outages. Capacitors can also be used in conjunction with
other components, such as sensors or microcontrollers, to create
timing circuits, oscillators, and other types of signal conditioning
circuits.
The choice of capacitor used in an IoT device depends on factors
such as the required capacitance value, voltage rating, operating
17. Page | 12
temperature range, and physical size constraints. Some common
types of capacitors used in IoT devices include ceramic capacitors,
tantalum capacitors, and electrolytic capacitors.
10.Boost Converter:
A boost converter is a type of DC-DC converter used in IoT
(Internet of Things) applications to step up or increase the voltage
of a DC power source.
In IoT applications, power efficiency is essential since many devices
rely on batteries or other portable power sources. Boost converters
can efficiently convert a low voltage input to a higher voltage
output, which can power a range of IoT devices, such as sensors,
actuators, and microcontrollers.
The boost converter typically consists of an inductor, a diode, a
capacitor, and a switch, and it works by storing energy in the
inductor during the switch-on time and then releasing it to the
load during the switch-off time. By controlling the switch-on and
switch-off times, the boost converter can maintain a constant
output voltage, even when the input voltage varies.
Boost converters can be found in a wide range of IoT devices, such
as wireless sensor nodes, smart home devices, and wearables.
