HARDWARE COMPONENTS

Temperature Sensor (DTH11):

The DHT11 sensor is a widely used digital temperature and
humidity sensor. Here are its key specifications:
 Temperature Range: 0 to 50 degrees Celsius
 Humidity Range: 20% to 90%
 Temperature: ±2°C
 Humidity: ±5% RH
 Sampling Rate: 1 Hz (once every second)  Power
Supply: 3.3V to 5V DC
DTH11 Operation: Fig 3.4: DTH11 Sensor

The DHT11 sensor, operating at a consistent sampling rate, continuously monitors the ambient
temperature and humidity, providing a continuous stream of data to the microcontroller. This
iterative process allows the system to adapt fan speed in real-time, creating a responsive and
intelligent mechanism for temperature control in adapting to changing environmental condition.

Relay Module:
A relay module is an electromechanical switch that controls the
flow of electrical power to a connected device, based on
external control signals. Commonly used in electronics
projects, relay modules consist of a coil, a set of contacts
(common, normally open, and normally closed), and a
switching mechanism. The relay module used in the
temperaturecontrolled fan project typically has a single channel
for controlling a single device. In summary, the relay module
acts as the intermediary between the microcontroller and the
fan, enabling the microcontroller to control the fan's power Fig 3.5: Relay Module
supply based on real-time temperature analysis.

This ensures that the sensitive microcontroller is not directly exposed to the high-power circuit
controlling the fan. The relay module, upon activation, either allows or blocks the flow of electrical
power to the connected device. This control mechanism determines whether the device is powered
on, off, or operates at a specific condition. The relay module's operation is dynamically linked to
the microcontroller's decisions, creating a responsive system. Continuous monitoring of data
ensures that the microcontroller can activate or deactivate the relay, adjusting the device power as
needed.
Electrical Fan:
The fan within the temperature-controlled system serves
as a central component, responsible for providing
effective cooling based on the directives of the
microcontroller. This electronically controlled fan is
equipped with adjustable speed settings, allowing for
dynamic adaptation to varying temperature conditions.
Connected to the relay module, the fan's power supply is
under the precise control of the microcontroller, enabling
it to operate at different speeds in response to real-time
temperature analysis.
When the microcontroller determines a need for cooling, Fig 3.6: Electrical Fan
it triggers the relay module to change its switching state, thereby adjusting the fan's operational
speed. The microcontroller, armed with temperature data from sensors such as the DHT11, makes
informed decisions about the required fan speed for optimal temperature regulation. This seamless
integration of temperature sensing and fan control creates a system that can dynamically adjust its
cooling capabilities, providing an efficient and adaptive response to changes in environmental
conditions.

ULTRASONIC SENSOR:
Ultrasonic sensors operate on the principle of emitting
highfrequency sound waves beyond human hearing range and
measuring the time it takes for the echoes to return after hitting
an object. Consisting of a transducer, receiver, and control
circuit, these sensors are widely employed for distance
measurement, object detection, and navigation. They find
applications in robotics, automation, and automotive systems,
offering non-contact distance measurement with high accuracy.
Fig 3.7: HC-SR04 Sensor
Ultrasonic sensors are commonly integrated with
microcontrollers like Arduino and Raspberry Pi for signal
processing and decision-making. With a typical operating range from centimeters to meters, these
cost-effective sensors play a crucial role in enhancing the capabilities of devices and systems
across different industries.

SERVO MOTOR:
A servo motor is a specialized type of electric motor designed for precise
control of angular or linear position, velocity, and acceleration. It operates
based on feedback from an encoder or potentiometer, continuously adjusting
its position to maintain the desired output. Servo motors are widely used in
various applications, such as robotics, CNC machines, automation systems,
and remote-controlled devices.
Their distinguishing feature is their ability to provide accurate and controlled
movements, making them ideal for tasks that demand precision and reliability.
The versatility of servo motors lies in their ability to rotate within a specified
range and hold a position with remarkable accuracy. Fig 3.8: Servo Motor
LDR SENSOR:
A Light Dependent Resistor (LDR), also known as a photo resistor, is a type
of electronic component that exhibits a change in resistance based on the
intensity of light it is exposed to. The resistance of an LDR decreases as the
light level increases, and vice versa. This property makes LDRs widely used
in various applications, such as light-sensitive switches, automatic outdoor
lighting systems, and exposure control mechanisms in cameras.
When incorporated into a circuit, LDRs provide a simple and effective means
of detecting ambient light levels, allowing devices to respond dynamically to
changes in their environment. Their versatility and affordability make LDRs
valuable components in electronics, enabling automation and energy-saving
features in a range of devices and systems. Fig: LDR sensor
Fig 3.9: LDR
GARDEN LIGHTS :
Garden lights, also known as outdoor or landscape lights, serve both functional and aesthetic
purposes in outdoor spaces. These lights are designed to illuminate and enhance the beauty of
gardens, pathways, and other outdoor areas during the evening hours.
With advancements in technology, modern garden lights often feature programmable settings,
allowing users to customize the intensity, color, and timing of the illumination. Garden lights are
directly connected to microcontrollers. Microcontrollers take the the data from ldr sensors and
make the decision of switching on/off the garden lights. ldr sensors send the real time data to micro
controller. Then the micro controllers based on the data and instructions given turns on and off the
garden lights. Thus saving energy and time.
IR(INFRARED) SENSOR:
Infrared (IR) sensors are devices that detect infrared radiation in their surroundings. They operate on
the principle that different objects emit, reflect, and
absorb infrared radiation differently based on their
temperature. IR sensors are widely employed in various
applications, including proximity sensing, object
detection, and temperature measurement.
One common type of IR sensor is the infrared proximity
sensor, which detects the presence or absence of an object
by measuring the reflection of emitted infrared light.
Another notable application is in remote controls, where
IR sensors are used to receive signals and translate them
into commands for electronic devices. In industrial Fig 3.10: IR Sensor
settings, IR sensors play a Fig: IR Sensor crucial role in detecting temperature variations, contributing
to applications such as thermal imaging and process control. Due to their reliability, responsiveness,
and non-contact nature, IR sensors find extensive use in automation, security systems, and consumer
electronics.
