| dc.description.abstract | The Automated Arduino and peltier Based Smart Cooling system is a smart and
energy-efficient cooling system designed using thermoelectric technology. The
system primarily utilizes Peltier Module to achieve cooling based on the principle of
heat transfer when electric current is applied. Two Peltier modules are used to
enhance cooling performance, where the cold side is placed inside the chamber and
the hot side is cooled externally using heat dissipation methods. To improve cooling
efficiency, two cooling fans are employed for proper air circulation, while a mini
water pump assists in removing heat from the hot side through a liquid cooling
mechanism. The internal temperature and humidity of the chamber are continuously
monitored using a DHT11 Sensor, and the data is processed by an Arduino Uno. A
potentiometer is used to set the desired temperature within a range of 0°C to 50°C,
allowing the user to easily control the system according to requirements. Based on
the comparison between the set temperature and the measured temperature, the
Arduino automatically controls the operation of the Peltier modules, fans, and water
pump through relay modules. When the temperature exceeds the set value, the
system turns ON, and when it falls below the set value, the system turns OFF,
ensuring efficient energy usage. Additionally, a Motor Driver is incorporated to
handle the high current requirements of the Peltier modules (rated at 12V, 6A),
ensuring safe and stable operation. The system is powered by a 220V AC supply,
which is converted into 12V DC using an SMPS, and further regulated to 5V using a
buck converter for low-power components. An I2C LCD display is used to show real
time temperature, humidity, set temperature, and system status, providing a user
friendly interface. Overall, the system offers an efficient, compact, and reliable
solution for maintaining controlled temperature environments in small-scale
applications. | en_US |
