Smart Temperature Controlled Fan
₹1,350.00
In StockAn Arduino-based smart fan that automatically adjusts its speed according to temperature changes using an LM35 sensor and a DC motor driver.
Description
This project implements a Smart Temperature-Controlled Fan using Arduino, an LM35
temperature sensor, and a DC motor driver. The fan automatically adjusts its speed based on the surrounding temperature detected by the LM35 sensor. When the temperature rises above a set threshold, the DC motor driver (L298N or L293D) increases the fan speed accordingly. This system is ideal for automatic cooling solutions, improving energy efficiency and convenience in homes, offices, and industrial environments.
Features: Automatic speed control
Energy efficient
Real-time Monitoring
Applications: Smart Home and Offices
Industrial Cooling
Agriculture and Green Houses

- A rain alert system with an LCD display and buzzer, controlled by an 8051 microcontroller, is designed to detect rainfall and provide real-time notifications. The system uses a rain sensor to detect moisture or rainfall, and the microcontroller processes the sensor data. When rain is detected, the 8051 triggers a buzzer to alert the user audibly and displays the rain status on an LCD screen.

This project involves controlling a DC motor’s direction using an 8051 microcontroller, with a buzzer and LED indicating the motor’s rotation state. When the DC motor rotates forward, the microcontroller keeps the buzzer and LED off. However, when the motor is rotated in reverse, the microcontroller triggers both the buzzer and LED to turn on as a visual and audible indication of the motor’s reverse rotation

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.

The Conveyor Belt Object Counter using LDR and 7-Segment Display with the 8051 microcontroller is designed to count objects passing in front of an LDR (Light Dependent Resistor) sensor. The system works by detecting light interruptions when an object crosses the sensor, causing a change in the LDR’s resistance. The microcontroller processes this change and increments an object count. The count is then displayed on a 7-segment display.

A Security Alarm Circuit using the LM358 IC is a simple yet effective system designed to trigger an alarm when unauthorized access or movement is detected. The LM358, a dual operational amplifier (Op-Amp), is used as a comparator to detect voltage changes from sensors like LDRs, IR sensors, or switches, and then activate a buzzer or relay.
