Temperature-Controlled Fan Project: Amplifying Signals for Fan Control

🔥 The objective is to control the temperature of a fan using an operational amplifier and a transistor.

🛠️ Various components, such as resistors and diodes, are used to build the circuit.

🔌 The circuit is connected using a protoboard and wires, and the power supply is properly configured.

🔍 The video discusses the use of a temperature sensor (LM35) and an operational amplifier in a fan control system.

⚡ The LM35 sensor is connected to the 12-volt power supply and its signal is sent to the non-inverting input of the operational amplifier.

🔧 The amplification of the signal is determined by the two resistors (20kΩ and 100kΩ) in the configuration, and the overall gain is calculated using the formula A = 1 + (RF / R1).

🔧 The video shows how to build a temperature-controlled fan using resistors, transistors, and a sensor.

🌡️ By adjusting the resistors, the gain of the amplifier can be set to control the temperature at which the fan turns on.

🌀 The temperature sensor sends a signal to the amplifier, which then activates the fan to regulate the temperature.

🔌 The circuit uses a temperature sensor and operates with 12 volts.

📶 The temperature signal is amplified and sent to the input of the operational amplifier.

⚡ The circuit includes resistors and a motor for controlling the fan speed.
