To build a real-time temperature control system using an Arduino board, DHT11 temperature sensor, PWM-controlled cooling fan, and a Peltier module. The system monitors temperature continuously, ...
The Peltier module operates on the Peltier effect: when DC current passes through a junction of two different semiconductors, heat is absorbed on one side (cold side) and released on the opposite side ...
Named after French physicist Jean Charles Athanase Peltier, who discovered the phenomenon in 1834, the module is widely used in applications the need precise temperature control or small-scale cooling ...
