Automatic Summer Fan with Temperature Control

Description

Description

This project is all about making an automatic fan control system with automatically switch on and off the fan according to the temperature inside the room. The LM35 is rated to operate over a -55° to +150°C temperature range. Electronic Temperature Control Kit draws only 60 µA from its supply, it has very low self-heating, less than 0.1°C in still air. LM35 Operates from 4 to 30 volts.

This Summer Fan with Temperature Control project uses IC LM35 as a sensor for detecting accurate centigrade temperature. Linearity defines how well over a range of temperatures a sensor’s output consistently changes. Unlike thermistor, the Linearity of precision IC Sensors are very good of 0.5°C accuracies and has a wide temperature range. its output voltage is linearly proportional to the Celsius (Centigrade) temperature.
