Como hacer un controlador de ventilador por temperatura ( 45ºC )

In this video I will show you how to set up a circuit that controls a fan to cool some projects without the need to program and that comes at a price of less than 2 euros. It is important to use mosfet if we want the fan to turn on from 0 to 100% when it detects the high temperature. If we want the fan speed to be linear in terms of temperature then we will use a transistor. NTC resistance values ​​for activation temperature (IN MOSFET). 3.3k 0ºC - 4ºC 3.5K 10ºC - 13ºC 3.8K 20ºC - 24ºC 4.3K 30ºC - 33ºC 4.7K 40ºC-45ºC 5K 50ºC - 53ºC 6.8K 78ºC - 82ºC 8.2K ​​ 110ºC - 114ºC 10K 155ºC - 160ºC The values ​​shown here are experimental. Values ​​may vary slightly depending on the mosfet used. If you liked the video, give like share and comment. If you want to see more content related to the subject of electronics subscribe.
