i have a project to build an electronic air fan control cooling circuit. it needs to start to cool when temp increase, give visual indication of overheat condition and must be able to reset it. to do this i have a 10v power supply, AYD 26 temp sensor . any ideas?
design consept? temp sensor - comparator - transistor switch - relay - alarm, fan and reset
Do yuo want a fan that will only turn on when a certain temperature is exceeded?
The simplest way is to use a bi-metal switch which turns on when heated past a certain temperature. A slightly more complicated way is to use a comparator and thermistor to turn the fan on.
