Programmed Temperature Controlled Fan



Programmed Temperature Controlled Fan
Circuit depiction
The circuit of programmed temperature controlled fan is work around temperature transducer AD590 took after by operational speaker LM324. AD590 is a temperature transducer, change temperature into relating voltage. The yield of transducer is given to stick 2 of IC2 LM324. The two reference voltage is given to stick 6 and stick 10 through factor resistor VR1 and VR2 individually. The estimation of these variable resistor is altered by temperature (i.e. RL1 invigorated when temperature is above 300C and RL2 stimulated when temperature is underneath 230C).
