The LM393 IC can be considered as the equivalent comparator version of the most popular LM358 Op-Amp. While any Op-Amp can be made to work as a voltage comparator, the LM393 proves itself to be advantages by providing an open collector output making it suitable to drive loads. The …
2013-01-11· I am working on designing a circuit using an lm339 and an analog temperature sensor to activate a fan on either high or low speed, I have pretty much all of the details worked out to my satisfaction based on circuits I have found on here and other places on the internet, but when I started putting together my parts list to make an order I noticed that the LM339 is only rated from 0-70*C.
Regarding your requirement, IR ray generated by the transmitter falls on IR sensor L14F, when the signal breaks the voltage at pin6 of IC2a will go positive and IC pin no7 will go low hence the relay will get de-enrgised. you can use normally closed contact of the reay for the purpose. if you want the relay to come on during ray interruption inter change IC2a pin 5 & 6. That will reverse the ...
