Electronic Temperature-Controlled Relay

Today in embedded world it is pretty hard to find an analog DIY project, even though in this project "digitalisation" would be an overkill.

So here is a pretty simple device that works as a thermostat in temperature range of 0-100 degrees Celsius. LM35 is used as temperature sensor whose output voltage changes with temperature from 0V (0 degrees Celsius) to 1000mV (100 degrees Celsius). TL431 precision voltage reference is used to provide with precise reference voltage for comparator, that will be compared with voltage from temperature sensor.

To zavisi samo od releja koji se ugradi u ovaj sklop. Na releju pise (kada kupis relej, procitas struju i napon. To dvoje pomnozis o dobijes maksimalnu snagu).

Pozdrav Zanima me kolika je dozvoljena snaga potrošača koja se smije priključiti na ovaj sklop?

How much is = also add letter "a" at the end of your result! Eg.: 7a
