Hello Guys,
So bassically im new to this forum and want help on a curcuit design for a project im doing for my college.
im trying to design a curcuit that detects change in tempreture from a heatsink and depending on the change in tempreture the bar display either goes up or down. now people have been taking about using a resistive temp sensor for the LM3194 but i will be using the LM35 which has increments of 10mV - 1°c. now i was just wondering how to connect this up. the LEDs will have to be full brightness and it has to shine through a smoked plastic sheild, to put it straight it will be part of a PS3 Fan control system. the sensor will be used on a separate design aswell to controll fan speed using PWM but this is a separate curcuit. ive looked on the forums about people making sensors for the cars and i found a diagram but im only wanting to use about 10 LEDs, the design is below.
any help would be greatly appreciated
