I'm looking for a circuit that will represent temperature ranges up to 60
degrees (celcius) using at least 3 LED's or transistors as the outputs for
each range, but I DO NOT want a digital display like a 7-segment or LCD
I want to be able to utilize these outputs to control others parts of my
circuitry (perhaps like voltage calibration).
LED 1 (green) = -10-20 degrees,
LED 2 (yellow) = 20-30 degrees,
LED 3 (red) = 40+ degrees,
I am open to all suggestions.
Thanks in advance.
