Just trying to switch a relay when a comparator goes high with a transistor but the comparator outputs 1.3v when 'low' which is enough to set the transistor.
Using a 741 opamp as the comparator with a zener diode as one input and a pot providing the source for the other input. Positive rail is approximately 13v while the negative is 0v. Obviously the positive side of the relay is connected to power, just isn't shown in the schematic below.
Is there a good way an easy way to fix this or should I be looking to use another chip with lower output?
