I have a NTC Thermistor rating of about : .75 - 1.1k Ohms @ 25C
This thermistor is used in a motorcycle gas tank.
Typically, a 12v lamp is used to indicate the fuel is low, Thermistor is at it's lest resistance.
I want to replace the 12v lamp with and LED. Seems simple enough since my knowledge of using an LED is using the resistor that comes with the LED in line with a power source.
This doesn't work since the thermistor has constant ground backed by 12v's and even at the highest resistance on the thermistor, the LED stays on.
What is the simplest way for me to get this to work?
I just want the LED to come on when there is no gas in the tank and OFF when there is gas in the tank.
Thank you in advanced.
I'm not sure what other info is needed.
