Build a Hi-low Temperature Sensor Circuit Diagram

This is a Hi-low Temperature Sensor Circuit Diagram. Temperature sensors are devices used to measure the temperature of a medium.There are 2 kinds on temperature Hi and low. Resistors Rl, R2, and the two 2.2 k resistors form a bridge circuit. R2 is a thermistor, and Rl sets the temperature at which L2 lights. Lower or higher temperatures light LI or L3 to indicate an over- or under-temperature condition.
