Product description
Temperature Sensitive Switch is a simple project which operates a relay when the temperature around the NTC goes above a set point. The threshold and sensitivity can be adjusted with the onboard potentiometers. This circuit is built using CA3140 Op-amp and NTC temperature Sensor.
