Over Temperature Monitors Circuits

  • MICRO POWER OVER-TEMPERATURE ALARM
    The circuit is powered for years by a single 3 volt lithium battery. It sounds an alarm when the temperature exceeds a certain point. With some minor changes the circuit could also be configured for an under temperature (freeze) alarm. The circuit uses a cheap but accurate thermistor as the temperature sensor.
