This circuit is a temperature sensing as well as alarm circuit. The circuit raises an alarm whenever the temperature crosses a certain limit. This circuit is a temperature sensing as well as alarm ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

A few simple components are all it takes to create an over-temperature alarm. The circuit in Figure 1 requires only an ordinary negative-temperature-coefficient (NTC) thermistor, two common ICs, and a ...

This temperature monitor alarm circuit continuosly monitors the room temperature and beeps when the temperature drops below 20 degrees centigrade. This capability to constantly monitor the room ...
