Temperature Sensor Circuit Diagram. Please note that there is no hysteresis in this circuit so that if the temperature changes rapidly then the relay may switch rapidly. The circuit is easy to make and using only few components.
Please note that there is no hysteresis in this circuit so that if the temperature changes rapidly then the relay may switch rapidly. The temperature sensor lm35 is connected to one of the adc channels of microcontroller. In this fire alarm circuit a thermistor works as the heat sensor.
This shows that one can interface six analog values.
Temperature monitor a simple op amp circuit that will trigger a relay when a preset temperature is reached. Temperature sensor circuit circuit diagram the schematic shown here is a project of a simple temperature sensor circuit or we can also say it a heat sensor circuit which will activate an led when receive heat. At normal temperature the resistance of the thermistor th1 is approximately 10 kilo ohms which. This shows that one can interface six analog values.
