Water Temperature Sensor 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.
Water temperature sensor circuit diagram. In this fire alarm circuit a thermistor works as the heat sensor. The two bc547b transistors are connected as a darlington pair to increase. Compatible with arduino raspberry pi avr pic etc. The circuit is easy to make and using only few components.
The total current consumption is 10ma. 30 c to 80 c. The complete schematic to connect the turbidity sensor to arduino is shown below the circuit was designed using easyeda. We have previously built the fire alarm using thermistor and fire alarm system using avr microcontroller today we are building very simple temperature sensor circuit or heat sensor circuit this circuit uses very few and basic components which can be easily available anyone can build it right away.
At normal temperature the resistance of the thermistor th1 is approximately 10 kilo ohms which. Interfacing turbidity sensor with arduino circuit diagram. When temperature increases its resistance decreases and vice versa. The calibration of the temperature indicator at 100 c is done by comparing it with a precision termometer.
