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.
When temperature increases its resistance decreases and vice versa.
At normal temperature the resistance of the thermistor th1 is approximately 10 kilo ohms which.
Compatible with arduino raspberry pi avr pic etc.
The two bc547b transistors are connected as a darlington pair to increase.
The complete schematic to connect the turbidity sensor to arduino is shown below the circuit was designed using easyeda.
Interfacing turbidity sensor with arduino circuit diagram.
30 c to 80 c.
The total current consumption is 10ma.
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.
The calibration of the temperature indicator at 100 c is done by comparing it with a precision termometer.
When lm335 is at this temperature adjust p2 so you read a 1 v difference at the output of the circuit.
