I am currently studying a coursewok set on sensors. If anyone knows the method and circuit for an NTC thermistor experiment or any information on the thermistors at all it would be greatly appriciated.
An NTC thermistor is a type of temperature sensor made from a material called a negative temperature coefficient (NTC) material. This material has the property of decreasing its electrical resistance as temperature increases.
An NTC thermistor works by measuring changes in electrical resistance as temperature changes. As the temperature increases, the NTC material's resistance decreases, allowing more current to flow through the circuit. This change in resistance can be used to calculate the temperature of the thermistor.
The purpose of this experiment is to demonstrate the use of an NTC thermistor as a temperature sensor and to observe the relationship between temperature and electrical resistance in the thermistor. This experiment can also be used to calculate the temperature coefficient of the NTC material.
To conduct this experiment, you will need an NTC thermistor, a power supply, a voltmeter, a resistor, a multimeter, and wires for connecting the circuit. You may also need a heat source, such as a hot plate or a hairdryer, to change the temperature of the thermistor.
NTC thermistors have a wide range of applications, including temperature sensing and control in electronic devices, automotive systems, and household appliances. They can also be used for temperature compensation in circuits and as part of self-regulating heating systems.
