If you mean sensor, a sensor is a device that changes based on some phenomenon and this change is used to measure the change in the phenomenon.For example, assume a device produces a voltage and the amount of that voltage depends on the temperature of the device. It can be used as a sensor for temperature. Assume you put the device in water and another device measures the voltage produced by the sensor. Based on the voltage of the sensor it can display the temperature of the water. So, in this example, the sensor senses the temperature of the water.

A device that measures temperature must have a temperature sensor that responds to changes in temperature, a way to convert the sensor's response into a numerical value, and a display or output to show the numerical temperature value. Additionally, the device should have the ability to calibrate and accurately measure a range of temperatures.
A thermometer is a measuring device used to determine temperature. It typically consists of a temperature sensor, such as a mercury-filled glass tube or a digital sensor, and a scale for measuring temperature values. The design aims to accurately reflect changes in temperature to provide users with a precise reading.
It is an electrical device that tells back the engine temperature to both the temperature gauge and (where fitted) the engine management system.
A thermal coupler is a sensor used to measure temperature in a device. It works by generating a voltage signal that varies depending on the temperature it is exposed to, allowing for temperature monitoring and control in various applications such as heating systems, ovens, and furnaces.
A thermoprobe is a device used to measure temperature, typically in scientific or industrial applications. It usually consists of a temperature sensor at the tip of a probe that is connected to a display or data logger to read and record temperature readings.
A thermocouple consists of two different metals joined at one end, known as the hot junction, and connected to a temperature measuring device at the other end, called the cold junction. When there is a temperature difference between the two junctions, a voltage is generated due to the Seebeck effect. This voltage is then measured by the temperature device and converted into a temperature reading.
A digital thermometer is a device used to measure temperature accurately. It consists of a sensor, typically a thermoresistor or thermocouple, to detect temperature changes, and a digital display to show the measured temperature in numerical form. The sensor detects temperature changes and converts them into electrical signals that are then displayed on the digital screen for easy reading.

A heat sensor is a device that detects changes in temperature and converts them into an electrical signal that can be monitored and analyzed. These sensors are commonly used in various applications, such as monitoring equipment temperature, detecting fires, and controlling heating systems.
