What is a Sensor? Different Types of Sensors, Applications

20210402· The other type of IR Sensor is a Reflective Type IR Sensor. In this, the transmitter and the detector are positioned adjacent to each other facing the object. When an object comes in front of the sensor, the infrared light from the IR Transmitter is reflected from the object and is detected by the IR Receiver and thus the sensor detects the object.

IR Sensor : Circuit Diagram, Types Working with Applications

20090914· An infrared temperature sensor used in contacttype instruments include thermocouples, resistance temperature detectors (RTDs), thermistors, and semiconductor temperature sensors. Since contact sensors measure their own temperature they require physical contact with the measured object to bring the sensor body to the object’s temperature.

Infrared Temperature Sensor: what is it and how does it work?

20090914· A typical infrared temperature sensor consists of optical components, IR detector, electronics, and a display or interface output stage. Optics focuses IR energy onto the detector that converts the IR energy into an electrical signal. After amplification, linearization, and temperature stabilization, the electrical signal is converted to a value representing the measured temperature.

What is an Infrared Sensor? (with pictures)

An infrared sensor is an electronic device that emits and/or detects infrared radiation in order to sense some aspect of its surroundings. Infrared sensors can measure the heat of an object, as well as detect motion. Many of these types of sensors only measure infrared radiation, rather than emitting it, and thus are known as passive infrared (PIR) sensors.
