Sensor are electronic components that converts signals received from it environment into electrical signals which detected, mesured, quantized and processed into useful information such as turning an LED on/off, driving a motor or activating an actuator.
We live in a world of sensors. We can find different types of Sensors in our homes, offices, cars etc. working to make our lives easier by turning on the lights by detecting our presence, adjusting the room temperature, detect smoke or fire, make us delicious coffee, open garage doors as soon as our car is near the door and many other tasks.
Types of sensor.
There are basically two types of sensors which are;
- Analog sensors
- Digital sensors.
Analog sensors converts signals impulse signals from the environment into analog signals. The signals are then converted into digital signals by an A-DC converter for it to be processed by a microcontroller or micro-processor.
Simply, an analog sensor produces an analog output i.e., a continuous output signal (usually voltage but 0 other quantities like Resistance etc.) with respect to the quantity being measured.
Digital Sensors, in contrast to Analog Sensors, work with discrete or digital data. The data in digital sensors, which is used for conversion and transmission, is digital in nature.
Different Types of Sensors
The following is a list of different types of sensors that are commonly used in various applications. All these sensors are used for measuring one of the physical properties like Temperature, Resistance, Capacitance, Conduction, Heat Transfer etc.
