There are many different types of sensor that can be utilised through the electronics industry. This includes temperature, level, ultrasonic and IR sensors just to name a few.

Here are definitions of some sensors:
An IR sensor are mainly used for remote control technology – from garage door openers and drones, through to television and PVRs. They use photochips that have a photocell. This photocell emits and detects infrared light.

One of the most common sensors which is used to gauge temperature. They are broken down into sub categories that can include semiconductor, thermistor and thermocouple. They are used to measure a variety of applications including the temperature of a car, as well as in household appliances such as toasters and kettles.

Finally, there is the touch sensor, which as the name suggests is activated by pressure. Touch sensors are also called tactile sensors and are sensitive to touch, force or pressure. They are one of the simplest and useful sensors. The working of a touch sensor is similar to that of a simple switch.There are several different types of touch sensors including resistance, capacitance and piezo. Touch sensors are used in such applications as weighing machines and safety applications.
