Output Sensors

Output sensors are devices or components that receive electrical signals from electronic systems or computers and convert them into physical or perceptible forms of output. These sensors enable the communication of information or commands from electronic systems to the external world. Below are two basic examples of output sensors:

Light Emitting Diode (LED): LEDs are commonly used as output sensors to indicate the status or provide visual feedback. They emit light when an electrical current passes through them. LEDs are often found in electronic devices, appliances, and control panels to indicate power on/off, battery status, connectivity, or various operational states.
Loudspeaker: A loudspeaker is an output sensor that converts electrical signals into sound waves. It is commonly used in audio systems, telecommunication devices, and multimedia devices. When an electrical signal is applied to the loudspeaker, it vibrates a diaphragm or cone, producing sound waves that can be heard by humans.

These examples illustrate how output sensors facilitate the transfer of information or commands from electronic systems to the external world through light or sound. However, it's important to note that there are numerous other types of output sensors used for different purposes, such as motors, actuators, displays, and more, depending on the specific application and desired output. Some additional examples that you likely interact with on a daily basis can be found below.

Light sensor

Sensor sends signal to the processor which activates the output which is light e.g. street lights, LED Displays, children’s night light

Traffic lights control traffic based on a number of inputs including the time of day, the sensors in the road and the pedestrian pushbuttons at a crossing.

LED displays are very common now as they are easily read and are very efficient.

Automatic lights operate when they detect both dark and movement.

Sound Sensor

Sensor sends signal to the processor which activates the output which is sound e.g. speaker, house alarm speaker.

Speakers can be used to produce a wide range of sounds where as buzzers produce very basic sounds. Alarm sirens are designed to be very loud.

Motion Sensors

Sensor sends signal to the processor which activates the output which is movement e.g. Electric motors and servos.

Drones use motors that are controlles by microprocessors that receive inputs from the remote control.

Servo motors produce more precise movement that can be used to control the position of items. You may have seen them used to control the steering on remote control cars.
