what are sensors ?

• sensor is part of the Arduino uno chip

• sensor is a device that detects and responds to some type of input from the physical environment

• sensors are devices that is used to track progress

• sensors are type of food

IR sensors are now widely used in motion detectors, which are used in building services to switch on lamps or in alarm systems to detect unwelcome guests

• Infrared sensor

• LDR (Light Dependent Resistor) sensor

• Ultrasonic sensor

• touch sensor

are tiny light-sensing devices also known as photoresistors. An LDR is a resistor whose resistance changes as the amount of light falling on it changes. The resistance of the LDR decreases with an increase in light intensity.
