Hello everyone!
Let us learn about optical sensors and it's applications.

Optical Sensors :

• Optical sensors detect light and convert it into an electrical signal.

• The common types of optical sensors may include photodiodes, phototransistors, and image sensors.

• Optical sensors operate based on the photoelectric effect

• The components of optical sensors are a light source, detector, and signal processing unit.

Applications :-

1. Used in cameras to capture images and videos.
2. Used in industries for manufacturing quality control, process monitoring, and robotics.
3. Used for detecting pollutants, measuring water quality, and keep note on air quality.
4. Used in farming to monitor crop health, soil conditions, and irrigation needs.
