Laser Sensor

Laser optical sensors are considered as optical sensors, but use the laser beam to detect the object or even its exact distance. These sensors are divided into different types such as Through beam laser sensor, Reflective with digital or analog output, which are divided into samples. Through the beam, a transmitter and a receiver are required, and in the Reflection model, a laser beam is reflected to the transmitter with the help of a mirror part, and in other models, the transmitter and receiver are in the same equipment.

Laser sensors can be used in many cases where there is a significant distance between the sensor and the object along with dust or bad environmental conditions. In choosing this type of sensor, the following should be considered.

1. Output type in terms of analog or digital laser sensor
2. Sensor transistor switch type
3. Sensor device power supply
4. Laser sensor sensing distance
5. Sensor operation mechanism and proper sensor application
