What is an Optical Sensor?19 March 2021
An optical sensor is a sensing device applied to measuring tools. The optical sensor uses the optical principle of the sensor for measurement, and in the process of using the optical sensor, because the measurement is not contacted, and it will not cause damage on the scene during the measurement. Therefore, the measurement of the optical sensor is very accurate, and it is hardly interfered by other factors.
What is RFID?23 March 2021
RFID is the abbreviation of Radio Frequency Identification. The principle of RFID is to carry out non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID has a wide range of applications.
