Advantages And Disadvantages Of Infrared Sensors And Ultrasonic Sensors

Advantages and disadvantages of infrared sensors and ultrasonic sensors

infrared sensor 

Excellent: The circuit is simple, and you can do it yourself

Disadvantages: It is greatly affected by light and cannot be measured,

ultrasonic sensor 

Advantages: it can measure distance, is less affected by temperature, and is relatively stable

Disadvantages: The price is relatively expensive, and it is unrealistic to use a large number of ultrasonic modules. Generally, ultrasonic modules sold online can range up to 3 or 4 meters

(If it is used for tracing, it is recommended to use light tube)
