Capable of tracking up to four moving infrared points simultaneously. Provides real-time coordinates of detected targets to the host computer. Horizontal viewing angle of 33 degrees and vertical viewing angle of 23 degrees. Coordinates are returned in a specific order based on detection sequence. If a target moves out of the field of view, its position is marked as empty (returning 1023, 1023), while other positions remain unchanged. Infrared positioning cameras can be controlled using various controllers with I2C interfaces, such as Arduino and AVR. The camera returns the coordinates of four points at a time. When the infrared positioning camera detects an object, its corresponding coordinates are in the first set of coordinates; other coordinate positions are empty (returning 1023, 1023). If multiple targets are detected, they are arranged sequentially according to the order of detection. The infrared positioning camera can be connected to Processing via serial port using various controllers with I2C interfaces, such as Arduino, to display the real-time coordinates and values of the detected targets. Color: Black Material: ABS Package Contents: 1*Infrared positioning probe Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
