a) Two on-board blue LEDs are used for detection feedback.

b) Note that this module is susceptible to natural light and has certain limitations on fields with large variations in ambient light.

c) Support Arduino IDE programming, and provide runtime to simplify programming.

d) Support Robobloq graphical programming for all ages.

e) The on-board gold-immersed M4 mounting holes are easy to install and use the RJ11 interface for convenient connection.
