• The module effectively rejects interference from non-living objects
and also enables detection of non-living moving objects.
• Product support for secondary development, adapted to a variety of
scenarios applications.
• Universal UART communication interface, providing a common
protocol
4 groups of I\O are reserved for user-defined input and output, or
simple interface simulation
• The output power is low, no harm to human body.
• This module is not affected by temperature, light, dust and other
factors, high sensitivity, wide range of applications.
