Pin No. Name
Description
1
GND
Ground pin
2
Detect Out
Digital detection output.
Signals a valid detection.
Low " no detection
High " valid detection
3
VCC
Power supply pin (3.2 to 5.5V)
4
RX
Serial interface RX input
5
TX
Serial interface TX output
6
Hold Time In
Analogue hold time input. Range from 0 to 3V
0V " minimum hold time
3V " maximum hold time
7
Sensitivity In
Analogue sensitivity input.
Range from 0 to 3V
0 V " minimum sensitivity
3V " maximum sensitivity
8
Misc. Out
Digital miscellaneous output. The function
is programmable over the command set with
the parameter S06.
In the factory setting this output signals the
direction of a valid detection.
Low " backward/receding movement
High " forward/approaching movement
This output is only valid together with a
high on pin 2 (valid detection) except if it
is configured as micro detection output.
