001 Motion Detected
002 Motion Detected
001 and 002 represent the total count of motion events detected since reset.
ZM_NP_Command
This project demonstrates the use of the ZMOTION Library and API to detect motion with
ambient light detection and a serial command interface. When a motion event is detected,
the status LED is flashed, motion trigger output is pulsed, and a message can be sent via
Serial interface.
Typical current consumption is <1mA @ 3.0V.
The serial command interface includes the following features that help adjust system oper-
ations and performance:
Pet Immunity mode
•
Programmable Digital sensitivity
•
Programmable LED, trigger and motion delay time
•
Ambient light levels and threshold
•
Pass-Through and Hyper-Sense (Micro-Motion) modes
•
Temperature Compensation – adjusts Analog PIR thresholds based on ambient temper-
•
ature
Temperature Change Protection – Ignores motion events generated by temperature
•
changes
Vdd Shift Protection – Ignores motion events generated by shifts in supply voltage
•
Refer to the Serial Command Functions NP file included with the project for a full list of
functions and features.
