Overview
The
evaluation board comes ready-to-use and working out-of-the-box. It provides all the
functionality expected from a wireless motion detector.
Some LEDs show the Bluetooth
®
Low Energy status and motion detection. Then, using the
app,
you can visualize the battery status and signal strength as well as the motion indication.
The Bluetooth
®
Low Energy module is separable to allow the designer to use the analog part only.
The supply and output reading are available on a separate header and all the analog signals are placed on a
testing point.
The
features:
•
®
Low Energy communication
•
•
Analog signal conditioning based on the
•
Window comparator based on the
open-drain comparator
•
•
Powered by a single CR2032 coin cell battery
