eufy Security Motion Sensor

I purchased this item but haven't used it, so I'm listing it for sale.

From the manufacturer's website:

Wide Detection Range
With a 100° field of view, it can detect motion up to 9 meters away, making it useful for detecting intruders or preventing wandering. Please note: This product requires connection to a separately sold Eufy Security HomeBase 2 or HomeBase S380 to function.
Easy Installation Without Construction
Simply attach the included double-sided tape to the back of the mounting bracket and install it anywhere you like.
*This product is not waterproof, so please use it indoors only.
Adjustable Detection Sensitivity
You can adjust the sensor's detection sensitivity to suit your environment using the Eufy Security app.
Alert Function
When motion is detected, the HomeBase will sound an alarm of up to 100dB and notify you via the Eufy Security app. You can enable or disable notifications and alarms for home and away modes in the Eufy Security app's security mode settings.
Up to 2 Years Battery Life
The included battery can last up to 2 years. *This may vary depending on the usage environment and methods.

Thank you for looking.
