Motion sensor with pet-friendly detection

The Emerson T90M0 is a passive infrared motion sensor designed for indoor security. It connects wirelessly to a compatible eufy HomeBase and distinguishes between humans and pets up to 80 lb to reduce false alarms. The unit includes a CR123A battery rated for five years of operation.

Homeowners who want fewer false alerts

This sensor suits households with pets that trigger conventional detectors. It mounts on a wall or corner at a height of 6 to 7.5 ft and covers a 90° field of view up to 26 ft. Buyers who do not own a supported HomeBase 2, 3, Mini, or Pro cannot use the device.

Requires a compatible HomeBase version

The sensor only functions when paired with a HomeBase 2 on firmware 3.4.1.2 or later, HomeBase 3 on 3.7.2.6 or later, HomeBase Mini on 4.0.5.2 or later, or HomeBase Pro on 4.1.4.3 or later. Without one of these updated hubs the sensor will not operate.

Questions about this item

What wall space and height does the sensor need for its 90° view and 26 ft range?

The sensor measures 1.83 cm wide, 2.3 cm deep and 3.15 cm high and should be mounted at 6 to 7.5 ft height to achieve the 90° field of view and 26 ft detection distance.

How do I pair the sensor with a HomeBase, and what step is often missed?

Update the HomeBase to the required firmware — HomeBase 2 v3.4.1.2 or later, HomeBase 3 v3.7.2.6 or later, HomeBase Mini v4.0.5.2 or later, or HomeBase Pro v4.1.4.3 or later — then add the sensor in the eufy Security app; skipping the firmware update is the common mistake.

When and how do I replace the battery, and what type does it use?

The included 1,400 mAh CR123A lithium battery is rated for up to 5 years; when the app reports low power, open the sensor body and swap in a fresh CR123A cell.
