Eufy Smart Motion Sensor for Wireless Indoor Security

Broad coverage, long-lasting power:

The Eufy T8910021 smart motion sensor uses PIR (Passive Infrared) technology to detect movement across a 100-degree field and up to 30 feet (9.14 m) away - enough to cover a full room from a single mounting point. One included CR123A battery powers the sensor continuously for up to 2 years, so there is no need to plan around frequent battery changes or cable runs.

Instant alerts, no subscription needed:

Once paired with a eufy Security HomeBase (sold separately), the sensor sends real-time notifications to your phone through the eufy Security app the moment motion is detected - whether you are at home or away. Basic motion detection and app alerts require no monthly fee, making this a straightforward addition to a home security setup.

Flexible mounting and sensitivity control:

The sensor ships with a wall mount, two mounting screws, and a 3M adhesive strip, giving you a choice of installation method with no tools required for the adhesive option. Sensitivity can be adjusted in the eufy Security app so the sensor responds to human movement without being triggered by pets, helping to keep alerts accurate and relevant.

Ecosystem integration and siren capability:

The T8910021 is designed to work within the eufy Security ecosystem alongside products such as the eufy Entry Sensor and other HomeBase-connected devices. When motion is detected, the HomeBase can sound a 100 dB siren in addition to pushing an app notification. Optional 24/7 professional monitoring is available as a separate subscription for those who want an additional layer of cover.

Frequently Asked Questions

Does this motion sensor require a separate hub?

A eufy Security HomeBase is required and sold separately - the sensor cannot send alerts without one. It is compatible with the HomeBase, HomeBase E, and HomeBase 2. Once paired, motion events are relayed through the HomeBase to the eufy Security app on a smartphone, with no wiring needed between the sensor and the hub.

Is there a monthly subscription fee to receive motion alerts on a phone?

No subscription is needed for basic motion detection and real-time app alerts. The moment the sensor detects movement, an instant push notification is sent to a phone via the eufy Security app at no ongoing cost. Optional 24/7 professional monitoring is available as a paid add-on for those who want an extra layer of cover.

Can the sensitivity be adjusted so the sensor ignores pets but still detects people?

Yes - sensitivity can be tuned in the eufy Security app to respond to human movement while filtering out pets, keeping alerts accurate and relevant. The sensor uses PIR technology, which detects body heat and movement, and covers a 100-degree field of view with a detection range of up to 9.14 metres. The T8910021 is designed for indoor use only.

What is included in the box?

The box contains the motion sensor, one CR123A battery, a wall mount, two mounting screws, a 3M adhesive strip, an owner's manual, and a happy card. The adhesive strip means no drilling or tools are required for installation. The included battery provides up to two years of continuous operation, so no cable runs are needed.
