Wireless Motion Sensor Kit

The Emerson AMCX-US01-SF20R-1PK kit contains one PIR motion sensor and one receiver in white. It detects movement and alerts you with a choice of 36 melodies, four volume levels, four brightness settings and four light colours. The wireless link works up to 280 metres or 918 feet in open space. Power options include AAA batteries or Micro-USB for both units.

Suits entrance monitoring

This kit suits homes, shops and offices that need a simple door-chime, caregiver pager or anti-theft alert without wiring. It is not for buyers who want video verification, smartphone notifications or integration with a wider smart-home platform. The system expands to 32 paired devices, but it does not connect to Wi-Fi, Zigbee or voice assistants.

Simple setup with pairing done

Sensor and receiver arrive pre-paired, so you only mount the bracket with screws or adhesive and choose battery or USB power. The sensor angle adjusts to cover the desired zone. The only common issue is forgetting that batteries are not included, so have AAA cells ready. A power-off memory keeps your settings after an outage.

Questions about this item

What batteries does the receiver need to operate?

The receiver runs on three AA batteries or can be powered via Micro-USB; batteries are not included.

Will the sensor still trigger the chime if I keep my existing wired doorbell?

Yes, the wireless sensor pairs with its receiver independently, so it works alongside any wired doorbell you already have.

How can I confirm the 918‑foot range is working after I mount the sensor?

Walk to the far edge of the coverage area; the receiver will sound the selected melody and flash its light when motion is detected.
