Three-pack ZigBee PIR sensors for whole-home

This three-pack of NShi PIR motion sensors adds 128° detection across 40 ft in each room without wiring. Each unit runs on two AAA batteries and connects through a ZigBee gateway to the Tuya Smart or Smart Life app for real-time alerts and alarm-history review. Ideal for homeowners who want reliable indoor coverage in hallways, garages, doorways or shops.

Battery-powered design keeps thermals

Passive infrared sensing draws only micro-watts while idle, so the devices stay cool and completely silent during normal operation. The 24-month battery life means no mains wiring, no fan noise and no added heat load in the spaces being monitored. Low-battery warnings arrive in the app before performance drops.

Replaces standalone battery alarms that lack smart

The kit upgrades basic motion detectors that only sound a local siren by adding app notifications, history logs and automation triggers for lights or cameras. The jump is worth it when you need remote awareness and routine creation across multiple zones, but not for buyers who want a hub-free Wi-Fi sensor or compatibility with SmartThings, HomeKit or Zigbee2MQTT.

Questions about this item

How do I mount the sensor and which step causes the most issues?

Use the included film sticker or screws to fix the sensor to a wall or corner; the step people miss is pairing it with a Tuya ZigBee gateway before mounting, because the device will not join the network without that hub.

What ongoing upkeep will the sensor need?

Replace the two AAA batteries when the Tuya Smart or Smart Life app sends a low-battery alert; no other user-serviceable parts are required.

What is the first limitation I will hit during continuous use?

The 128° detection angle and 40-foot range define the coverage boundary; motion outside that cone or distance will not trigger an alert.
