This Zigbee 3.0 motion sensor helps automate your home. It quickly and reliably detects movement. It has a passive infrared (PIR) sensor with a 110-degree field of view. This SNZB-03P model triggers again in just five seconds. The older SNZB-03 model was slower.
Features and Benefits
- Five-Second Detection Interval - The sensor resets after five seconds. This works well in busy areas where lights need to turn on quickly.
- Long Battery Life - It uses one CR2477 battery. This battery powers the sensor for about three years with normal use. It needs less upkeep.
- Broad Hub Compatibility - It uses the Zigbee 3.0 protocol. This lets it connect to many hubs, including those that work with Home Assistant for local control.
- Smart Scene Integration - Connect it to your Zigbee bridge. It can trigger smart lights, alarms, or routines through your app. It also works with Alexa and Google Home.
Applications
- Automated Lighting: Put it in hallways, bathrooms, or closets. Lights turn on when you enter and off when you leave. This saves energy.
- Home Security Alerts: Use it to watch entryways or rooms. You get a notification from your hub's app if it senses motion when you are away.
- Routine Triggers: Set up a scene. Motion in the morning can turn on your coffee maker and play the news.
Mechanical Ball / Rolling-Element Switches (Simple On/Off)
These are straightforward tilt switches, often using a conductive ball or mercury within a housing. When the device tilts beyond a certain angle, the ball rolls, making or breaking an electrical connection. They provide a simple on/off signal, indicating whether a specific tilt threshold has been crossed. This product functions as a ZigBee Motion Trigger, indicating it provides a digital signal rather than a continuous analogue output. The detection angle for this particular ZigBee Motion Sensor is 100°.
MEMS Accelerometers (Precise Angle Measurement)
MEMS (Micro-Electro-Mechanical Systems) accelerometers are sophisticated sensors that measure acceleration in multiple axes. By sensing the Earth's gravitational pull (1g), they can accurately determine the tilt angle of a device. Unlike simple on/off switches, MEMS accelerometers can provide continuous data on the exact angle of inclination. This Home Tilt Sensor, with its 35 x 39 x 28mm dimensions, is a compact unit that can detect motion over a distance of 6m.
Optical Tilt Sensors
Optical tilt sensors use light beams and detectors to sense changes in orientation. As the sensor tilts, the path of the light beam changes, affecting the amount of light reaching a detector. This change is then translated into a tilt measurement. While not specified for this particular product, optical sensors offer a non-contact method of detection. The Home Tilt Sensor operates within a temperature range of -10°C to 40°C and includes Smart Light Detection features.
Quick Comparison
The Home Tilt Sensor is a ZigBee Motion Sensor and Tilt Sensor, compatible with ZBBridge, eWeLink APP, Alexa, and Google. Simple mechanical ball switches offer basic on/off tilt detection. MEMS accelerometers provide precise, continuous angle data, while optical sensors use light for non-contact measurement. This product, powered by a CR2450 battery, acts as a motion trigger alarm, offering a digital output for tilt and motion events.
The Gravity Sensor
The term "gravity sensor tilt and shake" refers to how a sensor detects changes in its orientation relative to the Earth's gravitational field (1g). A gravity sensor, often an accelerometer, measures the components of this gravitational force along its axes. When the device tilts, these components change, allowing the sensor to determine the tilt angle. For this Home Tilt Sensor, its function as a ZigBee Motion Trigger suggests it reacts to these changes to activate alarms or smart light detection.

Installation Method: Wall-mounted, Ceiling-mounted. Integration: eWeLink APP, Alexa, Google Assistant. Q: What's the detection range and how fast does it trigger an alert? A: This sensor can detect motion up to 6 meters away within a 110-degree arc. It has a very fast response time of less than 500 milliseconds, so your connected lights or alarm will activate almost instantly.. Q: How is this 'P' version different from the older SNZB-03 model? A: The 'P' stands for Performance. This model features an improved battery life that can last up to three years on a single battery. It also includes a smart light detection feature, which prevents it from turning on lights during the day to help save energy.. Q: Does this connect directly to my Wi-Fi router or Alexa? A: No, it doesn't connect directly to Wi-Fi. It uses the Zigbee 3.0 protocol, so it needs a compatible Zigbee hub, like the SONOFF ZBBridge-P. Once it's paired with the hub, you can then integrate it with Alexa or Google Home through the eWeLink app.. Q: Can I use this as a tilt sensor to see if my garage door is open? A: This device is a motion detector, not a tilt sensor, so it isn't designed for that purpose. It senses movement within a space, like a person walking by, rather than changes in orientation or angle.. Q: What comes in the box and how do I install it? A: Inside the box, you'll find the sensor itself, a piece of 3M adhesive for mounting, and the user manual. Installation is simple: just stick the sensor to a clean wall or surface and then pair it with your Zigbee hub using the app..
