Tuya Smart Zigbee Motion Sensor, White, 2-Pack

WIRELESS ZIGBEE MOTION SENSOR – SMART HOME AUTOMATION
The GreenBlue GB740 wireless Zigbee motion sensor is a practical component of a smart home system that allows you to automate daily tasks and enhance the convenience of using smart devices. The sensor detects motion in a room and can trigger pre-programmed scenes, such as turning on lights, activating an alarm, sending a notification to your phone, or controlling other devices connected to the Tuya or Smart Life ecosystem.
Thanks to its compact housing measuring 33x33x28 mm, the device can be discreetly mounted in a location of your choice, such as a hallway, living room, closet, bathroom, garage, or at the entrance to your home. Its small size makes the sensor unobtrusive, while still effectively monitoring the selected area.
MOTION DETECTION AND SMART SCENES
The GB740 Zigbee motion sensor constantly monitors its surroundings and reacts when a person enters its detection range. With a 120° detection angle and a detection range of approximately 5–8 meters, it effectively monitors the most important areas of your home or apartment. Upon detecting motion, the device can automatically send a signal to the app and trigger a pre-set action.
This is the ideal solution for automatic lighting control. The sensor can turn on the lights when someone enters a room and help reduce unnecessary energy consumption when no one is around. After approximately 2.5 minutes without detecting motion, the device enters standby mode, which helps conserve battery life and extends the sensor’s operating time.

LIGHT INTENSITY MEASUREMENT FOR MORE PRECISE AUTOMATION
An additional advantage of the sensor is its ability to measure light intensity. The illuminance value feature allows you to create more advanced and customized automation scenarios. This ensures that the lights turn on only when the room is too dark, rather than every time motion is detected.
This solution works particularly well in hallways, stairwells, bathrooms, children’s rooms, and closets. The sensor can work with smart lighting, outlets, alarms, sirens, switches, or other smart home devices to create a convenient and more energy-efficient home automation system.
CONTROL VIA THE TUYA AND SMART LIFE APPS
The sensor is compatible with the popular Tuya and Smart Life apps, making its setup and daily use convenient and intuitive. In the app, you can check the current battery level, view the event history, and create automation scenes tailored to your needs.
The ability to control the sensor from your smartphone gives you a real-time overview of its operation and allows you to easily connect it to other smart home devices. It’s a simple solution for people who want to enhance the comfort, security, and functionality of their home without a complicated installation.

STABLE ZIGBEE COMMUNICATION
The device uses Zigbee technology, which is often chosen for smart home systems due to its stable communication and low power consumption. For the sensor to function properly, a compatible Zigbee gateway is required to connect the device to the app and other components of the smart home system.
Once paired with the gateway, the sensor can function as part of an extensive home automation ecosystem. It’s a good choice for both simple scenarios, such as automatically turning on lights, and more advanced setups involving multiple devices simultaneously.
SMALL SENSOR, BIG POSSIBILITIES
The GB740 wireless Zigbee motion sensor is a compact, functional, and aesthetically pleasing device that simplifies everyday use of a smart home. It combines motion detection, light level measurement, support for the Tuya and Smart Life apps, and the ability to work with other smart devices. It’s perfect for any setting where convenience, automation, energy savings, and greater control over your home environment matter.
