The Tuya Motion Sensor is a great solution to increase the security of your home, provide comfort, and save energy. The sensor detects motion in the detection area by registering heat waves coming from a person, and sends a notification to your smartphone. Create convenient scenarios in conjunction with other devices in your smart home: for example, turning on lights when you enter a room or the air conditioner when it detects motion and exceeds a set temperature.
