Tata Power EZ HOME MW Motion Sensor is a smart energy-saving switch that controls your connected appliances on detection of motion within 8 m (diameter). It detects any moving object that is cutting through the microwave signal emitted by the microwave sensor, and it immediately switches on the connected appliance or light. When an object or person moves in the room, the sensor detects the motion and activates a signal for different programmed commands, such as opening doors, turning on lights, or sounding an alarm. It also detects daytime and nighttime light automatically. It is easy to install and widely used.
