Wireless Occupancy Sensor Code: HC-XPPMS02-KIT Price: $49.99 Quantity: This is a battery operated, motion occupancy sensor which triggers lights and appliances based on motion detection, and/or dusk-to-dawn conditions. If you walk into the room where the Motion Sensor is located, it will send a signal to a Lamp Module to turn a lamp. As long as you keep moving, the light will stay on, and when you stop moving, the light turns off after the amount of time you select. It can also send a signal to an Appliance Module to turn on an appliance such as a fan or any plug-in appliance. It can also send the signal to a Chime Module to set a chime or an alarm. This motion detector mounts easily on the wall. It's small so you can place them almost anywhere. It operates in conjunction with a base transceiver which is included. Additionally, if desired, the sensor can send a signal at dusk to turn on a lamp and a signal to turn it off at dawn, for a dusk-to-dawn operation. Great for energy savings, security and convenience. Great security for protecting an area with more than one entry point.
