Technical Advancements Inmotion Sensor Light There are different models of motion sensor lights which are light fittings with inbuilt motion sensors. The purpose of these motion sensor lights are to act as a single unit which controls its own switching action using its motion sensors. Such motion sensors can be either IR sensors or ultrasonic sensors. The senor is integrated in the lighting fixture and different models will have sensing capabilities similar to other individual motion sensors. Both ultrasonic sensors and IR sensors are similar in performance but use different technologies for motion sensing.
Lights combined with Motion sensor and Light sensor This is the next technical advancement in which Lights are combined with a motion sensor and a light sensor in a single unit. In this case the light senor can be adjusted to a certain lux level. So if a motion is detected, the lights will be switched ON only if sufficient light is not available. Eg. If during day time, the lights will not be activated if motion is detected. However during night time, the lights will be automatically switched ON when motion is detected. In this category also, IR sensors and ultrasonic sensors can be used, but IR sensors will become more popular and economically feasible.
