PIR Motion Sensor Switch

Sensor Switch The Principle: This sensor fitting is an energy-saving and automatic passive infrared sensor switch which adopts infrared detector,IC and SMD technology,it is suitable for installing on lighting fitting for controlling them.The sensor is designed to be maximally sensitive to motion objects that emit heat energy at the wavelength emitted by human body.The infrared sensor switch will be switched on or off automatically when the sensor detect or not the motion heat energy in their“field of view”. Feature: Ambient light level is adjustable: When turn he LUX knob switch toward sun symbol, the sensor light can work at any light level;When turn the knob seitch toward moon symbol,the sensor light can work ONLY under 3 LUX light level. Important: 1.Disconnect the power supply before any work on the sensor switch fixture. 2.Install the sensot switch by a qualified electrician or experienced man. 3.Avoid mounting the sensor switch directly above heat sources such as air conditioner and boiler flues or exposed to direct sunlight. 4.Install the sensor switch at position with vibration free mounting. 5.The most reliable way of detecting motion is obtained when the sensor switch is mounted laterally to the walking direction and no obstacles(such as partition and wall) obstruct the line of sensor vision. 6.Suitable for indoor use ONLY.
