The working principle of infrared sensors is based on the detection of heat, so any temperature fluctuations may affect the response of the sensor. Sometimes, even if there is no object in the sensing range of the sensor, the sensor may misjudge and trigger the lamp to turn on.

LED night light bulbs have a higher energy utilization rate, usually converting 80%~90% of electrical energy into light energy, and only 10%~20% of the energy is dissipated in the form of heat energy.

The sensor sensitivity is too high Most LED night light lamps are equipped with sensitive motion sensors to respond quickly to motion in low-light environments. However, if the sensor sensitivity is set too high, it may react to minor environmental changes or non-human movements.

Many modern LED night light lamps have a "constant light mode" option. In this mode, the lamp does not rely on the trigger of the motion sensor, but is kept on all the time directly through the switch or remote control.

The power of led nite light bulbs is usually low, generally between 0.5W and 5W. In contrast, traditional incandescent bulbs are generally between 25W and 100W, and fluorescent lamps are generally between 10W and 20W. Therefore, the power of LED night lights is very low.

Placing LED night lights with sensors around the bed can significantly improve the convenience and safety of night life. For people who often get up at night or have difficulty in moving, LED night lights with sensors provide touch-free automatic lighting, without the need to fumble for switches, and conveniently return to bed or perform other activities quickly.

Unlike traditional night lights that need to be turned on and off manually, LED motion sensor night lights monitor the surrounding environmental conditions (such as light, movement, sound, etc.) through built-in sensors, and decide when to turn the light on and off based on these changes.
