When it comes to cutting costs on the electricity bill, there is a good diversity of ways that can help us better control our monthly electricity consumption.

One of the most popular is the outdoor lights with motion sensors, a simple and effective tool that keeps the lights on as long as necessary for more efficient energy consumption.

Good for the environment and money saving

In terms of energy saving, the motion sensor proves beneficial because besides being efficient, it keeps the light on only during the necessary time, increasing the life span of lamps.

How often do we walk around the house leaving the lights on even after we have left one of the


Leaving the lights on in spaces that are not in use can be very expensive, even when the lighting fixtures have low-energy light bulbs.

This becomes a bigger concern in places of passage such as corridors and hallways where we stay a short time, where lights may stay on for a long time.

In addition to the convenience associated with motion sensors, as they can detect your presence and absence by switching the lights on and off, we also highlight security.

They not only activate the lights when you arrive home but also brighten up any unexpected visitors.

Another advantage of the sensor is that it not only automatically turns on the lights, but it also turns them off after a certain time.

This puts an end to the use of any unnecessary running lights.

Motion sensors help to avoid unnecessary consumption when it comes to energy, and therefore contribute to reducing the amount of energy bills.

One of the big plus points is that the purchase price and power consumption of motion sensors significantly offset the investment, as they help avoid unnecessary power usage.

Depending on the device purchased, consumption can range from 0.5W to 8W.

The biggest disadvantage of a motion sensor is that it sometimes fails to pick up the presence of a person in the environment.

Depending on the movement or location, the sensor will take a while to detect that a person has entered the room and turned on the light, or if you need the light for a long time, sometimes the sensor will turn off.

This way, the person needs to move again for the light to turn on. However, the most modern models have been solving this problem associated with this type of technology.


Theoretically, installing a motion sensor is a task with the same level of difficulty as installing a switch.

However, it is important to consider some specific characteristics:

  • You must install them at a minimum height of 2.5metres.
  • You can install the devices on ceilings or walls.
  • It is important to set the angle of the motion detection well for the devices to work properly.
