4 helpful Ways To Stop a Motion Sensor Light From Turning Off

Saving energy in your home, place of business, or school is easy with motion sensor-controlled lighting.

As they frequently shut off if you don’t move around enough, they can also be extremely unpleasant. Can motion sensor lights be made to turn off?

To prevent a motion sensor light from turning off, try these four methods:

Lighting should be quickly turned on and off.

The motion sensor’s sensitivity can be changed.

Get rid of the motion detector.

Ask a trained expert to modify the motion sensors.

The topic of this article is how to prevent lights controlled by motion sensors from turning off. We’ll first provide a brief overview of the operation of motion sensors.

How Motion Sensors Work

In motion sensor lights that are accessible in the marketplace, there are three different types of motion sensors:

Passive Infrared

Radiation in the form of electromagnetic radiation is continuously emitted by everything that exists at a temperature higher than absolute zero (0 K, -273.15 °C, -459.67 °F, 0 °R).

Under normal circumstances, this radiation isn’t visible to the human eye. But it’s detectable by electronic devices. 

Infrared radiation, also known as “heat,” is a type of surplus energy emitted by humans and the majority of the objects we come into contact with.

At wavelengths between 700 nm and 1 mm, infrared light is present (2.75591e-5 in and 0.04 in).

Passive infrared sensors, also known as “passive infrared detectors,” use a camera with a lens that blocks out visible light to continuously measure the temperature of objects in their range of vision.

The camera “sees” everything that emits at a temperature higher than the ambient.

The position of any heat sources over room temperature in relation to the PIR sensor is tracked by a microcontroller that is connected to the sensor.

If these things move more than a certain amount, the microcomputer turns on the light.

Microwave

The following information might frighten some readers of this post, but if you’re in the same room as motion detector lights, there’s a possibility that they’re irradiating you with microwave radiation!

However, as long as you are outside of a microwave oven, microwave radiation (with a wavelength of 1 mm to 1 m or 2.75591e-5 to 0.04 inch) is totally safe for humans.

In their field of vision, microwave motion sensors continuously release a beam of microwaves.

They search for microwave reflections using a unique kind of camera. Through the Doppler Effect, motion can be found.

Similar to PIR sensors, a microcontroller watches for motion in the sensor’s range of vision and activates the light if the amount of motion reaches a certain threshold.

Hybrid

Movable infrared and microwave sensors are combined in hybrid motion detectors.

The most common place they are used is outdoors, when either one’s performance may be hampered by atmospheric conditions.

How To Stop Motion Sensor Lights From Turning Off

equipment as basic as motion detection lights. They can malfunction in a few different ways, but there are also a few ways to alter how they perform.

1. Turn the Light Off and On Again Very Quickly

Turning them off and then rapidly turning them back on is the simplest technique to prevent motion detector lights from going out. The majority of contemporary motion sensor lights have been created or configured to recognise this as an override instruction. The timer is simply reset with the earlier motion sensor lights.

2. Adjust the Motion Sensor Sensitivity

There are detection thresholds in the microcomputers that watch over the motion sensor lights’ sensors. To turn on the light, the microprocessor needs to detect a particular quantity of motion. Furthermore, most motion sensor lights allow for user adjustment of the intensity.

The majority of motion sensor lights that are sold commercially contain sensitivity-adjustable sensors.

The amount of movement needed to switch on the light can be altered as a result.

A person sitting at a desk or a small animal in a yard will both cause the motion sensor to react if the sensitivity is increased.

However, most models either use a dial or a slider for the actual motion sensor sensitivity adjustment process. Motion sensor lights that are more recent and “smart” may frequently be changed via an app.

You should find the steps in the owner’s manual for your specific model.

Trial and error will be needed to get the right level of sensitivity. Once you find a setting you like, you must adjust the sensitivity up and down.

Keep in mind that if you set the sensitivity too high, the light may not turn off until it is turned off.

3. Bypass the Motion Sensor

To completely disable the motion sensor in your motion sensor light would be pushing the boundaries of do-it-yourself. Your lights’ warranty will be void if you do this.

You’re also more likely to damage your lights if you don’t know what you’re doing.

It is common for the motion sensors in motion sensor light fixtures to not be hooked directly into the circuit that powers the lights.

They are instead linked to a relay, which in turn manages the electricity to the lights. An electrical switch that receives its signal from an electrical source is a relay.

Normal operation of the light fixture occurs when it is switched on. A signal from the motion detector turns on the relay and turns off the power to the light.

A switch needs to be placed between the motion sensor and the relay in the sub-circuit of a motion sensor light in order to be turned off. Toggle switches or additional light switches may be used here.

The motion sensor’s signals are blocked while the new switch is in the off position. Your motion sensor light fixture will therefore operate similarly to a standard light source.

Please consult the model’s circuit diagram before attempting to disable the motion sensor in your light fixture. There are online resources for more generic circuit diagrams.

4. Have the Motion Sensors Adjusted by a Qualified Professional

Having them installed or adjusted by a skilled professional is the best option for most people who are dissatisfied with the performance of their motion sensor lights. Most people in this situation would call an electrician or someone who knows about home security.
