Motion Sensors

Motion sensors and detectors

Motion sensors, of all the sensors, are the most commonly and widely used class of sensors. It is extensively used in both industrial and commercial applications. These are commonly used because of some of their important features which assist in the conservation of energy in residential, commercial and industrial applications. Apart from that, the installation process of these sensors is extremely simply so that even a simple technician can easily install these sensors.

Motion sensors and motion detectors are also commonly known as movement sensors and movement detectors. Modern houses and offices have these sensors and detectors as an integral part of their automation systems. Home automation system and office automation system is incomplete without these motion sensors and detectors. These sensors can be used in the entire location or selectively in any preferred locations such as: entry gate, corridors, selected rooms etc. The custom location of installation of these sensors can be defined as per the requirement of the customers. Motion sensors are available in latest upgraded automation protocols like: Bacnet, KNX etc in order to integrate the same into the whole building management system. Modern day ultrasonic sensors and infrared sensors are the mainly used technologies for the detection of motion in residential, commercial and industrial applications.

Motion Sensors technology's operating principle

These sensors, as clear from the name, are used to sense motions and movements and are thus called motion detectors. Generally, when we talk about sensing movements then we can imagine we are talking about human movements. But its definition goes beyond human movements to detecting movements of machinery parts or any other mechanical parts and more, which depends on the applications. The basic principle of motion sensors technology is that it constantly monitors any particular area or any linear paths. If movement of any kind is noticed in that area or path, the sensors send out signal to its connected devices so that further action is taken in accordance to those sent signals. Because these sensors are carrying out only switching actions in the installed areas, these are also commonly termed as Motion Sensor Switches. Vacker Nigeria supplies a wide range of models suitable for indoor and outdoor applications as per the requirement of the customers.

Functionality of motion sensors

It is commonly understood that the motion sensors function with the detection of input and thus giving an output to the users. For the detection of input, motion detectors are provided with various technologies. These motion detectors have the provision of transmitter and receiver. Based on the technology used in the motion sensors, the transmitter emits waves of various types and the receiver does the function of receiving the signals back after a certain time interval as programmed. In the duration between the transmission of waves and the reception, various parameters are analyzed by the motion detectors. The motion detectors determine whether or not motion of any kind has been made or not in the designated areas.

All the motion sensors have sensitivity that can be adjusted manually along with customized delay timing on reception at the receptors end. The sensitivity is adjusted as per the required sensitivity in movement detection. For very critical areas, the sensitivity level of sensors can be set high so that slightest of movements can be noticed. Adjustment in delay timing is done to delay the switching once the movement stops. For instance: If you set a delay timing of 30 seconds for the motion sensor then the lights will switch off after 30 seconds since the last movement noticed by the sensors. These lights are also known as Motion Sensor Lights.

Microwave motion sensor

Microwaves are used to operate the security devices in most of the cases. As we are aware, the need and requirement of the security devises have grown more due to surveillance and security concerns.

Microwave motion sensors or detectors are the devises that senses invader’s motion with respect to specific portion and immediately activates the alarm to alert. The microwave motion senor usually works on the principle of “Doppler’s Effect” .

Wireless motion sensor

Do you really think that your house is safe against the burglars? It is likely that the answer of this question is a “NO”. Thus, to ensure safety and security of your house, it is important that you set up the devises that can address such issues for you.

The motion detector or the motion sensor is an electronic device that can pick up any unusual movement within the given range and can alert the security system immediately. This can alert you and the set up system if there is any potential threat pertains against your home. The wireless motion detectors are quite easy to set up as there are no wires that have to be placed against or behind the floorboards or walls.

You can analyse your house and place them same in the areas that needs utmost security. You can conduct such analysis based on the details such as how many rooms are there in the house or how many rooms you need to cover or what are the sizes of the rooms etc.

• Read the features and instructions carefully as that will tell you whether the same is meeting your requirement or not.
• Compare the prices and features with other available products in the market and then choose the ideal product for you.
• Check where you would want to install the sensor to give you best efficiency.
• Check whether the devise is pet-friendly or not.

Apart from the same, also ensure that you and your family members understand the need, requirements and functionality of the devise. This will help you to deal with situations. Such sensors will add a protection layer that will ensure safety and security of your dear ones.

Ultrasound motion sensor

The ultrasound motion sensor has the ability to detect the motion by the usage of sound waves. These detectors can scan the sound and air waves to alert the intrusions. This category has majorly two types of motion sensors.

This type of sensors can emit the sound waves from the quartz crystal transducers. If the sound waves within the given range is disrupted, then the devise immediately reflect back to the security system of the receiver. According to the calibration & sensitivity, the receiver can further signal to the control unit (if at all it is an in ordinary movement) to trigger the security alarm.

2. Passive Sensors: Such sensors function on the sounds such as metal striking sound or breaking the glass sound. Just like the active sensors, these sensors also work on the similar principle and functionality wherein they activate the receiver’s security system by reflecting back to the control unit.

The Ultrasound motion sensors can be used for office security system, car security system, home appliances, to build the intelligent devises etc. such systems are having a life span and durability of 12 to 15 years. It is important to maintain such devises with care as humidity or high temperature can deteriorate the efficiency and life span of the system.

Besides, such devises are expensive hence; you must ensure proper maintenance of the same. It is important to further know that such systems are extremely sensitive and hence can sometimes result in false alarms due to offensive objects for example flying bird or insects etc. If you reside in the area where there is an unusual amount of noise (E.g. Airport or construction area or industrial area or railway station), then this system may not meet your need and requirement.
