Different Types of Sensors for Your Building’s Security

We install sensors in all sorts of buildings for security concerns. These detect movement, distance, noise, light, and other signals to trigger the alarm. This way, the security of the building is ensured to keep both living beings and nonliving things inside. While they are so vital, they come in different types depending upon the stimuli they use. These different types of sensors are used in various conditions to achieve the required security.

Sensors and Their Different Types

A sensor is a device that can sense and transmit its set meaning forward. As the function so the name. In the practical sense, a sensor is a device that detects intruders or mishandling and initiates an alarm. In all of this, the sensor detects some anomaly and sends an electrical signal to the alarm. This signal completes the circuit at the alarm and it sounds.

While the mechanism is the same, the sensing ability varies cause of different sensors. They are used as per the ability to detect anomalies in the concerned setting. These can be mechanical in nature or any other. Mechanical estimating services can help with building such alarm systems. Some of these different types as per their sensing ability include:

Motion Detection Sensor

Our movement create ripples in the air. Also, our body has a tendency to block light as an opaque object. All of this can be detected through the sensor. For this, sensors such as infrared or microwave sensors are used. This way, such as someone entering the space of sensors he is detected.

Voice Detection Sensor

A human step creates a substantial noise when taken with normal energy. But this noise can be deduced in pussyfoots. Still talking or dropping something can create noise. These can be detected through sensors having microphones.

Photodetector Sensor

Light too is an important part of any activity. Light is needed to see particularly in case all the building’s lights are out and alarms are turned on. If in that case, some use a flashlight or any other source the sensors trigger the alarm. 

Pressure Sensor

These use pressure transducers and pressure switches to detect anomalies. These sensors are used in industrial processes. In case the liquid, gas, or solid material under process experiences a change in pressure. There can be conditions when someone messes with the processing or some accident happen.

Temperature Sensor

These work in case someone enters a building while alarm systems are working and the building is empty. Their body heat can cause a stir in the air temperature indoors and trigger the alarm. These sensors are thermocouples, thermistors, probes, temperature transducers, RTDs, etc.,

Humidity Sensor

These work almost in the same manner as the temperature sensors. They detect changes in humidity and trigger the alarm. Also, as every human body has its own body heat that can affect the already existing temperature, so does the humidity. The human body affects the standing humidity by utilizing some of it and putting in some share.

Magnetic Sensor

These work with doors and windows. Just as the iron leaves the magnetic field, the sensor rings the alarm. The sensor simply changes the magnetic field into an electrical signal for the alarm. But this only works when the inhabitants leave and turn the alarm system on.


Sensors are an important part of our lives as they help us stay safe. The job is to detect anomalies while the alarm system is active and trigger the alarm. This could mean just creating the sound or sending alert police. Sensors differ in the input they take. It could be motion, voice, light, pressure, temperature, humidity, magnetic field, or various others. To install them MEP estimating services can be used.
