There are multiple types of door sensors that depend on the specific use case. These consist of Infrared Sensors, Ultrasonic detectors, Microwave detectors, magnetic switches and photoelectric beams.
Why use Door Sensors?
This is the most obvious use case for a door sensor. Having a door sensor in place can alert you to an unwanted intruder entering a specific room or warehouse. The type of sensor used depends on the size of the door way and the frequency of the event occurring.
Having real time access to the number of people that are entering a specific area can be very useful to retail, shop owners, event organisers, etc.
In the event that the number of people that have entered a certain area has exceeded the security threshold, an alert can be triggered to stop entry. This is especially relevant now, when restriction are applicable to restaurants and shopping centers due to the COVID-19 pandemic
Door Sensors can also be used to monitor the movement of rodents to activate traps and additional workflow measures.
