Over the last decade, advances in the Internet of Things (IoT) have changed the Elevator market enormously. Proactive, condition-based analysis, predictive maintenance is possible in any type of elevator solution by utilizing IoT.


Over the last decade, advances in the Internet of Things (IoT) have changed the Elevator market enormously. Proactive, condition-based analysis, predictive maintenance is possible in any type of elevator solution by utilizing IoT. Smart Elevators can monitor performance, make real-time maintenance decisions, provide updated status, advance reporting, etc. allows us to control and monitor the elevator remotely. 

With an estimation, the smart elevator technology market was valued at USD 18.75 billion in 2019 and is expected to accrue a revenue worth USD 38.27 billion by 2027, with a CAGR of 9.1% during the forecast period.

Why Moving Towards a Smart Elevator Solution is a Good Move?

A smart elevator is controlled or monitored via different forms of connectivity. Elevator internally connects with the custom hardware, using a Wi-Fi or LAN interface, and communicates with the elevator controller using the GPIO pin or UART. Hardware provision itself to IoT central and send the signals (any change in GPIO pin or register value) to the IoT central. Whenever the elevator controller changes the signal it will be detected by the hardware, in that case, the hardware sends that signal to the IoT central. IoT central will export the data to the logic application layer and takedown to the main logic to generate a meaningful signal, fault prediction, fault detection, and sent to the user interface using the WebSocket.

The next-generation IoT Elevator is proving to be more efficient than the traditional elevators. We used to do the maintenance testing, track the records, status, and check the elevators manually. That was too time-consuming and cost-effective. There are multiple benefits of using a smart elevator system, let us understood by discussing the elevator use-cases in brief:

  • Avoid Unauthorized Access: Let’s assume, there are groups of people who are using the elevator to reach their destination. Now, this smart elevator only allows the people to enter who have fingerprint access or smart card which they can use to enter in the elevator. The elevator is connected to a fingerprint sensor or smart card by RS232 DB9 connector, sharing that data using UART. PSOC6 hardware will read the register using the Modbus protocol and transfer the signals to the IoT-enabled public cloud (like AWS, Azure). Therefore, allow only authorized people to use the elevator.
  • Predict Destination: Here, the system will predict using Artificial Intelligence(AI). The system recognizes the face and shares the user information with the IoT-enabled cloud. The IoT cloud will check the user’s authorization and run the Machine Learning (ML) model algorithm and define the destination floor of the user. If the user already visited multiple floors earlier, then there will be a voice message from the elevator’s end using the VoIP protocol, in response to the elevator, the user can speak and tell the arrival floor using the voice command. 

Hence, this kind of smart and innovative technology not only takes us to the upper level in the innovation world but also helps us to fight if any pandemic situation comes again in our life.

Smart Elevator ProcessBenefits of Adopting Smart Elevator Solutions

  • Maintenance Prediction: A fault is an anomaly generated based on the I/O pin or register value of the elevator. Based on GPIO pin and generated fault ML model will predict the level of maintenance and decide at which part of the elevator maintenance is required. When the GPIO pin changes, it will run on the cloud’s logic and generate meaningful data like elevator status and faults
  • Live Elevator Monitoring: Elevators have some changeable information like elevator direction, elevator state, elevator current position, elevator door current status, etc. With a smart elevator, sending a signal to the IoT central and at the same time  IoT central signal to the elevator, a piece of meaningful information will be generated. That information will be updated live on the user interface so that the user can monitor the elevator at their end & remote the location; the user can also track the elevator status and the fault which exists in the elevator
  • Remote Controlling: At some level, if the user needs to pass some commands to the elevator like start-stop the elevator at a specific duration, mainline switch on/off, or run some engine rules on the elevator, based on the user command, the elevator will perform by using the IoT central command. Here, it saves man-power and time to check or do things manually
  • Remote Testing: As earlier mentioned, faults will be identified using the GPIO pin, so based on that list of faults and GPIO value, the elevator technician can debug the elevator issues remotely. With GPIO pin testing value, it will be performed and can be debugged by changing the elevator’s active high value remotely, so the technician can remotely identify the elevator failure causes
  • Cost-Effective: As we know, the cost of the elevator technician will be very high, using the IoT central elevator can be remotely operated and tested so that the technician cost can be leveraged at some level. According to the scenario, the user can set the rules like the usage of the elevator at a specific time or use only some main elevators, etc. leads to power consumption reduction
  • Zero Downtime: Elevator downtime can be negligible if we have such fault detection techniques. The user can also figure out the power failure from the elevator controller with the help of IoT and can specify the rule engine on the power failure that will start the elevator on the backup power. Users can also track the timeout of the backup power as well, so by utilizing that rule elevator downtime can be reduced


VOLANSYS has vast experience in designing and developing a complete IoT solution or modernizing the existing legacy system to a smart one. We have recently worked on one of our elevator projects, where the clients wanted to design a more cost-effective connected elevator solution to manage various sensors including fire, accelerometer, and lift door sensors, without compromising the performance of the solution – Read the complete success story.
