An important part of retrofitting is gaining the ability to use the data gathered by the sensors, and in the case of controlling devices remotely, gaining the ability to receive the signal necessary to control the device. These days, communication boils down to either wired or wireless communication.
Wired communication is where the device is directly connected via cable to either an existing network, gateway, or other relay. Wireless communication is where devices that are close enough to an existing network use Wi-Fi connectivity, which provides reliable and fast communication allowing for real-time monitoring and control of devices.
Where Wi-Fi is impractical, cellular communication also offers the type of speed that can support real-time monitoring and control, but often at a very high cost. For situations where neither option is feasible, low-power wide-area networks LPWAN offer large coverage areas, low costs, and limited battery requirements but at the cost of slower and lower bandwidth connectivity.
This solution generally means not having the ability to use either real-time monitoring or control and it may also limit the amount of data that can be communicated.
Some equipment was never designed to communicate at all. Be it irrigation pumps along a stream, lights, or sprinklers, it was not all that long ago that there was simply nothing for such equipment to feasibly communicate, and no one available to read the communication. These types of equipment require additional hardware so that IoT and other communications can be used. In some cases, it may be possible to connect new sensors that monitor existing mechanical processes or the voltage of electrical currents.
Such modifications would also make it necessary to be able to communicate such readings. Thus, this type of hardware modification would also include a communication method such as an ethernet port or even a wireless communication system. Likewise, equipment such as a sprinkler or pump that turns on and off does so because of some physical or electrical condition.
A pump might turn on whenever water is present. Other equipment may use a preset timer. Processes like these could be reconfigured with modified equipment that would allow an operator at a remote console to turn something such as a pump or light on or off, or set something faster or slower, or whatever is necessary, all with the click of a mouse.
The easiest way to add new communication capabilities is for the manufacturer to provide a module or kit that can be attached to existing equipment. This scenario is most common for manufacturers that still make and support similar equipment.
Offering the ability to monitor such equipment is a requirement for new devices. If you already have numerous ABC Air Conditioners installed and monitored, then it is likely that you will purchase new equipment from the same vendor so that you can continue to monitor in the same way that you already monitor older equipment. In some cases, the original manufacturer has no incentive to produce the hardware necessary to create a digital connection to existing equipment.
However, a third-party may choose to create such hardware. Often, a company that offers ongoing support or other services would choose to create the necessary hardware and then sell it or offer it as part of a service contract. In one example, Bosch Rexroth, a third-party company that sells an IoT gateway, connected a lathe from to a sensor that monitored and recorded its speed.
