5. Power

Power considerations need to be made when connecting a product to the IoT. Products already using a wall outlet will not have an issue. Manufacturers of products not using a wall outlet will have to consider how their power source will affect their product’s design.

IoT devices running on batteries will have to make hardware decisions based on power conservation. There are also a variety of different types of batteries to be taken into consideration: alkaline, lithium (rechargeable) and coin. There are also AA, AAA, coin cell, C, D, 9V, or custom batteries to choose from. As noted earlier, wireless technologies have different power requirements based on use-cases. Once a manufacturer understands how long and how often a device will be connected and the wireless network is chosen, a properly sized and type of battery can be chosen.

Another source of power for Ethernet-based devices is Power-over-Ethernet (PoE). This technology is popular for low-wattage IP phones and security cameras. Recent advancements and new switching technology is pushing the wattage available through PoE to new levels, thus opening up new possibilities for more power-hungry applications and devices.

6. Size

Many manufacturers start testing the IoT waters by modifying their existing product designs to add networking technologies. Because these devices already exist, many early entrants into the IoT world fail to redesign the product to allow for its newly added connectivity. Fortunately, there are a number of compact modules available for networking technologies that will fit in a manufacturer’s existing products.

These small modules are different though. Some modules are surface mount, others through-hole or pin-header and some still use a specialized mating connector. Also, how the network connector or antenna connector are integrated into the product vary from module to module. Designers must consider the space they have available on their circuit boards and/or in the product’s enclosures to allow whatever technology selected to be used in existing designs.
