Battery Size Matters
Five fundamental considerations for a battery-powered, wireless IoT sensor product.
The Internet of Things (IoT) is upon us. Gartner recently reported a typical family home may contain more than 500 smart devices by 2022 (Gartner news, Sep 8, 2015). The promise is that every day home automation products will be smarter through the introduction of low-cost IoT technology including wireless transceivers and innovative sensors. But these features take energy, and a majority of these devices will be powered by batteries.
This presents an interesting challenge. To successfully design a product for the connected home, designers must generally build a small form-factor product, with the cheapest bill of materials (BOM), and reliable operation over several years without battery replacement.
