Alarm kits with Wi-Fi connection

Wi-Fi

— a technology used primarily for building wireless computer networks, and more recently also for direct communication between individual devices. For communication, the most commonly used band is 2.4 GHz or 5 GHz. In the case of wireless sensors, one of the advantages of Wi-Fi is that it is an accepted standard; thanks to this, many sensors with this type of connection can work without special equipment — they are able to connect to ordinary wireless routers or even separate devices like laptops and tablets (some models even allow notifications to be sent via the Internet, through the same router). However, this versatility has a downside: Wi-Fi does not have additional optimizations to work with wireless sensors. As a result, such communication is inferior to specialized protocols in terms of overall reliability, special functionality and energy efficiency. So this type of connection is typical mainly for devices designed for simple application conditions — such as climatic temperature / humidity sensors for smart home systems.
