The Tuya platform combines the collaborative capabilities of multiple devices from different manufacturers in a single app and works on a cloud basis. This makes it possible to skip the fixed IP router and only need one app – Tuya Smart – to manage all the equipment, which can be used via the mobile network from anywhere.

UDP, or User Datagram Protocol, is a transport layer communication protocol in the OSI (Open Systems Interconnection) model. Unlike TCP (Transmission Control Protocol), UDP is a connectionless protocol, meaning that it does not maintain a reliable connection between sender and receiver.

A microbolometer is a variation of a bolometer, used in thermal imaging cameras. It is a device, which is, in a very simplified and generalized way, an ordered collection of pixels, which are a kind of thermistors, responding with a change in resistance to changes in the temperature of the observed object. The temperature information is carried by electromagnetic radiation in the infrared range. The microbolometer's electronics make it possible to create a "temperature distribution map," which is then interpreted by a graphics circuit that assigns a different color to each temperature.

USB-C is a 24-pin connector that replaces the previous USB Type A or B connectors. This connector can transfer audio, video and other data. It can also supply and receive power, e.g. to a camera, laptop, mobile phone, etc. It is not only used in the USB serial bus, but is also used by other protocols, including Thunderbolt, PCIe, HDMI, DisplayPort and others.

Wi-Fi 6 or IEEE 802.11ax is a standard that operates in the 2.4GHz and 5GHz bands, with an enhanced version of Wi-Fi 6E adding the 6GHz band. It is an update of the Wi-Fi 5 (802.11ac) standard with enhancements for better performance in crowded areas. It provides better spectrum utilization, better power control to avoid interference and enhancements such as 1024-QAM, MIMO and MU-MIMO for faster speeds. See more...
