Semiconductor maker STMicroelectronics will unveil an application for mobiles or set-top boxes, taking utility of an open platform for buildings. The GreenNet Wireless Sensor Networking technology platform comprises self-powered nodes that can be positioned around the home for tasks such as temperature, CO (carbon monoxide) or movement sensing, relaying data wirelessly to a GreenNet dongle installed in a PC or set-top box. The data could then be communicated to a mobile device such as a smartphone or tablet via a wireless router to enable monitoring and control. The building block of this GreenNet Wireless Sensor Networking platform is the GreenNet node, which utilises core ST technologies in energy management, silicon-based sensors and embedded wireless to create the network node free of wires or any need to change batteries. The node combines a rechargeable battery and solar cell with an on-chip sensor and STM32W 32-bit wireless microcontroller in a compact 3D system-in-package that consumes minimal power and can operate autonomously powered only by ambient light energy. By using open standards, such as IPv6 1, the platform allows independent developers to create downloadable applications for tasks such as home monitoring, security or fire safety. The GreenNet wireless node utilises an industry-standard IEEE 802.15.4 radio operating in the license-free 2.4GHz frequency band. ST is demonstrating the system using a sample node that features an on-chip temperature sensor, a USB dongle, and a service platform including sample application store. It can relay one temperature measurement every five minutes. It can still operate autonomously for up to six weeks in the da rk. Samples for customers are available.
