Undoubtedly, sensor technology is playing a major role in realization of next generation of “Smart Homes”. The technology is foreseen as the basis for supporting the construction of home automation as well as Energy Management System (EMS). One of the companies who has been at forefront of this vision is Murata who just recently announced the development of sensor network system for smart homes which is capable of gathering information that has been detected by sensors via the ZigBee based Gateways, where it can transmit the gathered information via WiFi or Ethernet over the internet or to a tablet terminal. The system uses the Android-based controller. The new system is to perform detail control of lighting and air conditioning while monitoring power usage and environmental conditions such as temperature, humidity and lighting by using the sensors that are located throughout the home. In addition to this, as part of company’s effort in supporting the elderly in achieving a safe, peaceful and comfortable living environment, the network is capable of remote monitoring and preventing such incidents as heatstroke. The system provide a less environmental impact by combining energy harvesting technology and wireless communication with low current consumption.
SMK has announced the development of a remote control and receiver with company’s RF module which contains a built-in 2.4GHz band antenna compatible with ZigBee™ RF4CE1 for use in regular remote controls. The newly developed remote control is capable of N-to-N high reliability two-way communication, low power consumption, co-existence with other 2.4GHz band RF as well as security settings. The remote control comes in a form factor of 131mm x 58mm x 17mm and the receiver come in a dimension of 24mm x 16mm x 8mm. The receiver has a USB interface. The transmission distance is at minimum of 10 meter, with frequency range of 2400 to 2483.5MHz. The remote control has a supply voltage of 2.1 to 3.4 VDC, and for the receiver is 4.4 to 5.25 VDC.
