Touchless control sensor modules add multifunctional capabilities to LED lighting
August 23, 2012 // Julien Happich
Touchless sensor modules now available from Rapid Electronics, add multifunctional capabilities to LED lighting, allowing users to switch and dim lighting in response to hand gestures and proximity, without the need for physical contact.
Designed by German green technology specialist Fara, the 1-channel and 2-channel sensors operate by using IR technology up to a distance of 15cm. Passing a hand in front of the module switches lighting on and off; gesturing upwards with the hand performs the dimming function. On the 2 channel sensors, which provide 2PWM, the proximity function allows for differing colours to be mixed and reset according to hand gesture. Colour temperatures can be mixed and bespoke shades created.
When used in conjunction with LED lighting, the Fara touchless modules are well suited for health and medical environments, where a sterile atmosphere is a key requirement. They can also operate in bright sunlight and behind glass. No switches are required, and the modular nature of the technology means that all components can be used independently of each other.
Various options are available to tailor the system to specific requirements so that a configuration is possible for a wide range of applications, such as general lighting, light mixing modules, motor controls (e.g. exhaust hoods) and for usage in contaminated environments, such as the food industry, sanitary fittings or hospitals, waterproof switches, control of multi-channel systems via PWM or static outputs. The 2xPWM module is supported by a programming adaptor that enables the utilisation of seven different firmware functions such as dimming and colour mixing. A step down LED driver is available to drive a choice of LED modules with either white or white and amber LEDs. IR transparent covers are available for the sensor modules.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
