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
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.
