Enocean Press Switch Circuit

Greetings,

The heart of the Enocean switch is http://www.newark.com/enocean/ptm215ze/push-button-transmitter-mod-2/dp/18AC0118  this will transmit the switch activations.

And the transceiver module that can receive this signal is http://www.newark.com/enocean/tcm515z/wireless-transceiver-mod-2-4ghz/dp/18AC0622

There is a pretty cool development kit http://www.newark.com/enocean/edk-350/energy-harvest-868mhz-developer/dp/98W2496

This stuff is pretty cool.  I have used a lot of enocean modules and developed a enocean to Zigbee bridge to use enocean switches in commercial lighting systems.  These parts are not really cheap, but what things are?

Hi,

My requirement is to just power two 5V DC LED circuits.

Range is not a problem as a radius of 2 meters is sufficient.

The design I am looking at is enocean sensor (piezoelectric) push button to reciever connected to arduino powering 2 output 5VDC LED circuits.

Would you reccommend Enocean as a low cost solution?

Thanks & Regards,

Deepak

Deepak,

The parts above could be used to do what you are referring to.  You need the piezoelectric switch (with transmitter), a receiver and then your arduino to light your LEDs.  This is not really a low cost solution, but if you can not tolerate a battery in your switch, this is about the only solution that you have.  The switch is ~$33.00, and the receiver is ~$16.00.  If you could tolerate the battery, or used a small solar cell to harvest energy to charge a supercap/battery, then you could use some of the very low cost ESP-01 like modules to broadcast your switch signal over WiFi  (there are a lot of examples using these parts here on element14 blogs/projects).

Thanks for the advise Gene.

Taking the cost into account, would you advise that Zigbee GreenPro or Z wave would be priced lower?

I am looking at 2 sensors and 2 recievers with a simple MCU to drive the LEDs to be under $50 for a college project.

Your suggestions would be helpful.

Thanks & Regards,

Deepak

Deepak,

There are so many ways to go.  What you are proposing it a very simple communication, so unless you need to, don't complicate it.  Zigbee is a very powerful mesh device with a high level of complexity and relatively high cost.  I would consider looking at something mush simpler.  There are some sub GHz band transceivers that are available for ~$1.00.  One of these paired with a small microprocessor (also ~$1.00) would make a simple solution to the design that you mention.  If you want to move to a slightly higher technology solution there are some Bluetooth transceivers available at ~$5.00.  These two could be paired with a small microprocessor to build either sensor or receiver.
