He got it ...Just got similar device from my friend. He got it as a gift when he ordered some magazine.<br />Difference is that it only has its own memory where kWh count is stored. It also calculates the cost of used kWhs.<br />No nice graphs.<br />But maybe I use the sensor for Arduino! After they first bring new kWh meter to replace mechanical meter now in use.<br /><br />Well Arduino is nice. I have several of them in use at house.<br />Next you have to add some temperature sensors inside and outside to see how temperatures effect to amount of used electricity.<br />After that you may start to think how you can capture light reflection from water meter's "propeller" that spins in the middle of mechanical meter.<br />And still you have many inputs of Arduino free.<br />Maybe humidity, LDR to analog input to capture outside light level, wind speed and direction...<br />And still there is unused power on Arduino... endless project.<br /><br />My latest innovation is chrstmas lights.<br />4 red DIY lasers and servo motor from dx.com. Arduino blinks lasers randomly and turns them up and down with servo motor.<br />Box must be at least 3m height so that no one will look to lasers.<br />And where are they pointing to? <br />To my 24m antenna tower. I have now up/down (between 12m to 24m) running christmas lights without climbing to tower!OH1KHhttps://www.blogger.com/profile/15108609251666517076noreply@blogger.com
