adi_22 Posted April 11, 2014 Share Posted April 11, 2014 Asa cum spune si titlul, doresc sa realizez in cadrul scolii de care apartin un contor digital cu Arduino de curent, in timp real. Astept pareri pro si contraq din partea voastra in legatura cu chestia care urmeaza s-o pun pe picioare. Mai jos aveti link-uri utile care va pot ajuta daca vreti si voi sa va faceti asa ceva, gasite de mine dupa cateva nopti de sapat prin adancurile Google-ului http://openenergymonitor.org/emon/buildingblocks/how-to-build-an-arduino-energy-monitor-measuring-current-only?page=1 http://forum.arduino.cc/index.php?topic=7837.0;wap2 http://openenergymonitor.blogspot.ro/2012/02/if-you-are-active-member-of.html http://www.desert-home.com/p/test-html-code.html Exemple de coduri: https://github.com/openenergymonitor/emoncms3/blob/a41c57d457df77697540b1a89a74486951e058ee/Models/process_model.php https://github.com/gysmovoile/emonTxFirmware/blob/master/emonTx_Interrupts/emonTX_Interrupts_EthernetAndLCD Quote Link to comment Share on other sites More sharing options...
radu_bc Posted April 11, 2014 Share Posted April 11, 2014 Unde vrei sa folosesti contorul? Ce curenti treci prin el? Daca vrei sa-l folosesti pentru o casa/un apartament, e cam greu de facut. Quote Link to comment Share on other sites More sharing options...
adi_22 Posted April 11, 2014 Author Share Posted April 11, 2014 Curentul maxim o sa fie atat cat o sa suporte si senzorul, 30A. O sa-l fac sa fie doar pentru prezentare, nu cred c-o sa-l folosesc acasa, poate doar o ora doua sa vad daca citeste la fel si contorul de la furnizor :freaza:De ce ar fi greu de facut?

radu_bc Posted April 11, 2014 Share Posted April 11, 2014 http://nicuflorica.blogspot.ro/2014/03/ ... tru-3.html Poti adapta programul de aici sa-ti masoare puterea si sa-ti faca o suma in timp... Sincer nu m-as juca cu arduino la 220VAC. Senzorii astia de curent sunt chinezarii la urma urmei... Bafta cu proiectul! Quote Link to comment Share on other sites More sharing options...
adi_22 Posted April 11, 2014 Author Share Posted April 11, 2014 Multumesc!Nu stiu daca ar putea afecta cu ceva avand in vedere ca masoara inductanta, eventual am sa-i caut o schema de protectie daca gasesc. Quote Link to comment Share on other sites More sharing options...
niq_ro Posted May 7, 2014 Share Posted May 7, 2014 (edited) modulele sunt chinezesti :banghead: dar ACS712 e ok ... e suficient sa te uiti in datasheet-ul lui: http://www.allegromicro.com/~/media/Files/Datasheets/ACS712-Datasheet.ashx (si cred ca textul asta e suficient:"2.1 kVRMS minimum isolation voltage from pins 1-4 to pins 5-8") eu l-am prezentat in 2 articolase: - http://nicuflorica.blogspot.ro/2013/08/senzorul-de-curent-acs712-i.html - http://nicuflorica.blogspot.ro/2013/08/senzorul-de-curent-acs712-ii.html Edited May 7, 2014 by niq_ro Quote Link to comment Share on other sites More sharing options...
moro Posted May 10, 2014 Share Posted May 10, 2014 Daca vrei precizie la masuratori te-as sfatui sa folosesti niste ADC`uri dedicate cu delta-sigma pe SPI sau I2C Quote Link to comment Share on other sites More sharing options...
cometa Posted May 13, 2014 Share Posted May 13, 2014 Poti incerca ceva de la Analog Device http://www.analog.com/static/imported-files/application_notes/an564.pdf . Bafta Quote Link to comment Share on other sites More sharing options...
