 +====== WeMos D1 + HTU21D ======
  
 +Úpravu skriptu od mikroma pro WeMos D1 s čidlem HTU21D provedl Martin Čapek [[Martin_Capek@seznam.cz]]
 +
 +<code c>
 +// Simple sketch for sending data to the TMEP.cz
 +// by mikrom (http://www.mikrom.cz)
 +// http://wiki.tmep.cz/doku.php?id=zarizeni:esp8266
 +// modify by Martin_Capek@seznam.cz
 +// If you send only temperature url will be: http://ahoj.tmep.cz/?mojemereni=25.6 (domain is "ahoj" and guid is "mojemereni"
 +// If you send also humidity url will be: http://ahoj.tmep.cz/?mojemereni=25.6&humV=60
 +// but for humidity You will need HTU21D or Si7021 (not tested) sensor and code will need some modifications
 +//
 +// Not tested, but should work! :)
