+====== 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! :)
