παιδια λιγο την βοηθεια σας διοτι εχω απογοητευτει...οταν τρεχω αυτον τον κωδικα απο τον υπολογιστη μου συνδεδεμενο με καλωδιο με το arduino ολες οι τιμες τυπωνονται κανονικα στο μυνημα που μου ερχεται...'#include "DHT.h"

οταν ομως δινω ρευμα στο συστημα μεσω χρονοδιακοπτη απο μπαταρια τοτε τυπωνονται ολες οι τιμες στο μυνημα εκτος απο το σημα του gsm....δηλαδη στην τιμη signal = (εδω δεν παιρνει τιμη ειναι κενο)....τι μπορει να φταιει???οποιος μπορει ας βοηθησει..ευχαριστω
