我的項目是：讀取溫度並通過SMS以10分鐘的時間間隔發送，並且在此範圍內運動，然後發送短信「MOTION DETECTED」。PIR傳感器連續檢測，因此循環計數器（「i」）可能不會遞增並且循環保持空閒狀態
如此，只是爲了測試我用了兩個LED一個溫帶（它將停留在10分鐘），SMS和其他的運動（它將閃爍一次）和評論功能的調用語句即的sendMessage，SENDMSG
一切工作正常，但問題是「當我長時間持續晃動我的手在PIR傳感器前面時，它持續檢測運動並且可能是計數器不會增加，因此不會增加，即第一次溫度超過10分鐘...，但如果我將我的手放在PIR傳感器前幾秒鐘以檢測Motion（儘可能多的時間），那麼它的工作正常......但對於持續檢測出現的問題，超過10分鐘。例如，持續30秒的連續檢測在10分鐘內停留30秒...... 1分鐘DLED停留在11mins ......」
這是問題希望我讓你們使它可以理解的...... 所以請幫助我..謝謝
這裏下面的代碼...
