+* Motion activated temprature and humidity measuring  using humidity and PIR sensor.
+* while measuring it will notify the sourunding by blikinking LED and making buzzer sound. 
+*  The measuured data is sent to  Thingsspeak cloud server
+*--PIR Motion Sensor Alarm + ESP8622 WiFi Module + FRDM-k64f
+* --PIR sensor can detect change on its surrounding by measuring the change of infra red
+* --Then will send high=1 to the FRDM-k64f to flash the LED, Run the Buzzer,
+* --Send information through UART serial Port to Tera Term and display how many motion been
+*---detected,also will send information to Thingspeak IoT website using WiFi connection
