Naman Gohil, IUPUI ECE / Mbed 2 deprecated Motin_Activated_Temperature_Humidity_BluetoothHC-06_ESP8266_IOT

Motion activated temperature and humidity sensor is a project designed to implement the functionalities that FRDM K64F developmental board and software developmental platform offers on mbed complier. Such as: Peripherals that are enabled for prototyping different headers and functionalities.Bluetooth; Wi-Fi module (ESP 8266) which supports connecting the board to cloud storage; PIR, electronic sensor for detecting motion, sensor are incorporated to build the project. The communication of peripherals with the board is implemented on serial communication and ports configured for UART.

Dependencies:   DHT ESP8266 MFRC522 mbed

ndgohil 0:17278ea5a8b5 4 * while measuring it will notify the sourunding by blikinking LED and making buzzer sound.
ndgohil 0:17278ea5a8b5 5 * The measuured data is sent to Thingsspeak cloud server
ndgohil 0:17278ea5a8b5 6 *--PIR Motion Sensor Alarm + ESP8622 WiFi Module + FRDM-k64f
ndgohil 0:17278ea5a8b5 7 * --PIR sensor can detect change on its surrounding by measuring the change of infra red
ndgohil 0:17278ea5a8b5 8 * --Then will send high=1 to the FRDM-k64f to flash the LED, Run the Buzzer,
ndgohil 0:17278ea5a8b5 9 * --Send information through UART serial Port to Tera Term and display how many motion been
ndgohil 0:17278ea5a8b5 10 *---detected,also will send information to Thingspeak IoT website using WiFi connection
