IoT home automation project

The Smart Home Automation made by using Arduino and Cayenne as IoT middleware to control and monitor through a mobile app and the web from anywhere at anytime.
The system configured to send SMS and Email notification due to the reaction of smoke, temperature, magnetic door, PIR motion sensors.

7. Components datasheet It has 14 digital input/output pins (of which 6 can be used as PWM outputs) It has 6 analog inputs A 16 MHz crystal oscillator. Output voltage is 5v Input voltage 5-12v Arduino datasheet

8. Ethernet shield The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 Ethernet chip. LEDs: PWR : indicates board & shield are powered LINK : indicates network link & flashes when the shield transmits or receives data FULLD : indicates full duplex connection 100M : indicates the presence of a 100 Mb/s network connection (as opposed to 10 Mb/s) RX : flashes when the shield receives data TX : flashes when the shield sends data COLL : flashes when network collisions are detected

9. Passive Infrared Motion sensor Output : Digital pulse high (3V) when triggered Sensitivity range : up to 20 feet (6 meters) Power supply : 5V-12V input voltage

10. Temperature sensor Its model number is DS18B20. Measures temperatures from -55°C to +125°C. Power supply range is 3.0V to 5.5V

11. Magnetic door sensor(MC-31) Switch Type: NO circuit is connected when magnet is near the switch.

12. Smoke sensor Character Good sensitivity to Combustible gas in wide range High sensitivity to LPG, Propane and Hydrogen Long life and low cost Application Domestic gas leakage detector Industrial Combustible gas detector Portable gas detector

13. IoT MIDDLEWARE Cayenne is the world’s first drag and drop IoT project builder .  It help users create Internet of Things prototypes and then bring them to production. Cayenne was designed to work from IOS and Android smartphones and popular browsers. Cayenne is totally free. There are two components in the platform: Cayenne Mobile Apps  Cayenne Online Dashboard
