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

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

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

Temperature sensor

• Its model number is DS18B20.

• Measures temperatures from -55°C to +125°C.

• Power supply range is 3.0V to 5.5V

Magnetic door sensor(MC-31)

Switch Type: NO circuit is connected when magnet is near the switch.

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
