Overview
• Motivation
• Block Diagram
• Prepare and Test the Circuit
• Installing DeviceHive on RaspPi and Run Program
• Access a device from Devicehive Admin UI and Create Client App
• Conclusion
• Future Work
Motivation
This project can be a very good starting ground, which it can be taken
further to allow a home owner to control, monitor and co-ordinate
home appliances remotely using the internet or remote device such as
mobile phone.
Block Diagram
Prepare and Test the Circuit
• Load Kernel module for auto load
• Access The Sensor
• Check whether the senor is working

Installing DeviceHive on Raspberry Pi
and Run the Program
Access your device from Devicehive Admin UI
and Create Client App
See the device and the readings from the sensor in Admin UI
http://nn5761.pg.devicehive.com/admin
Send on/off messages to the LED: Name: UpdateState
Parameter: {"equipment":"LED","state":"1"}
Create client App to switch on/off the LED and get temperature
readings
Access your device from Devicehive Admin UI
and Create Client App
Conclusion
Our internet-enabled temperature sensor and LED are now talking to
our JavaScript page using DeviceHive.
We just saved ourselves a bunch of time designing the protocol,
implementing libraries, troubleshooting and deploying.
Future Work
 Implement Client app to turn on/off and decrease/ increase the
The temperature.
 Replace LED with power relay and control light in a room,
 Add humidity sensor and light sensors to better monitor the
environment and report everything on your mobile device?
