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 Piand Run the Program

Access your device from Devicehive Admin UIand 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: UpdateStateParameter: {"equipment":"LED","state":"1"}Create client App to switch on/off the LED and get temperature readings

Access your device from Devicehive Admin UIand 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?
