Wireless Control Smart Switch for Electrical Appliances


Client requirement was to develop the IoT based device, which can control the on-off of any electrical device at home by using wireless technologies. The device is connected to the internet via wi-fi, and access through the smartphone application.


We implemented the wireless controlled switch for all electrical appliances. Using mobile phone interface, users can remotely control the appliances by turning them, on/off from anywhere at any time.

Features of the Application

  • Control the home Electrical appliances from anywhere with your smartphone app.
  • Real-time device status provided to App
  • Turn on/off a gang of devices with one tap
  • Set scheduled/countdown/loop timers to turn on/off at specified time
  • Triggered on/off by temperature, humidity or other environmental conditions

Technologies used:

  • IoT technology.
  • Wireless technology.
  • Embedded technology.

Technical Specifications of the Device:

  • Voltage range: 90-250v AC(50/60Hz)
  • Max current: 10A
  • Max Wattage: 2200 watts
  • Operating Temperature: 0ºC-40ºC(32°F-104°F)
  • Operating Humidity: 5%-90%RH, Non-condensing
  • Wireless Frequency: 2.4 GHz.

Hardware Design Units:

  • ESP8266 Wi-Fi Module(802.11 b/g/n)
  • Relays(230V, AC supply)
  • LEDs

Software Requirement:

  • Android Application
