Please download the Android App and follow the steps as shown in Figure 8 & 9.ДЇigure 9.3-pack of continental Europe and Middle East adapter plugs. User can also see the metering parameters using the same application. RF Smart Plug State Machine Android Application:ДЄn Android Application designed by STMicroelectronics can be used to Turn On/Off the Load, Scheduling and Dimming features. Figure 5 is showing the status of AC voltage at 50% duty cycle and use of ZCD for dimming reference point to fire the TRIAC.ДЇigure 5.TRIAC at 50% duty cycle and ZCD Working of RF Smart Plug:ДЇigure 6 is explaining the GATT and GAP role whereas Figure 7 is describing the State Machine of the RF Smart Plug.ДЇigure 7. In addition, they are also able to change the duty cycle of the AC voltage which is applied to the lights/load being controlled. It gives AC switching for various electrical system applications. The Satechi aluminium multiport adapter V2 is one of the best USB-C adapter hubs on the market right now. TRIAC is a three terminal component that is used to control the current. TRIAC and Zero Crossing Detector (ZCD) Operation: LDO LD3905 having output voltage and current are 3.3V and 500mA is used to power up all the analog and digital sections. In our design, Output of supply is set at 4.5 V. This type of supply are ideal for the applications (like Smart Plug) where large current is not needed and small form factor is required. It is used with PWM operation at 30 kHz with frequency jittering for lower EMI, having standby power < 30 mW. Non-Isolated buck converter (Refer Figure 4) is designed using VIPER06Xs. Description of some other sections is as below: In this design, all challenges related to form factor and reliability have been taken care. Power consumption of device is in between 40 to 50mA.ДЇigure 3 is showing all the sections of RF Smart Plug. This application is running at 48 MHz for performance operation of device. With the help of TRIAC user can control the load whereas Isolated USB port and dual EEPROM (M24LR) are available to communicate with GUI (Graphical User Interface) and NFC (Near Field Communication).ДЎ) In first mode device acts as BLE peripheral device which can be connected for control along with monitoring.Дў) In second mode device is a manufacturer specific beacon which is connectable and advertises its metering parameters so that multiple android smart phones can monitor the plug, but only any one of bonded device will able to connect.
