Product features

The IoT Smart House simulates a smart home in which everything is connected. From a phone or web page you can view data such as light levels, indoor temperature, humidity, and door access status, and you can also control devices in the house such as the light switches and the alarm (buzzer). It has four built-in operating modes by default: Auto (A), Manual (M), Network (Q), and Setup (S).

Hardware overview
1. 2004 LCD module: a panel 20 characters wide and 4 high that can show 80 characters at a time. We will use the LCD to show data from the various sensors, and the function of each page can be planned in code.

3. Dual-axis joystick: provides analog X and Y values and a digital push switch. We will use these external inputs to interact with the system.

4. WS2812 RGB LED: a programmable RGB LED. We will combine it with the joystick, RFID, and light sensor to create interactive effects.

5. RFID reader: detects cards or devices that support RFID, such as iPASS, EasyCard, and NFC devices (phones).

6. DHT11 temperature and humidity sensor: senses ambient temperature and humidity. Its accuracy is not on par with professional sensors, but it is still a useful reference if you only need approximate values.

7. Light sensor module: senses ambient light intensity and outputs it as an analog value. We will use this value to control WS2812 brightness, simulating lighting that adjusts automatically with ambient light.

8. Flame sensor: detects flames and outputs a digital signal. We will combine it with the buzzer to simulate a fire alarm.

9. Buzzer: produces various musical pitches under frequency control. We will combine it with the surrounding sensors to create interactive effects.

10. Circus 7697D: a development board for IoT applications. It includes 2.4 GHz/5 GHz Wi-Fi and Bluetooth 4.2 Low Energy for wireless communication, so users can start writing programs right away without an external wireless module.

11. EzDIO expansion board: a three-in-one expansion board that works with micro:bit, LinkIt 7697, and ESP32 controller boards. It provides plenty of Grove sockets, which suits projects that connect multiple sensor devices.

12. Lipo Rider: provides a stable power output and uses a power management IC to charge the battery with power from the solar panel above.
