IoT Room temperature control project

This project aims to keep room at a stable temperature that can be change by user. Project has 4 parts and these are

• Web API | .NET 6 C# - Docker support
• Center ESP8266 device that connects WiFi(API), measure temperature by DHT22, sends RF 433mhz signals to other device to turns on/off heating system | Arduino C/C++
• Arduino (any) device that receives command via RF 433mhz from center and turns on/off the heating system | Arduino C/C++
• Simple Android application that users can login, control temperature or manually turns on or off | Native Android - Kotlin

Necessary devices:

• ESP8266 based board (NodeMCU, D1 Mini etc.)
• Arduino based board (Arduino Uno/Mini/Pro etc.)
• DHT22 Temperature/Humidity Sensor
• Any RF433Mhz Transmitter/Receiver (Must be compatible with ASK.h) (I try all rf433mhz sets and my choice is STX882/SRX882)
• Standard Relay module

TODOS:

• Add circuit diagram
• Add project design diagram
• Develop weekly scheduled control (with RTC module)

Center Device -> Connected to WiFi, measures temperature and send commands to Heater device via RF

Heater Device -> Receives Turn on/off commands via RF and controls Relay
