Arduino Ethernet Monitor Temperature Humidity Heating PHP MySQL

Monitor temperature, humidity, inputs and outputs in the home


System modules:

  • Module 1 - Flat - Recording 12x temperature (2x DHT22, 1x BME280, 1x SHT21, 8x DS18B20 [4x OneWire bus]), 4x air humidity (2x DHT22, 1x BME280, 1x SHT21) - communication via OneWire, I2C bus
  • Module 2 - Boiler room - 16x temperature recording (16x DS18B20 [7x OneWire bus]), 8x digital input (5V), 8x digital output (5V) - communication with sensors over OneWire bus
  • Web Interface:

  • The modules are integrated into a web interface where module data is visualized by the user together with the login system.
  • The web interface allows storing data from individual modules to the MySQL database.
  • The user can change the names of the rooms where the sensors are located on the page.
  • The outputs can be controlled in manual and automatic mode based on the target temperature from the control thermometer.
  • The outputs allow control of the radiator solenoid valves via a relay.
  • The web interface visualizes measured data in 24 hours, 7 days, visualization of maximum, minimum, average values in 24 hours / 7 days.
  • The source code for each Arduino Mega 2560 module and microcontroller is stored in the web interface and accessible to the logged-in user.
  • Arduino communicates with the web interface via the Wiznet W5100 Ethernet shield over HTTP protocol and sends data to the web interface using the POST method.
  • The modules operate independently of each other. Failure of one module will paralyze only that module, not the entire web system.
