CYTHS

A 433 MHz Temperature and Humidity Solution

This project is divided in several parts:

• A sensor which measures and sends temperature and humidity

• A hardware part connected to a Raspberry Pi in order to:

  • Receive sensors information
  • Drive RSL switch connected to electric heaters

  

• A software part hosted by the Raspberry Pi which:

  • Drives RSL switches

    

  • Stores sensors data received

    

  • Allow to schedule RSL switches change

    

  • Allow to associate and dissociate switches

    

Hardware requirement

CYTHS works on Raspberry Pi

It has been tested on models:

• Pi 2 Model B

  Which was used during development phase

• Pi 3 Model B

  On this board Bluetooth has been added and connected to default UART

  To have it working you need:

  • Disable Bluetooth to restore default UART

    echo -e "\n# Disable Bluetooth to restore default UART\ndtoverlay=pi3-disable-bt\n" | sudo tee --append /boot/config.txt > /dev/null
    

  • Stop Bluetooth service

    sudo systemctl disable hciuart
    

  • Make sure you have console=ttyAMA0 in /boot/cmdline.txt

  • And reboot system: sudo reboot
