Meet roQar: a smart window that serves as a ventilator, purifier, and thermostat. It brings fresh air into your home and offers climate control to save you money in the long run. It gets rid of up to 90% of unwanted outside temperature. It can replace your AC when the outside weather accommodates.
roQar comes with various sensors, 2 STM32 microcontrollers, and an app for you to get started. It offers WiFi, Bluetooth, and IR support. The app lets you control humidity, fan, temperature, and other settings. Yet another interesting Kickstarter project.
