Butterfly Mobile is an AC sensing device for collecting ambient room data to centrally control air conditioning units. The sensor collects data such as temperature, humidity, CO2 concentration, and human body temperature, which is sent to the control systems of the air conditioner, air purifier, humidifier, and ventilator. Besides providing an optimum ambient atmosphere for various scenarios (offices, schools, homes, etc.), the sensor reduces the environmental impact of AC and room climate devices by running these devices more efficiently and adapted to the size and configuration of the space being cooled.
