This video shows how to make a Temperature and CO2 Alert Robot to spin to warn users when it gets too cold, too hot or there is CO2 in the area. For this proof of concept demo, if the fan blows on the temperature sensors to lower the ambient temperature then the robot spins clockwise. If you blow on the sensor to release CO2 then the robot spins counter clockwise. Some ways to enhance the project would be to add a buzzer for distinctive sounds for each threshold and also add LEDs indicators.
