They can be attached to devices like air purifiers, vents, exhaust fans to automatically purify the air in a place. The MQ135 sensor provides the PPM which is in our surroundings, MQ2 CO sensor and MQ7 gives a signal if CO or any flammable gases are present. Node MCU is a cheap module which has WIFI built into it. 2 Node MCUs are used so that they can connect wirelessly as WIFI server and client and enable the wireless connection of sensors and LEDs which will represent door exhaust fans etc., Thing speak will be used to upload the data into cloud.
