US20210108817A1: An HVAC controller, such as a thermostat, may be configured to allow a user to set and/or select a scheduled time period in which one or more indoor quality units (e.g. humidification, dehumidification, ventilation, etc.) will or will not operate, and/or will operate but using different settings. In some cases, the scheduled time periods available for selection may correspond to the time periods of a programmable temperature schedule of the HVAC controller, but this is not required. In some instances, the HVAC controller may allow a user to select which indoor air quality units will or will not operate, and/or what settings the indoor air quality units will operate, during a user's vacation.

SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts, in a simplified format, which is further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention nor is it intended for determining the scope of the invention.
To further clarify the advantages and features of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof, which are illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail in the accompanying drawings.
Nowadays, poor oxygen levels over time make it difficult for our body to function at its highest level. One of the worst symptoms poor indoor air quality can have on you isn’t just a headache or upset stomach it’s fatigue. When we sleep with poor oxygen levels, then poor oxygen levels will drastically decrease our energy level. Thus, this invention proposed an IoT based indoor air quality monitoring system. It can detect harmful gases like smoke, carbon dioxide, etc. using inbuilt MQ2, MQ137, MQ303A, and MQ309A sensors.
BRIEF DESCRIPTION OF THE DRAWINGS
The illustrated embodiments of the subject matter will be understood by reference to the drawings, wherein like parts are designated by like numerals throughout. The following description is intended only by way of example and simply illustrates certain selected embodiments of devices, systems, and methods that are consistent with the subject matter as claimed herein, wherein:
Figure 1 illustrates the IoT based air quality monitoring system which is used to detect harmful gases comprising of an MQ2 sensor (101), which will be sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke, and carbon monoxide. This sensor contains a sensing element, mainly aluminum-oxide based ceramic, coated with Tin dioxide, enclosed in a stainless-steel mesh. The sensing element has six connecting legs attached to it. Two leads are responsible for heating the sensing element, the other four are used for output signals. An MQ137 sensor (102), is an ammonia gas sensor that detects the presence of ammonia gas. As the concentration of N gas rises in the air, the conductivity of the sensor tends to become higher. Using a circuit, you can convert this change in conductivity to the output value which indicates the concentration of a gas. Along with ammonia gas, it can detect organic amines also. MQ303A (103), for detecting Alcohol, Methane, Hexane, Carbon monoxide, and liquified petroleum gas (LPG). The sensor contains tin dioxide when the alcohol gas exists around, the conductivity of the sensor is higher. MQ3 gas sensor has an acute sensitivity to Alcohol and has excellent \resistance to disturb smoke, vapor, and gasoline. MQ309A (104), MQ309A is a tin dioxide semiconductor gas sensor that has an excellent performance in detecting both CO and Methane. It is a miniature sensor that adopts changing working temperature periodically to detect with high sensitivity and selectivity, the humidity has little influence on it, Exhaust fan (110) here fan is used for Air purification whose purpose is to maintain the air quality of the house, display (108) is used to display all the information about all the air quality contaminants, Wi-fi connects all the components of the system.
