air quality

The BME680 is an atmospheric sensor that measures four values: temperature, pressure, humidity and air quality as an IAQ index. Using that data can calculate elevation. It is really simple to use considering that it’s using I2C communication protocol and its dimensions are really small so it can fit anywhere. Everything you need to know about the atmospheric conditions and the quality of the air – you can find out using this sensor (ideal for weather station projects!) This board comes with two easyC connectors, providing easy connection to other products.

The CCS811 sensor is designed to measure various volatile particles in the air (TVOC – Total Volatile Organic Compounds), which include eCO2 (CO2 equivalent) and MOX (metal oxides). VOCs are generally defined as air pollutants, and can come from a variety of sources, starting with ordinary breathing, smoking, coloring, welding, and generally all processes that release particles into the surrounding air.

This sensor is often used to measure indoor air quality, which can work very well and indicate current air pollution, for example, in an office. It communicates via I2C, making it easy to connect, especially through easyC. Sensor itself should be powered for at least 20 minutes to start making accurate readings.

The MQ135 sensor’s versatility allows it to be used for applications such as indoor air quality monitoring, gas leakage detection, and environmental sensing. While its main target gas is carbon dioxide (CO2), it is also sensitive to a range of other gases including volatile organic compounds (VOCs), alcohol vapors, benzene, smoke, and other harmful gases commonly found in the environment. By integrating the MQ135 sensor with appropriate electronic circuits and microcontrollers like Dasduino, you can create systems that provide real-time monitoring and analysis of gas concentrations, enabling you to take necessary actions for maintaining a healthy and safe environment.

The breakout board works with both digital (DO) and analog signals (AO). The digital output is obtained by setting a threshold value with a potentiometer. The analog output will differ depending on the intensity of the gas.

The MQ135 air quality sensor module operates at 5V and consumes around 150mA. It requires some pre-heating before it could actually give accurate result.

The breakout board provides digital and analog information through the easyC system. Sensor readings are obtained through easyC.

Product usage tips:

When gas is detected, the LED will start glowing. It will remain off if it doesn’t detect anything. Four mounting holes enable easy mounting to surfaces. The board comes with three male headers.
