MQ135 Arduino library | Details |

01/01/2015· Because I guess that a general Arduino library for the MQ135 might be of use for other projects, I decided to split the software in a dedicated library and a sketch specifically for the SniffingTrinket. So, this is solely about the MQ135 lib, which, btw. you can find in my GitHub . First, some theory: My interest in those cheap gas sensors was sparked by a video from Ben Krasnow who takes …

Measuring PPM from MQ Gas Sensors using Arduino (MQ-137 ...

09/02/2018· The MQ gas sensors can either purchased as a module or just as a sensor alone. If your purpose is to measure only ppm then it’s best to buy the sensor alone since the module is good for only using the Digital pin. So if you have purchased the module already then you have to perform a small hack which will be discussed further. For now, let’s assume you have purchased the sensor. The pinout ...

Interfacing Force Sensing Resistor (FSR) with Arduino

Another key feature of the FSR is its rated sensing range, which defines the minimum and maximum pressures that the sensor can differentiate between. The lower the force rating, the more sensitive the FSR is. Any pressure beyond the sensor’s maximum range is unmeasurable (which can also damage the sensor). For example, a smaller 1kg rated FSR ...
