· Hi Guys ! i am currently working on a water quality project, i am using mq135 sensor to detect nh3 or Ammonia present in an aquarium . i bought a windshield cleaner with ammonia for detecting samples, but the mq135 show 100+ value of PPM. can you give me ideas or better answers to display the right amount of PPM of nh3 ? Here's my code below. i know its kinda simple because i am …
· MQ135 Air Quality Sensor. The MQ-135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and MQ-3 gas sensor has a lower conductivity to clean the air as a gas sensing material. In the atmosphere, we can find polluting gases, but the conductivity of the gas sensor increases as the concentration of polluting gas increases.
· Arduino Code. Using the with Arduino is a simple matter of wiring up it to your Arduino-compatible microcontroller, installing the Adafruit PM25AQI library we've written, and running the provided example code. This code will get you started with any Arduino compatible ( Arduino UNO, Adafruit Metro, ESP8266, Teensy, etc.
· We will use MQ135 Air Quality Sensor that can detect the level of various air pollutants. Air Quality Index . The AQI is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. Think of the ...
