MQ135 Sensor - calibrate and configure - DIY Projects

· MQ135 Sensors are usable as an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2 . For me, these sensors should be affordable by the price but also deliver acceptable measurements. That’s the reason I decided to test this MQ135 Sensor. Five of them are available in our region even with amazon for 11€ which make these little …

(NH3) Ammonia Gas Detection | Sensidyne

Sensor spacing is determined by the specific hazard locations and the subsequent dangers presented to local personnel. Ammonia Sensor ranges of 0-50 ppm, 0-100 ppm and 0-500 ppm can be supplied. Some users prefer to use a few 0-500 ppm sensors, as levels at or above the IDLH (300 ppm) will be indicated, and appropriate clothing and respirators can be selected by the emergency response team.

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

· Turns out that MQ137 sensor can measure NH3, C2H6O and even CO. But, here I am interested only in the values of NH3. However you can use the same method to calculate ppm for any sensor you like. This graph is the only source for us to find the value of ppm and if we could somehow calculate the ration of Rs/Ro (X-axis) we can use this graph to find the value of ppm (Y-axis). To find the value of Rs/Ro we need to find the value of Rs and the value of Ro. Where Rs is the Sensor …

Ammonia (NH3) detection in industrial area - Arduino Forum

· Hi everyone, I am planning to make a compact portable construction based on Arduino, LCD screen and ammonia sensor (for examble MQ137) in order to detect ammonia leak in a big industrial room. In this room there are pipes and machines that use ammonia and sometimes there is leak of ammonia due to various reasons. The result is that bad smell of ammonia that leads the factory …

Experimenting with Gas Sensors and Arduino | olimex

· MQ-135 is sensor of NH3, NOx, Alcohol, Benzine, Smoke, CO2 and can be used for quality of air analizer. We did some experiments today with all four sensors connecting them to OLIMEXINO-32U4 (Arduino Leonardo compatible). The sensors have 4 pins: AO – Analog Output, DO – Digital output, GND, VCC-5V. OLIMEXINO-32U4 should be switched to work ...

Atmospheric Air Analyser - Arduino Project Hub

While hardware for sensors and their connectivity with Arduino Nano is not quite surprising and is fairly common, the Interface between Arduino Nano and NodeMCU might be intriguing to a few. The objective here was to ensure that the device be cheap and should have connectivity to the internet. The necessity of Arduino Nano arises when data from sensors is to be sampled. The gas sensors output ...

How To Use MQ-135 Gas Sensor - Codrey Electronics

· yassin: RLOAD 10000 is for 1oK Load Resistor! As clearly pointed in this post, while using the “MQ-135” library-supported Arduino setup, the gas sensor calibration can be done at by finding the value of Ro in fresh air, and then using that value to find Rs through the formula: Rs = (Vcc/VRL-1)x RL, that means Rs = (5V/(sensorValue * (/))-1)*RL.

Yes, That is my ideas, I want to determind the total concentration of ammonia in aquarium water. It consists of NH3 and NH4+. As I know, to determind the concentration of NH3, we have to measure the pH and total concentration of ammonia.
