Our first prototype used a digital sensor for hydrogen sulfide connected to an #arduino. Advantages of this system is that data from the sensor could be logged over time and that tool is reusable and portable. However the Figaro TGS 825 sensor itself is relatively expensive--approximately $60 for an individual sensor and $40 in bulk.
2021-05-06· Has anyone used an ME3-H2S with their Arduino? I am looking for some guidance how to hook it up and get a reading. I am not concerned about converting the reading to PPM at this point so much as just getting a positive indication of the presence of H2S.
2020-10-09· The main objective of the work is designing Arduino based toxic gas detecting, alerting and protecting system. The hazardous gases like Hydrogen sulfide, Nitrogen dioxide and Carbon monoxide are sensed and displayed the status every second in the LCD display.
MQ2 Arduino Sensor is used to detect gas leakage of LPG, Butane Gas or Hydrogen Gas. Great with the project for safety purposes. MQ2 Smoke Gas Sensor Module is a general purpose gas sensor able to detect LPG, butane, methane, alcohol, hydrogen, and smoke. This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the gas concentration.
Sensors and their interfacing with Arduino Nano; Arduino Nano and NodeMCU interface; In this project, the Figaro TGS2600 checks for Methane and Carbon Monoxide, Figaro TGS2602 checks for Ammonia, Hydrogen Sulfide and Toluene while the less accurate and cheap MQ135 checks for Carbon Dioxide and NOx.

I bought a bunch of these and hooked them up to Arduino UNOs and placed them all over the house. Well believe it or not the first sensor to go off was not in my kitchen but in my attic and as hydrogen sulfide is a heavy gas I was in a quandary. So I had a look inside the roof to attic cavity and lo and behold the vent pipe did not go out onto the roof. This meant that the gas while heavy was ...
2017-10-16· Arduino code for the H2S sensor. Here comes the fun part: using the sensor with an Arduino board. I used one Arduino Due, as that board works with logic levels. The on;y thing to keep in mind is that the Due is a 32-bit board, and as such the int variable is 32 bit (ranges from -2,147,483,648 to 2,147,483,647). On 8-bit boards some readings will have to be recorded as floats. …
sensor currents into voltages proportional to the gas concentration. The sensor selected for this circuit is an Alphasense COH-A2 carbon monoxide (CO) and hydrogen sulfide (H 2S) sensor. Table 1 shows the typical specifications associated with this type of sensor. The gases that can be measured using this circuit and compatible sensors are ...

2019-04-18· To check the firmware version of the sensor one has to connect it to an Arduino Due or an Arduino Uno board, as described in my previous projects, and then run the SerialPassthrough Arduino sketch. Open serial monitor, then configure it to send only the carriage return. DGS-H2S — checking firmware version: Reset the sensor by sending ‘r ‘ or ‘R ‘. Then try to rapidly send several ...

2018-07-08· The official way to measure Ro is to measure the sensor resistance in a 10ppm concentration of the gas in air at 65% humidity and 20°C. Fortunately they provide a level for clean air. Looks like Rs/Ro is about for clear air so take Rs in clean air and multiply by to get Ro. Then you can use Rs/Ro to get rough approximations of ppm:
