MQ-8 hydrogen gas sensor detects the alarm module, gas sensor module Arduino. ... MQ-136 MQ136 Semiconductor Sensor for Hydrogen Sulfide. 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 toxic.

I positioned the gas sensor on the side of the brush-like device for easy blowing.The temperature sensor is placed close to the gas sensor to measure the ambient temperature, as the gas sensor is sensitive to temperature. I designed a holder for the temperature sensor to be next to the gas sensor while being removable to measure body temperature.

These Arduino IDE compatible boards allow you to develop rapid, high quality prototypes or one-off designs you can use in the field. The Gas board series come with high quality EC gas circuits and ADC and are compatible with a huge array of EC cell gas sensors. Re: temperature and humidity correction via an Arduino sensor -- currently (8/21/12), the least expensive I can find are the DHT11/22 sensors for $5 / $12.50 on Adafruit. The sensors are almost identical except for the sensitivty; details via that link, but in summary:

Poe best leveling 70+Multiply decimals by powers of 10 worksheetA sensor array consisting of four individual gas sensors (methane, carbon dioxide, carbon monoxide, hydrogen sulfide, ammonia) has been developed for analysis of individual gases from a mixture of ... Deskripsi MQ-136 MQ136 H2S Sensor Module Hydrogen Sulfur Arduino Raspberry. Size: 32mm X22mm X27mm long X wide X high Main chip: LM393, ZYMQ-135 gas sensor Operating voltage: 5 V DC Characteristic: 1 signal output indication. 2 dual signal output (analog output and TTL level output) The output signal of 3 TTL is low. MQ136 Gas Sensor can be used to monitor the concentration Hydrogen Sulfide gas. This Module simplifies using the MQ-136 gas sensor by providing digital as well as analog output which can be interfaced to Microcontrollers, Arduino and Raspberry pi. Senitive material of MQ136 gas sensor is SnO2, which with lower conductivity in clean air.

The MQ-135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and smoke. The boost converter of the chip MQ-3 gas sensor is PT1301. The operating voltage of this gas sensor is from 2.5V to 5.0V. The MQ-3 gas sensor has a lower conductivity to clean the air as a gas sensing material.I have this Hydrogen Sulfide gas sensor and the datasheet says the supply voltage requires a regulated voltage with a min of 2.6v and max of 3.6v. I can't find any datasheet for the nodemcu v3 (spent hours looking, but none mention anything relevant) that's says whether or not the power output of the 3.3 pin is regulated (how can I tell?) but others have said an Arduino Uno's 5v and 3.3v ...
