Ammonia Sensor. - Sensors - Arduino Forum

· The ammonia gas sensor you looked at will meaure ammonia in air, and it is less sensitive than your nose is. 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.

How To Use MQ-135 Gas Sensor - Codrey Electronics

· In this sensitivity characteristic curve (borrowed from the datasheet), Ro is the sensor resistance at 100ppm of NH3 in clean air, and Rs is the sensor resistance at various concentrations of gases. If you want to do anything serious with MQ-135 gas sensor, then you should learn to analyze this plot pretty well. However that needs some skill and patience as the scale is log-log in a ...

NOx Sensors - DieselNet

Abstract: Automotive NOx sensors are primarily of the amperometric type, with two or three electrochemical cells in adjacent first cell electrochemically pumps O 2 out of the sample so it does not interfere with the NOx measurement in the second cell. Commercial sensors, available from several suppliers, are used for the control of NOx adsorber and SCR aftertreatment.

Resistor Capacitance | Resistor Fundamentals | Resistor Guide

Practical resistors always exhibit capacitance as a parasitic property. Depending on the application, resistor capacitance might be easily disregarded, especially in DC circuits. In some applications, such as snubber resistors, the capacitive parasitic effect is actually a desirable effect. On the other hand, parasitic resistor capacitance can ...

Dräger Polytron 7000 - Draeger

– Do not use a faulty or incomplete product. Do not modify the product. – If a pump module is used, care must be taken when opening the gas detector. Through an existing glass tube there is risk of breakage and injury. – If a pump module is used, do not block the lower gas inlet of the pump module. This can destroy the sensor.

Understanding a Gas Sensor | Jaycon Systems

· This resistor serves to adjust the sensor’s sensitivity and accuracy. The value can range anywhere from 2k Ohms to 47k Ohms. The higher the value, the more sensitive the sensor becomes. The value depends on whether you want to measure high concentrations of gas or not. If you choose to measure high concentrations of gas, but choose a high value for the load resistor, then the readings …
