How To Use MQ-135 Gas Sensor - Codrey Electronics

2020-01-16· 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 linear scale, the behavior of the gas concentration with respect to the resistance ratio is exponential (not linear). For determining Rs/Ro, you can use the fact that the Rs/Ro ratio is a constant in ...

Tank Sensors - Water and Holding Tanks - FMCA RV Forums ...

2014-01-30· The general theory behind any sensor where some part of the sensor enters the tank itself is that the bottom most sensor would not provide any reading (empty) until the water level rises enough to touch the probe above creating a circuit. When the water level creates a circuit between the bottom (ground or power) sensor and the one directly above your gauge would read 1/4 (or lowest option ...

Troubleshooting Oxygen Sensors - Walker Products

These sensors must rely solely on hot exhaust gas to reach their operating temperature, and are designed to let a large amount of exhaust make contact with the active ceramic element. Heated oxygen sensors are less prone to contamination, as their internal heat source allows them to be placed much farther downstream than unheated sensors. Heated sensors should be inspected or replaced every ...
