How to Choose a Methane Sensor for Monitoring Concentration NEAR the LEL
Monitoring of methane levels is largely driven by the range in concentration of methane you are trying to detect. Detection of methane near the lower-explosive-limit (LEL) is obvious since exceeding the LEL can be extremely dangerous. Most of the commercially available solutions focus on this methane concentration level. In this post I want to highlight some of the current options for detection of the LEL that are commercially available.
How to Choose an Off-the-Shelf Methane Sensor Module
There are various methods for measuring the presence of methane gas. My favorite is the laser-based absorption spectroscopy method. That’s what my PhD is in. Sometimes though, there are simpler “off-the-shelf” methods for measuring this invisible, naturally odorless, and valuable gas resource. The table below contains a list of commercially available sensors you can use …

Using AI Tools for Measuring Atmospheric Methane
TLDR: A dataset of simulated absorbance scans and a 1D convolutional neural net were used to train a model to predict methane mole fraction to within 0.25% of actual mole fraction. This provides the potential to rapidly improve data processing of TDLAS-based sensors. 1. Initial Absorbance Simulation We start with simulating methane absorbance. By using …

Satellite Based Methane Emissions Monitoring
Quantitative monitoring of methane greenhouse gas emissions is becoming increasingly important as the effects of climate change are becoming harder to ignore.[1] In this series of posts, we will dig deeper into the challenges associated with accurately monitoring methane gas emissions. This being a worthwhile endeavor since methane gas emissions account for up to 10% of …
