O2 sensor

NDIR, or Non-Dispersive Infrared, refers to a type of gas sensor technology that detects specific gases by measuring their absorption of infrared (IR) light at characteristic wavelengths. It is widely used for detecting gases such as CO₂, CH₄, CO, refrigerants, hydrocarbons, and other IR-active gases.

In recent years, agriculture has undergone a major technological transformation, often referred to as Smart Farming or Precision Agriculture. At the heart of this evolution lies the integration of smart sensors—advanced devices capable of collecting real-time data to optimize every aspect of farming.

Carbon dioxide (CO₂) is a colorless, odorless gas that is essential for life on Earth. It plays a crucial role in the carbon cycle, supports photosynthesis in plants, and is a major greenhouse gas contributing to climate change.

An industrial CO₂ sensor is a device designed to measure the concentration of carbon dioxide gas in the atmosphere. These sensors are essential in environments where CO₂ is a byproduct or where high concentrations of the gas may accumulate, posing a potential risk to human health, safety, and the environment.

Among the different types of CO2 sensors available, photoacoustic spectroscopy (PAS) sensors stand out for their high sensitivity and accuracy. This article explores the principles, advantages, applications, and future prospects of photoacoustic spectroscopy CO2 sensors.

As we spend a considerable amount of time in cars, it is essential to be aware of the air quality inside the vehicle. Carbon dioxide (CO2) levels can rise in enclosed spaces, including cars, and have potential implications for our health and well-being.

MH-Z19C has better consistency and performance than MH-Z19B, and can directly replace MH-Z19B.
