Introduction The WHO reported that poor air quality caused million deaths in 2016, of which, primarily, 17% were due to strokes, 25% were due to COPD, and 26% were due to respiratory disease [1]. It is evident from many studies that the concentration levels of indoor air pollutants are two to four times higher than those of outdoor air pollutants [2–5]. In the , on ...
2019-05-23· In addition to getting the “big picture” of your indoor air quality, an indoor air quality monitor can be set up to provide threshold alerts. If, for example, the outside air has a CO2 level of 400 ppm, you could set up your monitoring equipment to alert you when indoor levels reach 950, and when the air has reached critical point at 1100 ppm.

2014-05-13· Carbon dioxide (CO2) sensors are increasingly used in areas of Indoor Air Quality (IAQ) monitoring and demand ventilation control. Insufficient ventilation rates …
This term encompasses health problems caused by the insufficient air quality in indoors of office buildings or schools. These problems include headaches, breathing problems, allergic reactions or trouble with maintaining focus. Indoor air quality is decreased by several risk factors, notably a high concentration of carbon dioxide, presence of volatile organic compounds (VOC), high/low air ...
The 2021 guide to Indoor Air Quality Monitoring (IAQ) A business analysis of indoor air quality standards and viral prevention. This document is for operations personnel and businesses new to indoor air quality monitoring. It breaks down a range of common concerns and recommends practical, low-cost solutions that companies implement and offer ...
environmental problems. Based on figures from the World Health Organization, million people die prematurely each year from illness attributable to household air pollution. Hence, it is essential to have good air quality monitor systems at the office and at home for constant air quality monitoring. The indoor air has major airborne contaminants, such as total volatile organic compounds ...
Trouble Shooting What the separate wires do in the interconnecting cables Note – Wires are 240V Live except where marked neutral or Earth or signal. Cables marked Signal are digital pulses and you should not attempt to measure these with a meter.

The average person spends an estimated 90% of their time indoors so that poor indoor air quality (IAQ) poses a substantial risk to public health. Poor air quality may cause increased short-term health problems such as fatigue and nausea as well as chronic respiratory diseases, heart disease, and lung cancer.
The technology. Just about every air purifier that has a built-in air quality monitor (including our own) uses a dust sensor like this one to detect particulate matter. These devices use an infrared beam and a sensor. Each particle that passes between the beam and the sensor absorbs a little bit of light, causing the beam to dim a little bit.
Indoor air quality also improves due to a reduction in the number of viruses and bacteria. Ventilating a room also reduces the number of particles occurring indoors. World Health Organization.
