Solid Electrolyte CO2 Sensor MG812
Summary:
MG-812 is a semiconductor oxide chemical sensor that uses solid electrolyte battery principles to detect CO2. When the sensor is kept at a certain working temperature and placed in a CO2 atmosphere, an electrode reaction occurs between the positive and negative electrodes of the battery, and the output signal voltage is inversely proportional to the logarithm of the CO2 concentration. A voltage change in the test signal can detect a change in the CO2 concentration.
Feature:
* Small sizes
* Low power-consumption
* High sensitivity and good selectivity
* Less affection by temperature and humidity
* Good stability and repeatability
APPLICATION
Compared with traditional agriculture, greenhouse planting is an intensive industry. In the current greenhouse projects, the main economic crops are vegetables, flowers, medicinal materials, etc. For agricultural planting, greenhouses can provide a relatively stable and controllable planting environment to improve the stable yield and quality assurance of crops. At the same time, greenhouse planting can also achieve mechanized control and reduce labor costs.
The World Health Organization's "Indoor Air Pollution and Health" pointed out that the current level of indoor air pollution is 5-10 times higher than outdoor pollution, and 4% of global diseases are related to indoor air quality, and about 2 million people die prematurely each year from diseases caused by indoor air pollution.
