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

Smart Agriculture Greenhouse

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.
