Solid Electrolyte CO2 Sensor MG811

Summary:

MG811 electrolyte CO₂ sensor is a semiconductor oxide chemical sensor that uses the principle of solid electrolyte battery to detect CO₂. When the sensor is kept at a certain working temperature and placed in a CO₂ atmosphere, the positive and negative electrodes of the battery react with each other, an electromotive force is generated between the sensitive electrode and the reference electrode of the sensor, and the output signal voltage is inversely proportional to the logarithm of the CO₂concentration. The change of test signal voltage can detect the change of CO₂ concentration.

Feature:

* Good sensitivity and selectivity to CO₂
* Low humidity and temperature dependency
* Long 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.
