RY-VS09 10000 Ppm RS485 CO2 Carbon Dioxide Detector Sensor

The RY-VS09 CO2 sensor uses a CO2 probe imported from Sweden, with a wide range and strong antistatic ability. It converts the digital change of carbon dioxide content into analog current, voltage, or MODBUS protocol output for measuring ambient CO2 concentration. Widely used in meteorological environment, fresh air system, greenhouse cultivation, breeding, storage, scientific research and other fields.
