CO2 SENSOR
RY-VS09
MANUAL

INTRODUCTION
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.
