S-300 SeriesCO₂ Sensor Module
CO2 Smallest sensors module
S-300 series is one of smallest CO2 sensor modules in the world. Its Persistent Stability and Temperature Effect Resistance besides easy management are much favored by customers in stocks raising, greenhouse, scientific projects, etc. S-300-3V is much favored by customers whose application needs 3.3Voltage input and sleep mode support so on.
