Carbon dioxide sensor module
 |
S-300 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.
