Carbon Dioxide(CO2) Dual Sensor Module (D-300)

1. D-300 (5V Model)

D-300(LG) series is the smallest Dual CO2 sensor module in the world. Its Persistent Stability and Temperature Effect Resistance are much favored in warehouse, greenhouse, hospitals etc. besides the small size and consistent accuracy through the life cycle.
