DT-SENSE Carbon Dioxide Sensor is a gas sensor module to measure the carbon dioxe gas in the air. This module based on MG-811 which can be detect the carbon dioxed gas in range 350 - 10000 ppm. This module is well suited for air quality control application.

DT-SENSE Carbon Dioxide Sensor is designed using SMD component so this module has a compact size. This module provide two option for interface : 38400 bps UART TTL or I2C. Moreover, this module can be cascade up to eight modules by I2C interface.

Dimension : 5,6 cm (L) x 4 cm (W) x 3,4 cm (H)
