Features:

- CO2 Module: Model SH-300-DC(Dual sensor).

Description:

- NDIR Dual CO2 sensor (SH-300-DC).
- Detected value of single sensor can be easily changed as time goes by.
- Whereas dual sensor’s detected values can not be hardly ever changed, because dual type sensor has two sensors inside of module.
- One is CO2 sensor and the other is reference sensor and the band gap between CO2 and reference always keep same width.
- Therefore, many companies and R&D center prefer Dual sensor in these days.

Features:

- DUAL Type NDIR (Non-dispersive Infrared) Sensor.
- Support both analog and digital output.
- Analog output: 0~3V (0~3000ppm).
- Digital output: UART (3.6V Level RS-232) output
- Enable to make changes in specifications and protocol on customer’s demands.
