2. Main functions:

2.1 The real-time display of CO2 concentration, temperature, humidity and present time, and the environment state by image expression (smile, uncomfortable and pain).

2.2 It records the information of CO2 concentration, temperature, humidity, present time and the maximum & minimum values (CO2 concentration, temperature and humidity) per day. 

2.3  User-definable detection range setting (0~10000ppm).

2.4  It supports PC data inquiry and function setting.

2.5  Pass code protection function

2.6 One-key input independent address 485 communications interface, communication rate 9600,14400,19200 (default),28800,38400 bps (programmable set), 15KV ESD protection, 8 separate address, the maximum number of network nodes 256;

2.7 Analog linear output and input of CO2 concentration:0.8~4V

2.8 User-definable alarm point (CO2 low-alarm, high-alarm; temperature low-alarm, high-alarm; humidity low-alarm, high-alarm).

2.9 Clock support for user set, and with a button battery, power-down without re-set time.

2.10 The sampling of CO2 concentration, temperature and humidity are high-performance modules with high-precision, low error, easy production debugging and post-maintenance.

2.11  External interfaces all use air plug to connect.
