Product Name: micro carbon dioxide sensor

Product model: S-300

The S-300 output interface is fully compatible with S100 and S200, and can also provide other output modes, such as PWM and alarm mode, selection more abundant. Which S-300L supports sleep mode (<0.5mA), can be used for battery; S-300G is suitable for agricultural wet environment, such as green greenhouse.

Main features:

– optional output mode: Alarm, I2C, AVO/PWM, UART

NDIR infrared detection principle

– the sensor can be periodically self correction with ACDL function

– sensor size: 33mm x 33mm x 13mm

Environment of use:

Work humidity range = > 0 ~ 95% RH (Non-condensing)

Working temperature range of ~50 DEG C = > 0 (expansion: -20 ~60 OC)

Storage temperature -30 ~ 70 DEG C = >

Working parameter:

Detection principle = > NDIR (non dispersive infrared)

– the detection range of 0 ~ 2000/3000/5000/10000 = > ppm (optional)

2% to 3%, 5%, 0 Vol. (optional)

– to 10000ppm: detection accuracy = > 0 + 30ppm + 3% readings

3%, 5%, 2% Vol.: + 3% reading

Response time (90%) = 60 seconds

– sampling interval = > 3 seconds

Electrical parameters:

– input power =>5.0V 5%

– power consumption: 25mA = > Normal, Max: 330mA, Sleep: 0.5mA

Output connector (2mm = > 4pin/10pin Pitch Socket Side pin), hole output (6pin, 13pin)

Output:

– digital interface 38400BPS = > UART-, 8 bytes, no parity, 1 stop bit, TTL level

Analog output 0.5 ~ 4.5V = > VDC (linear output)

I2C = > main mode

– PWM=> 2 ms_High: Start, 2000 ms: ppm, Low 998ms: Stop

Alarm=> 1000 ppm ON 800 ppm = Alarm, OFF = Alarm
