Module Features:
Using high-quality dual-panel design, with power indicator
and a TTL signal output instructions;
DO switching signal having (TTL) output and analog output AO;
TTL output valid signal is low. (When output low signal light,
can be directly connected microcontroller or relay modules)
Analog output voltage with the higher voltage, the higher
the concentration.
For carbon monoxide detector has good sensitivity.
There are four screw holes for easy positioning;
Product Dimensions: 32 (L) * 20 (W) * 22 (H)
Has a long life and reliable stability
Quick response and resume

Electrical properties:
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output: about 0.1-0.3V (relatively clean), the highest
concentration of voltage 4V
Special note: After the sensor is energized, needs to warm
up around 20S, measured data becomes stable, the sensor
fever is a normal phenomenon, because the internal electric
wire, if not normal hot
