ماژول سنسور تشخیص گاز هیدروژن MQ-8

Description:
This is a simple-to-use hydrogen gas sensor, suitable for sensing hydrogen concentrations in the air. The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm. This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance.
The voltage of the analog output is higher. The higher the concentration, the higher the voltage.

Application:
monitoring devices for hydrogen leakage in the home or industry

Features:
 using high-quality double-panel design, with power indication and TTL signal output indication
with DO switch signal (TTL) output and AO analog signal output
TTL output valid signal is low
Good sensitivity to hydrogen detection.
product dimensions: 32 (L) * 20 (W) * 22 (H)
Input voltage: DC5V Power consumption
current : 150mA
DO output: TTL digital quantity 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relatively non-polluting), the highest concentration voltage is about 4V
