Specifications:
Input voltage: DC 5V
Power: 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
O output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V.
Suitable for home or factory gas leakage monitoring devices.
Have better sensitivity to Carbon Monoxide, Methane and LPG Gas.
High quality dual-panel design, with power indicator and TTL signal output instructions.
DO switching signal (TTL) output and AO analog signal output.
TTL output valid signal is low. (When the output low signal is on, it can be directly connected micro-controller or relay module.)
Analog output voltage: the higher concentration, the higher voltage.
