what's your gas sensor output signal?
what's your ultrasonic sensor output signal? Electric frequency signal, high level 5v, low level 0v. Detection distance: 2cm~450cm. Trigger Pulse Input. Echo Pulse Output
what's your gas sensor output signal? Has a DO switch signal (TTL) output and AO analog signal output. DO output: TTL digital 0 and 1 (0.1 and 5V). AO output :0.1-0 .3 V (relatively clean), the highest concentration of voltage around 4V. The analog output voltage, the higher the concentration the higher the voltage. For gas, natural gas has better detection sensitivity.
