Using high-quality dual-panel design, with power indicator and a TTL signal output instructions;
With DO switching signal (TTL) output AO analog signal output;
TTL output high and low. (Can be directly connected microcontroller or relay modules)
Analog output voltage change with concentration.
Liquefied petroleum gas, natural gas, city gas, smoke better sensitivity.
There is a screw hole for easy positioning;
With a long life and reliable stability
Rapid response recovery characteristics electrical properties: Input voltage: DC5V power (current): 150mA the DO output: TTL digital 0 and 1 (0.1 and 5V) AO output: analog level signal to remind: the sensor is powered, need to warm about 20S, measured data becomes stable, heat sensor is a normal phenomenon, because the internal heating wire, if not normal hot a. Wiring: 1, the VCC: positive power supply (5V) 2, the GND: power supply is negative 3, DO: TTL switching signal output 4, AO: analog output
