ALLNET 4duino Neigungs Schalter LM393 ZYMQ-2 MQ2 Gas Sensor Module Smoke Butane Methane Sensor For Arduino Product Description

Using high-quality dual-panel design, with power indicator and TTL signal output instructions The switching signal having a DO (TTL) output and analog output AO TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module ) Analog output voltage with the higher concentration of higher voltage. A gas, natural gas, city gas, smoke better sensitivity. There are four screw holes for easy positioning Has a long life and reliable stability Rapid response and recovery characteristics
