This is an Analog output sensor and needs to be connected to any Analog socket including the Universal Base Modules Socket. The output voltage from the Gas sensor increases when the concentration of gas increases. The sensitivity can be adjusted by varying the potentiometer.
Module Features :
Uses high-quality dual-panel design, with power indicator and TTL signal output instructions.
The switching signal has 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 detector with better sensitivity.
There are four screw holes for easy positioning.
Product dimensions : 32 (L) x 20 (W) x 22 (H)
Has a long life and reliable stability.
Rapid response and recovery characteristics.
