MQ9 MQ 9 MQ-9 Smoke Liquefied Flammable Methane Gas Sensor Module for Arduino Diy Starter Kit
Description:
1.using high-quality dual-panel design, with power indicator and TTL signal output instructions;
2.the switching signal having a DO (TTL) output and analog output AO ;
3.TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
4.the higher the voltage of the analog output voltage with concentration higher .
5.for the carbon monoxide detector has good sensitivity.
6.there are four screw holes for easy positioning ;
7 Product dimensions : 32 (L) * 20 (W) * 22 (H)
8.has a long life and reliable stability
9.rapid response and recovery characteristics
Electrical properties:
Input voltage : DC5V Power consumption ( current ): 150mA
DO output : TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V
Special note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .
Package included:
100% Brand New
1 PCS MQ-9 Module
