Giới thiệu [1 CÁI] Module Cảm biến Khí gas Metan MQ-4 MQ4

Module Cảm biến Khí gas Metan MQ-4

Mô tả sản phẩm:
MQ-4 Gas Sensor Module Methane Gas Detective Sensor
Methane Gas Detective Sensor MQ-4 Gas Sensor Module
MQ-4 Gas Sensor Module Methane Gas Detective Sensor MQ-4
Module Applications:
Suitable for home or factory methane gas , natural gas and other monitoring devices to test natural gas, methane 300 to 10000ppm;

Thông số kỹ thuật:
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 , the concentration of the analog output voltage is higher.
5. For methane, natural gas has a good detection sensitivity.
6. There are four screw holes for easy positioning ;
7. Dimensions : 32 (L) * 20 (W) * 22 (H)
8. 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 power on, it needs to be warmed up around 20S, measured data can be stable , sensor become warm is a normal phenomenon.
The instruction of Wiring:
1. VCC: positive power supply (5V)
2. GND: power supply is negative
3. DO: TTL switching signal output
