MQ-4 Natural Gas Sensor ( Methane-CH4)
৳ 155.00 ৳ 140.00
This semiconductor gas sensor detects the presence of methane (CNG) gas at concentrations from 300 ppm to 10,000 ppm, a range suitable for detecting gas leaks. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller
General Specifications:
1. Analog output voltage with concentration, the higher concentration, the higher voltage.
2. Has long service life and reliable stability
3. Rapid response recovery features
Specification:
Input voltage: DC5V
Power consumption (current) : 150 mA
AO output: 0.1-0.3 V (pollution-free)
The highest concentration of voltage: Approx 4 V
The detection range of alcohol: detection range of 10 ~ 1000 PPM
Connection mode:
1. VCC: Positive (5 v)
2. GND: Connect power negative
3. DO: TTL switch signal output
4. AO: Analog signal output
Package Include:
- 1 x MQ-4 Methane CNG Gas Sensor
MQ-2 Flammable Gas & Smoke Sensor
