MQ-3 Alcohol Sensor
Original price was: ₹199.00.₹169.00Current price is: ₹169.00.
The MQ3 gas sensor is alcohol sensor which is used to detect the alcohol concentration on your breath. This sensor provides an analog resistive output based on alcohol concentration.
This MQ-3 Gas Sensor is suitable for detecting alcohol concentration in your breath, just like your common breathalyzer. The MQ-3 Gas Sensor provides an analogue resistive output based on alcohol concentration. When the MQ-3 Gas Sensor is present in the environment in which the alcohol vapour, the sensor’s conductivity increases with the concentration of alcohol gas in the air increases. Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal.
Specifications:
- Input voltage: DC5V
- Power consumption (current) : 150 mA
- DO output: TTL digital 1 and 0 (0.1 and 5 V)
- AO output: 0.1-0.3 V (pollution-free)
- The highest concentration of voltage: Approx 4 V
- Detection range of alcohol: detection range of 10 ~ 1000 PPM
Features:
- High-quality double panel design, with power indicator and TTL output signal
- Have DO switch signal(TTL) output and AO analogue signal output
- TTL output signal for low level effectively. (when the low output electric signal lights at ordinary times, can be directly connected to a single-chip microcomputer or relay module)
- Analogue output voltage with concentration, the higher the concentration, the higher voltage
- MQ-3 Gas Sensor has better sensitivity to liquefied petroleum gas, natural gas, city gas, smoke
- MQ-3 Gas Sensor has long service life and reliable stability
- Rapid response recovery features
