Sell ✩Analog Alcohol Sensor MQ3☉ best price

This MQ3 gas sensor is sensitive to different gasses but is most sensitive to alcohol with a detecting concentration from 0.04mg/L to 4mg/L. This module is compatible with the 5v power supply. It has 4 pins (Digital Pin, Analog Pin, VCC, GND), but needs three (either D or A) to interface this to your Arduino. You may integrate this module with different projects that have alcohol presence monitoring in it. Or a breathalyzer to check if a person is intoxicated with alcohol. MQ3 Alcohol Gas Sensor Module is used for detecting alcohol concentration on your breath, like a Breathalyzer. This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the alcohol concentration. Note: PCB dimension, and color may vary slightly. Note: Power off circuit before connecting/disconnecting the sensor Specifications Concentration : 0.05 mg/L ~ 10 mg/L Alcohol Operating Voltage : 5V ±0.1 Current Consumption : 150mA Operation Temperature : -10°C ~ 70°C Pin Out VCC – Input Power Supply GND – Supply Ground DO – Digital Output AO – Analog Output 🍀Thank you for seeing our products.
