Web6 jun. 2024 · Interfacing MQ-3 Alcohol Sensor with Raspberry Pi 3. Since MQ-3 sensor provides analog output, we have got MCP 3008. We tried to make the connections with Raspberry pi 3 using the connections from MQ-2 sensor available online. Nothing works! Need help to interface MQ 3 with Raspberry pi 3 for detecting Alcohol Level. WebMQ3 Sensor belongs to the MQ series that are used to detects different gasses present in the air. This alcohol sensor detects the concentration of alcohol 25 to 500 ppm in the air. Along with high sensitivity to detect …
WebI am new to Arduino and electronics in general.I am working on MQ 7 Gas sensor to test Carbon monoxide level. But the issue is i still can't grasp the concept of converting analog readings to PPM. I tried to follow this,but some parts, are very clear especially R0 = RS_air/(26+(1/3)) Web13 mrt. 2024 · The equipment we use today to make alcohol detectors are Arduino, LEDs, Buzzer, and MQ3 alcohol sensors. There are many MQ-X sensors available in the market for different uses, but we are going to use MQ-3 sensor. Here as it is the best to detect alcohol. However, most MQ sensors work the same.
