Complete Training: MQ-2 Sensor — Gas Detection, Measurement and Integration on Microcontroller
Learning objectives
- Understand the operation of the MQ-2 sensor for detecting combustible gases and smoke
- Acquire the basics of sensor electronics (power supply, connections, signals)
- Discover practical applications and limitations of the MQ-2 (safety, home automation, environment)
- Build detection setups and measure the main gases detectable by the MQ-2
- Analyze sensor data with a microcontroller (Arduino or equivalent)
- Implement alerts via LED, buzzer, or connected notification
- Calibrate and interpret the MQ-2 sensor output values
The Learni story
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1Discovery of Gas Sensors and Presentation of the MQ-2
1. Introduction to different types of gas sensors (technologies, uses) 2. Detailed view of the MQ-2: operating principle, specifications, detected gases (LPG, propane, methane, smoke, etc.) 3. MQ-2 module electronics: pinout, internal circuit operation, usage conditions 4. Practice: simple mounting on breadboard, power supply, reading output voltage
Module 2Measuring, Calibrating and Integrating the MQ-2 Sensor
1. Measurement methodology with the MQ-2: preheat time, sensitivities, false alarms 2. Sensor calibration: potentiometer adjustment, calibration with controlled gas sources (lighter, alcohol, smoke) 3. MQ-2 limitations: cross-sensitivity, error factors, sensor lifespan 4. Practice: recording measurements with multimeter and data acquisition using an Arduino board
Module 3Exploitation with Microcontroller and Advanced Applications
1. Reading analog/digital signal via Arduino: wiring diagram, sample sketch (Arduino IDE) 2. Software processing: alert thresholds, noise filtering, serial monitor display 3. Implementation of alert systems (LED, buzzer, possible WiFi notification) 4. Real-world application examples: connected smoke detector, environmental monitoring, home security 5. Project practice: building a mini gas/smoke detection project with alert

At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.
Equipment required
For the smooth delivery of the Complete Training: MQ-2 Sensor — Gas Detection, Measurement and Integration on Microcontroller program, the following equipment is required:
- Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
- Training environments installed on workstations or accessible online
- Course materials, hands-on exercises and complementary resources
- Post-training access to materials and educational resources
For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.
* contact us for remote delivery feasibility** ratio varies depending on the program
Skills assessment methods
Assessment of skills acquired during the Complete Training: MQ-2 Sensor — Gas Detection, Measurement and Integration on Microcontroller program is performed through:
- During training: case studies, hands-on labs and professional scenarios
- End of training: self-assessment questionnaire and skills evaluation by the trainer
- After training: completion certificate detailing acquired skills
Program accessibility
Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.
Enrollment terms and lead times
Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.
Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
