Arduino Breathalyzer Using MQ3 Gas sensor and OLED Display
https://www.electronics-lab.com/arduino-breathalyzer-using-mq3-gas-sensor-oled-display/
A breathalyzer is a generalized trademarked name for devices used for determining blood alcohol content from a breath sample. This means the device can detect from your breadth, the amount of alcohol you have taken. This device becomes very useful when you consider several cases of accidents caused by drunk driving. With this device, you […]
SprintIR6S, World’s Fastest NDIR CO2 Sensor
https://www.electronics-lab.com/sprintir6s-worlds-fastest-ndir-co2-sensor/
Gas Sensing Solutions (GSS) Ltd is a designer and manufacturer of low power, high speed Non-Dispersive Infrared (NDIR) carbon dioxide gas sensors. Recently, it has claimed a new speed record for its SprintIR6S NDIR CO2 sensor. The new sensor comes with response rates that had never been reached before by any other NDIR CO2 sensors. It can […]

Pesky Products @ tindie.com writes: This is a small (17.9 mm x 10.3 mm) breakout board with Bosch’s BME280 pressure, temperature, and humidity sensor as well as AMS’ CCS811 digital gas sensor. The sensors work in concert to provide a complete measurement via I2C register reads of indoor air quality including temperature- and humidity-compensated estimates […]
ESP8266 mains energy monitor
https://www.electronics-lab.com/esp8266-mains-energy-monitor/
Brian Dorey has designed a mains energy monitor based on ESP8266 that have sensors for the mains current, electric meter and gas meter. As the new solar logger did not have this functionality we decided to design a new data-logger that would measure not only the mains current usage but also keep track of the […]
LPG Sensor Alarm
https://www.electronics-lab.com/lpg-sensor-alarm/
sameer @ sgprojects.co.in has build a LPG gas detection circuit based on LM358: LPG gas detection project’s main idea is to implement the security system for detecting leakage of liquid petroleum gas in closed environment. In this project gas leakage is identified by using MQ6 gas sensor. A simple circuit with an Op-Amp IC is […]
CCS811 – Digital CMOS gas sensors for wearables & IoT
https://www.electronics-lab.com/ccs811-digital-cmos-gas-sensors-for-wearables-iot/
by Graham Prophet @ edn-europe.com: Cambridge CMOS Sensors is a semiconductor company that designs gas sensor solutions to monitor the local environment; its CCS811 is the first digital product in its CCS800 product family of ultra-low power miniature gas sensors. The CCS811 integrates a metal oxide gas sensor with a microcontroller sub-system which enables Indoor Air […]

Stefan over at Hackster.io has written an article detailing his DIY Wi-Fi gas detector that sends SMS alerts: Hey guys, back with another little project that I’ve been fiddling with for the past week. With kids around, every parent is thinking how to make their home safer for the little ones and for everybody in […]
Get rid of unpleasant odors easily and effectively
https://www.electronics-lab.com/get-rid-of-unpleasant-odors-easily-and-effectively/
USM-MEMS-VOC module evaluates rate of air pollution by contaminants such as cigarette smoke and cooking odors and allows control of air ventilation system on demand. Modul USM-MEMS-VOC is based on the innovative and highly stable TGS 8100 MEMS semiconductor sensor TGS8100 from Figaro. In the presence of detectable gas, sensor resistance decreases depending on gas […]
Environmental Alert System
https://www.electronics-lab.com/environmental-alert-system/
by Aleator777: What’s that smell? It’s noxious gas of course! If you’re in an environment where there’s a possibility of gaseous release of which you’d rather not breathe, why not build an automatic system for sensing and alerting you? The design for the Environmental Alert System is driven by my motivation to understand the concentrations […]
