Don’t forget to share the tutorial with ...
20160505· The MQ2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and it returns 0 with 0V. Any voltage in …
This project is to integrate 3 sensors that detect different kinds of gases and particles with Nodemcu and then, send the data detected to the internet. The 3 sensors are MQ2 sensor for smoke, MQ9 sensor for carbon monoxide and PMS3003 G3 particle sensor for , and PM10. Nodemcu ESP8266 is a very good micocontroller for developing IoT project because it has an inbuilt WiFi ...
