Guide for MQ2 Gas Sensor with Arduino | Random Nerd Tutorials


May 05, 2016· 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 ...

Arduino CNC Shield – GRBL Compatable |


Aug 30, 2015· Hi, I do have a question just to be sure. I have a cheap CO2 laser using a controllerboard called Moshi. That Moshi board only communicates with software I do not want to use 😉. On the internet I find a lot of ‘hacks’ that replace the Moshi board by Arduino with Ramps. I do have a few Ramps on stock and a few CNC v3 shields.

Measure Soil Nutrient using Arduino Soil NPK Sensor


Nov 21, 2020· Similarly, we have to enable DE RE high. To do this connect the DE RE Pins to the D7 D8 pin of Arduino. The NPK Sensor has 4 wires. The brown one is VCC which needs a 9V24V Power Supply. The GND pin which is black in color. So connect it to the GND of Arduino.
