    • Great value.

      This sensor arrived in a sealed anti-static bag (always a bonus). I had it working within minutes. I have an Uno and a Mega and this sensor works on both. The connections are easy, just connect +5V or VIN, ground and analog out (A0 on both Uno or Mega). Digital out is available but I don't particularly need to use it. I can program an alarm level within the Arduino IDE etc. using the analog data. Once everything is hooked up, just use the "pinMode(A0,INPUT);" and "int sens=analogRead(A0);" commands in the appropriate areas of the code and you are up and running. Obviously you need to decide what to output to (serial print or TFT etc). With some digging around the internet, you can find help converting the "raw" analog data into PPM etc. (that's half the fun right?)
