### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Plug and play
  

*by C***E on Reviewed in the United Kingdom on 30 September 2023*

Only used the analogue output but output to arduino and read the value.Simple 5v supply but seem to work ok on 3.3v tooCalibration is still a work in progress

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Tolerance between devices too great
  

*by I***N on Reviewed in the United Kingdom on 13 September 2024*

After testing and leaving these devices to 'settle down', the readings between the devices whilst located next to each other vary so much that I just can't rely on them, they also fluctuate quite a bit which was a surprise too.I've literally got two of these side by side and one is nearly (!) double the value (analogue) to the other (swapped ports to confirm it wasn't my MCU).I can calibrate these which I may do (or get a different supplier in the hope they are more aligned), but not a great initial impression. I did test with some chemicals nearby and they did react very quickly, hence the 3 stars.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works

Can print pretty graphs using this sensor as an input.
