Some feedback will be nice to have on all these resuqest for aswers on the Forum, for other people reference, one of the best way to increase the Forum base knowledge.

Happy breadboarding!!

- Thu Mar 24, 2016 2:06 pm #43963 I would like to know also since I have the same problem..

I put a 3.3 to 5Volt converter between my ESP and the sensor and on the other side I used a little voltage divider.
I used a LOW signal to drive the sensor-led but whatever I do the output is to low to make sense. (around 200mV - the sensorspecs say it works past 500mV)

the strange thing is that by varying the timing (specs say:280usec on;sample;40usec on;9600 usec off) the voltage works opposite of what I would think should happen..
Looking at the output-diagram of the sensor changing the timing to 200;120;9600 should probably give a lower output-Voltage but in my case it goes from 160mV to 200mV (measured by the ADC from the ESP)

Measurementvalues do go up when I blow some smoke from my solder-iron into the sensor so it is not dead.

I don't have an osciloscope to see what is going on.

Has anyone got it running??
