Just a note on turbidity, this probe is a 180 degree one or absorption turbidity units, where the standard method is in 90 degrees, o light scattering by particles minimizing the size of the particle effect. In the other hand this probe is an IR based one hence insensitive to water color, where color maybe not be a turbidity correlated parameter so a colored water may have low turbidity where a “white” water may have very high turbidity. Just to know if you want to use this in drinkable water as your water company does. (Yo may need complex calibration). Conclusion this probe may be great for trending but maybe not very good for actual values.
can we change the mode over arduino code. Example: i choose the face recognition then i want to change over an arduino code into the object recognition, is it possible ?
How can you have white LED when there is no such thing as white light? Do you know if lasers are at all involved in QR code scanners? I am concerned about the bright red light shining in my eyes from inappropriately placed QR code scanners with bright red lights. I would NEVER place them like that like shining straight into the customers' eyes but I am a customer and the employees place them facing straight into our eyes instead of pointing them downwards.
What input voltage are you using? All the ones I have used have stated 9-12V input and the receiver side powers at 5V2Amp. Every time I load the transmitter side with either bench power or a DC adapter the chip over heats and blows.
