Buen sensor!
Muy buen sensor, me agradaría que ademas del código de arduino que proporcionan para su funcionamiento, agregaran el código para pic.

Max 500PPM at 3.3V
If you are using a device like the raspberry pi PICO with 3.3V, the max you can get is a 500ppm. I've measured the voltage being returned from 0-500 and I could only get to 500 before the voltage never went up anymore. I'm guessing thats why 5v may give you 1000ppm, but can't be sure.

Decent sensor great price
I am using this with an esp8266. Things to note you will need to calibrate this and do a 2 point calibration one at 1000ppm one at 500 or the range you expect to hang out in for measurement. Do not calibrate 0 ppm at 0 volts if using this any microcontroller based ADC unless you plan on using a coupling cap and build an isolation circuit for it. 12 bit adc's are often noisy even with a stable reference voltage if you calibrate 0ppm at 0 volts it will skew the entire scale linearly. Instead use a lower but not 0 range like 50 ppm. This will save your reading from noise. and you will probably still be able to read zero. It took me a day to come to that and it has been working great I calibrated at 300 840 and 1000. 840 is where I am normally at in my nutrient tank.

Product as expected
The project this was purchased for has been postponed. I am sure it will work as expected.

tout fonctionne comme prévu.
J’ai préparé un programme Arduino avant de recevoir la pièce quand je l’ai reçu je l’ai simplement branché et tout fonctionne parfaitement bien.

Works great
Everything works fine, works with both 3.3v and 5v, appears to operate in AC so probes will never corrode.

DOA
Appears to have a faulty drive op-amp, the voltage at the probe is biased heavily to the negative side. No output on yellow lead. Sent it back. I didn't expect a device this simple to be DOA but you never know anymore.

Parts did not fit together
The power/signal cable connector wouldn’t plug into the board. The board came with a different style connector as shown in the picture.
