Descripción
💧 Stay ahead of contamination—monitor water quality like a pro!
- DEDICATED SUPPORT - Backed by expert customer service to keep your water quality monitoring seamless and stress-free.
- LONG TERM STABILITY - AC excitation source extends probe life and ensures consistent, reliable measurements over time.
- PLUG PLAY PRECISION - Effortlessly integrate with Arduino and similar 3.3V/5V systems for instant water quality insights.
- VERSATILE APPLICATION - Ideal for domestic water, hydroponics, labs, and online monitoring—your all-in-one water quality sentinel.
- REAL TIME CLEANLINESS METRICS - Measures dissolved solids in mg/L, giving you actionable data on water purity at a glance.
This Arduino-compatible analog sensor module measures total dissolved solids (TDS) in water, providing real-time, accurate water cleanliness data via a 0~2.3V output. Operating on a wide 3.3~5.5V range with AC excitation to prevent probe polarization, it ensures long-term stability and durability. Perfect for scientific research, hydroponics, domestic water testing, and continuous online monitoring.

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.
