Description of Arduino-Compatible TDS Meter Probe for Water Quality Monitoring V1 Sensor Module with XH2.54-3Pin Jumper Wire Connector by KEYESTUDIO

This TDS probe sensor for arduino is used to measure TDS value of the water. The TDS value can be used as one of the basis for reflecting the cleanliness of water. TDS (Total Dissolved Solids): indicates how many milligrams of soluble solids dissolved in one liter of water. The higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. This TDS Meter Probe is plug and play and easy to use. Also, the wide supply voltage of 3.3~5.5V and the analog signal output of 0~2.3V. Comes with XH2.54-2P/3P connector wires. Its Electrode can measure conductive materials, such as suspended solids, heavy metals and conductive ions in water. Also, it can be used for water quality testing in the field of domestic water and hydroponics. With this sensor, you can easily DIY a TDS detector, and easily check the cleanliness of the water to make your water quality better.

Just what I needed

I bought this and a haze sensor to add to my K40 laser cutter setup. This item turned out perfect. My problem is that it's cooled by water in a bucket in a place I can't see, so it's hard to tell if there's algae in the water etc. This sensor gives me instant readings. I just used the sample code from the wiki and was ready to race.

Pros
  • Computers & Accessories
Cons
  • crumpled

Inaccurate and low PPM value

You are really inaccurate. I compare it to TDS readings from a portable device and this meter consistently reads twice as much as the meter reads. If the meter registers a 1024 at less than 500ppm it can't be used for even the simplest greens in a hydroponic system so I just spent hundreds on a real Atlas Scientific meter and I'm hoping it works better. Maybe they can say that hydroponics is not the intended goal, but they still have to be accurate within the intended range and there is no way…

  • This Arduino TDS sensor is used to measure the TDS value of water. The TDS value can be used as one of the bases to reflect the purity of the water.
Cons
  • Requires socket

Inaccurate and low PPM

They are really inaccurate. I compare it to TDS readings from a portable device and this meter consistently reads twice as much as the meter reads. If the 1024 gauge registers below 500ppm it can't even be used on the simplest leafy greens in a hydroponic system so I've just spent hundreds on a real Atlas Scientific gauge and am hoping it works better. Maybe they can say that hydroponics is not the intended goal, but they still have to be accurate within the intended range and there is no way…

Pros
  • With this sensor you can easily make a DIY TDS detector and check the purity of the water to improve its quality. How to use: Type "keyestudio wiki KS0429" in Google Chrome to get the online manual for this product.
Cons
  • Slightly torn

Works but requires a lot of adjustment

I bought two of these to measure the TDS of the water entering my reverse osmosis system and the levels leaving it. That way I know when to change the filters instead of blindly doing it every x months. The data is saved in the Home Assistant and I get a push notification if I need to replace it now. First, I connected these sensors to an analog-to-digital converter (ADC) on an ESP32 microcontroller and tested it in both the Arduino IDE and ESPHome. . Tension was everywhere, generating garage…

Pros
  • TDS (Total Dissolved Solids): Shows how many milligrams of soluble solids are dissolved in one liter of water. The higher the TDS value, the more soluble solids are dissolved in the water and the less pure the water is.
Cons
  • Fading
