## Overview

The KEYESTUDIOTDS Meter Probe is a cutting-edge sensor module designed for Arduino enthusiasts, enabling precise measurement of Total Dissolved Solids (TDS) in water. With a user-friendly plug-and-play setup, it operates within a wide voltage range of 3.3 to 5.5V and provides an analog output of 0 to 2.3V. Ideal for both hydroponics and domestic water quality testing, this sensor empowers users to ensure cleaner water effortlessly.

## Description

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

## Features

- 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. How to use: Search for "keyestudio wiki KS0429" in Google Chrome to get the wiki online tutorial for this product.

## Questions & Answers

**Q: Will this work on salt (ocean) water (not continuously submerged)?**
A: Depends on the tds level of the water. This meter only goes up to 1000 ppm. If the water is higher than that it won’t read it correctly

**Q: Can this be left submerged permanently?**
A: If you talk about the sensor itself, I would say yes. Depends a bit on the salinity of the fluid you are measuring. Sea water will destroy everything given enough time. Potable water should be OK.

**Q: Can i use this sensor an esp32 board? the example code is for arduino uno**
A: Yes it works just fine with an ESP 32. the example code works as well for the esp 32

**Q: Does this come with any calibration solutions or what is recommended for calibration?**
A: it does not. Also, it only reads up to 1000ppm, so its ok for water quality testing, but not hydroponics nutrient solution.
you can buy calibration solution on amazon
