## Overview

The HiLetgo TDS Sensor Kit offers a professional-grade solution for monitoring water purity with a wide voltage input (3.3-5.5V) and analog output (0-2.3V), compatible with popular Arduino controllers. Featuring AC excitation to prevent probe polarization, it delivers stable, accurate TDS measurements (0-1000ppm) with ±10% accuracy, making it perfect for domestic water and hydroponic applications. Its waterproof probe ensures reliable long-term use, empowering you to DIY your own water quality detector and protect your health.

## Description

Specifications: Input Voltage: 3.3 ~ 5.5V Output Voltage: 0 ~ 2.3V Working Current: 3 ~ 6mA TDS Measurement Range: 0 ~ 1000ppm TDS Measurement Accuracy: ± 10% F.S. (25 ℃) Module Size: 42 * 32mm Module Interface: PH2.0-3P Electrode Interface: XH2.54-2P Description: This is a TDS sensor/Meter Kit for measuring TDS value of the water, to reflect the cleanliness of the water. It can be applied to domestic water, hydroponic and other fields of water quality testing. You may also check Liquid Sensor Selection Guide to get better familar with our liquid sensor series. TDS (Total Dissolved Solids) indicates that how many milligrams of soluble solids dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water. This product supports 3.3-5.5V wide voltage input, and 0-2.3V analog voltage output, which makes it compatible with 5V or 3.3V control system or board. The excitation source is AC signal, which can effectively prevent the probe from polarization and prolong the life of the probe, meanwhile, increase the stability of the output signal. The TDS probe is waterproof, it can be immersed in water for long time measurement. Attention: 1.The probe can not be used in water above 55 degrees centigrade. 2.The probe can not be left too close to the edge of the container, otherwise it will affect the reading. 3.The head and the cable of the probe are waterproof, but the connector and the signal transmitter board are not waterproof. Please be careful. Package included: 1 x Analog TDS Sensor Meter 1 x TDS Probe 1 x PH2.0-3P Wire
