It works by passing a small electrical current between two electrodes submerged in the water and measuring the conductivity — higher dissolved solids result in greater conductivity. This module outputs an analog signal that a microcontroller (such as Arduino) reads and converts to a ppm value.\u003c\/p\u003e\n\u003ch4\u003eQ: What platforms is the TDS Meter V1.0 Sensor Module compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: The TDS Meter V1.0 Sensor Module operates on a supply voltage of 3.3V–5.5V, making it compatible with a wide range of popular platforms including Arduino Uno, Arduino Nano, Raspberry Pi (with an ADC), ESP8266, ESP32, and other common microcontroller boards. Simply connect VCC, GND, and the analog output pin to your platform to get started.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the measurement range of this TDS sensor, and is it suitable for drinking water testing?\u003c\/h4\u003e\n\u003cp\u003eA: This module has a measurement range of 0–1000ppm, which covers the typical range for tap water (50–300ppm), purified water (\u0026lt;50ppm), and moderately mineralized water. It is well-suited for DIY water quality monitoring, hydroponics, aquariums, and science projects. For certified regulatory or clinical water testing, a professionally calibrated instrument is recommended.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this TDS sensor module outdoors or in harsh conditions?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — the module supports an operating temperature range of -40°C to +85°C, making it suitable for a wide variety of environments, including outdoor monitoring stations and industrial prototypes. Ensure the electronics (PCB) are protected from direct water exposure; only the sensing probe\/electrodes should contact the liquid being measured.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
