TDS Water Quality Module | Analog Level Sensor for Arduino

This TDS sensor module lets you measure Total Dissolved Solids in water. You can use it with an Arduino. It checks the water's electrical conductivity. This relates to the amount of salts, minerals, and metals present. The kit has the V1.0 amplifier board and a waterproof probe. Features and Benefits - Analog Voltage Output - The board changes the probe's reading into an analog voltage (0-2.3V). A microcontroller's analog pin can easily read this. - Waterproof Probe - The two-pin TDS probe for water testing is fully submersible. You can put it directly in a tank, glass, or water stream. - 3.3V and 5V Compatible - This TDS sensor module works with 5V systems like the Arduino Uno. It also works with 3.3V systems like the ESP32. This offers good project flexibility. - Simple 3-Pin Connection - Connecting the module is easy. Just give it power (VCC), ground (GND), and connect the analog signal pin to your Arduino. Applications - Water Filter Monitoring - Test your tap water. Compare it to filtered water to see how well your purifier works. Purified water is often under 50 PPM. - Hydroponics Nutrient Levels - Use it as a water conductivity sensor in your hydroponics setup. It tracks the amount of nutrients in the solution. - Aquarium Water Hardness - Build an Arduino water quality monitor. It checks the purity of your freshwater aquarium. This helps you keep a stable environment. Key Functions This Water Quality & Flow Sensor module is designed for water quality monitoring. It measures purity in parts per million (ppm) within a range of 0-1000 ppm. The sensor provides an analog output signal, making it compatible with Arduino systems. Its primary function is to detect and report water quality data, allowing for consistent monitoring in various applications. This TDS sensor module is a current sensor type, built from metal for durability. Common Types of Flow Meters A flow meter is a device used to measure the rate of fluid flow. While this specific product is a water quality and flow sensor, understanding general flow meter types can be beneficial. Common types include differential pressure, velocity, positive displacement, and mass flow meters. Each type operates on different principles to quantify the movement of liquids or gases. The choice of flow meter depends on the application's specific requirements, such as fluid type, accuracy needed, and operating conditions. Key Types & How They Work Flow meters work by sensing the movement of a fluid and converting that movement into a measurable signal. For instance, some meters use the principle of differential pressure, where a restriction in the flow path creates a pressure drop, which is then measured. Others, like velocity-based meters, measure the speed of the fluid. This Water Quality & Flow Sensor specifically monitors water purity, operating as a current sensor to provide an analog output signal compatible with Arduino for data interpretation. Velocity-Based Meters Velocity-based meters determine flow by measuring the speed at which a fluid travels through a pipe. This speed is then used to calculate the volumetric flow rate. Examples include turbine meters, electromagnetic meters, and ultrasonic meters. These devices are often chosen for their accuracy and ability to handle a wide range of flow rates. While this product is a water quality and flow sensor, understanding velocity-based flow measurement provides context for different fluid monitoring technologies. Differential Pressure (DP) Meters Differential pressure (DP) meters operate by introducing a constriction into the flow path, which causes a pressure drop. This pressure difference is proportional to the square of the flow rate. Common DP devices include orifice plates, venturi tubes, and flow nozzles. These meters are widely used due to their robustness and suitability for various industrial applications. This Water Quality & Flow Sensor, however, is a TDS sensor module designed for water quality monitoring, providing a 0-1000 ppm measurement range with an analog output.
