TDS Sensor with Board Module V1.0

TDS Sensor with Board Module V1.0 The TDS Sensor with Board Module V1.0 is designed to measure the total dissolved solids (TDS) in water, providing an indication of water purity. It outputs an analog voltage proportional to the TDS value, making it compatible with microcontrollers such as Arduino and ESP32. The module features a waterproof probe for submersion in water, while the signal transmitter board should remain dry. With low power consumption and adjustable sensitivity, it is suitable for various water quality monitoring applications. Features • Measures total dissolved solids (TDS) in water. • Analog voltage output (0–2.3V) proportional to TDS. • Compatible with 3.3V and 5V microcontrollers. • Waterproof probe for submersion in water. • Low power consumption (3–6mA). • Suitable for water quality monitoring and hydroponics. Specifications Parameter: Value Input Voltage: 3.3–5.5VDC Output Voltage: 0–2.3VDC Working Current: 3–6mA TDS Measurement Range: 0–1000ppm TDS Measurement Accuracy: ±10% F.S. (25°C) Module Dimensions: 42mm x 32mm Module Interface: PH2.0-3P Electrode Interface: XH2.54-2P Probe Length: 60cm Probe Needles: 2 Probe Color: White PINOUT Num | Label | Description 1 | – | Power GND(0V) 2 | + | Power VCC(3.3 ~ 5.5V) 3 | A | Analog Signal Output(0 ~ 2.3V) 4 | TDS | TDS Probe Connector 5 | LED | Power Indicator Applications • Drinking Water Quality Monitoring. • Aquariums and Fish Tanks. • Hydroponics and Agriculture. • Swimming Pools and Spas. • Industrial Water Treatment. • Environmental Water Testing. • Beverage and Food Industry. • Medical and Laboratory Applications. • Boiler and Cooling Tower Maintenance. Attention • The probe can not be used in water above 55 degrees centigrade. • The probe can not be left too close to the edge of the container, otherwise it will affect the reading. • The head and the cable of the probe are waterproof, but the connector and the signal transmitter board are not waterproof.
