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.
