6️⃣ How to Use

Hardware Setup

Start by gathering your Arduino board, the Gravity Analog TDS Sensor Meter, jumper wires, and the liquid you want to test. Connect the sensor to your Arduino board: wire the "GND" pin to ground, the "+" pin to 5V, and the "A" pin to analog input A1 (or any available analog pin).

Software Installation

Download and install the Arduino IDE from the official website. Copy the sample code provided by DF Robot into a new sketch. If you plan to calibrate the sensor, also download and install the GravityTDS library.

Uploading Code

Connect your Arduino board to your computer using the USB cable. Select the correct board type and port in the Arduino IDE. Click the upload button to transfer the code to your board. Open the serial monitor to view the TDS readings.

Calibration (Optional)

For accurate readings, calibrate your sensor. Prepare a known TDS buffer solution (707ppm recommended) or measure a liquid with a reliable TDS pen. Type "enter" in the serial monitor to enter calibration mode. Then type "cal:707" (or the known value) and "exit" to save the calibration.

Taking Measurements

Place the TDS probe in the water sample, ensuring the tip is fully submerged. Wait for the readings to stabilize in the serial monitor. Record the TDS value in parts per million (ppm). Clean and dry the probe between measurements.

Safety Tips

Never use the probe in water above 55°C. Keep the sensor board and connector away from water—only the probe head and cable are waterproof. Do not place the probe too close to the container wall for accurate readings. Handle the sensor board carefully to avoid moisture damage.

Maintenance

Clean the probe thoroughly after each use with distilled water. Store the sensor in a dry, safe place. Periodically check and recalibrate the sensor to maintain accuracy. Replace the probe if readings become unreliable.
