TF-TDS Sensor

The sensor is a cominbation of temperature sensor, flow speed sensor and water quality TDS sensor.

• Temperature sensor, direclty to arduino A0 to read, already have pull up resistor on board
• flow speed

TDS Measurement

• it can measure two seperated channels of TDS, the main connector only detect one channel
• Another XH2.54mm socket can attach another channel

• baudrate 9600, ready hex bytes
• Example output value @2 0088 0000 00 -> 0088 means TDS value 88 ppm on first channel

Demo video

• Test with pure water, and keep adding little coffee into it
