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
