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
