<p><b>New page</b></p><div>The sensor is a cominbation of temperature sensor, flow speed sensor and water quality TDS sensor.<br />
<br />
* Temperature sensor, direclty to arduino A0 to read, already have pull up resistor on board<br />
* flow speed <br />
<br />
== TDS Measurement ==<br />
* it can measure two seperated channels of TDS, the main connector only detect one channel<br />
* Another XH2.54mm socket can attach another channel<br />
<br />
* baudrate 9600, ready hex bytes<br />
* Example output value @2 0088 0000 00 -> 0088 means TDS value 88 ppm on first channel<br />
<br />
== Demo video ==<br />
* Test with pure water, and keep adding little coffee into it<br />
