Soil Moisutre Measure not works! about vinduino

[ReiniervdL]

The Vinduino-H code is for a handheld reader, works for one sensor only. Can you describe your setup? Are you using the Vinduino handheld PCB? Does the code compile?

I try to use the Vinduino handheld PCB and i have connect only sensors. I try use your code in a samd21 board
But the measures not's works

[ReiniervdL]

I have no experience with the SAMD21 board. The operating principle is measuring a voltage in a voltage divider, where one of the resistors is the sensor, and the other resistor is your reference. You should check correct wiring first and then look at the ADC measurements. Also make sure that the Watermark sensor is wetted, a dry sensor is infinite impedance.

Hi Reinier,

Thanks for your answers. I have now different meassures but i don't understand the results Could you give me a hand?.

In WM1 i have connect a Irrometer sensor (Dry).
In WM2 and Wm3 i have nothing.

A dry watermark sensor is basically an open circuit. You may want to check your circuit first with known resistor values connected to the sensor inputs.

This values is with 22k in WM1:

WM1: 298552,2
WM1: 8670,15
WM1: 201160,2
WM1: 8706,15
WM1: 297079,2
WM1: 8409,15
WM1: 284256,2
WM1: 7925,15
WM1: 291596,2
WM1: 8521,15
WM1: 322377,2
WM1: 7823,15
WM1: 183822,2

Part of Code:

SerialUSB.print("WM1: ");
SerialUSB.print(valueOf[NUM_READS/2].resistance);
SerialUSB.print(",");
SerialUSB.print(valueOf[NUM_READS/2].moisture);
SerialUSB.println ();

Thanks so much!

[ReiniervdL]

The SerialUSB.print(valueOf[NUM_READS/2].resistance should show a value of 22k. I cannot tell you remotely why it does not work. First thing to try is program the unit to provide static state DC to the interface voltage divider. Use a volt meter to measure the voltage and compare with the ADC input reading. Best,

Hi, i fix now the board, the problem is in my pcb.

Thanks for you support!
