Moisture Sensor

[treb0r]

Hi
I have built Moisture Sensor according this project: http://www.mysensors.org/build/moisture
I used analog pin and changed values into % value which is visible correctly in domoticz. The problem is when I want to use this value in blocky event creator.
In current values I have only 0, 1, 2, or 3 values which probably indicate dry, wet etc. I don't have access to % value during building the rule. Even when I take 0, 1, 2, or 3 values, they don't work and I can't build any events basing on them. Does anybody know why?

that is because this is not implemented in the event system, someone has to add support for percentage checking

[treb0r]

What about light_level? So how should I present my sensors (and with which values) in the node to make them useful in domoticz building the events?

I've build this sensor with the (red) water level sensor. But how can I implement this into domo ?
When I add this on the hardware tab it thinks its a switch, and after that I can change this switch. But the moisture (sensor) is not available.
How to do this ?

Well it is a switch !

So it seems to be doing what it should do

take a look in your sketch, a switch (tripped) command is send when there is (or is not) soil water

OK but I use this one :

So it must tell me the % , so I know if I must fill the water in the aquarium

If you use the standard sketch from MySensors it is as Gizmocuz said, sending on/1 (moist) or off/0 (dry). You need to recode it in your sketch if you want it in % and then maybe you could present it as a humidity sensor (becuse humidity shows in %).

Or you have to set a minimun of water that is ok in your aquarium, and then send the 0 when that is reached. When a 0 enters in domoticz you can start filling your aquarium with water.

Okay thanks ! Will try this .
At the moment the switch doesn't do anything

It doesn't work the way i want.
When i start googling the normal arduino code :
void setup(){

 

Serial.begin(9600);

 

}

 

void loop(){

 

Serial.print("Water level Sensor Value:");

Serial.println(analogRead(A5));

delay(100);

 

}





But how tot implement this to mysensors ?

Code: Select all

#include <SPI.h>
#include <MySensor.h>  

#define DIGITAL_INPUT_SOIL_SENSOR 3   // Digital input did you attach your soil sensor.  
#define INTERRUPT DIGITAL_INPUT_SOIL_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
#define CHILD_ID 0   // Id of the sensor child

MySensor gw;
MyMessage msg(CHILD_ID, V_TRIPPED);
int lastSoilValue = -1;

void setup()  
{ 
  gw.begin();

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Soil Moisture Sensor", "1.0");
  // sets the soil sensor digital pin as input
  pinMode(DIGITAL_INPUT_SOIL_SENSOR, INPUT);      
  // Register all sensors to gw (they will be created as child devices)  
  gw.present(CHILD_ID, S_MOTION);
}
 
void loop()     
{     
  // Read digital soil value
  int soilValue = digitalRead(DIGITAL_INPUT_SOIL_SENSOR); // 1 = Not triggered, 0 = In soil with water 
  if (soilValue != lastSoilValue) {
    Serial.println(soilValue);
    gw.send(msg.set(soilValue==0?1:0));  // Send the inverse to gw as tripped should be when no water in soil
    lastSoilValue = soilValue;
  }
  // Power down the radio and arduino until digital input changes.
  gw.sleep(INTERRUPT,CHANGE);
}

you have correct code on top of this topic. Change pin number to pin where you plugged device
