thanks you very much work great !

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

#define ANALOG_INPUT_SOIL_SENSOR A0
#define CHILD_ID 0 // Id of the sensor child

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

void setup()
{
gw.begin();

// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Soil Moisture Sensor - analog", "1.0");
// sets the soil sensor analog pin as input
pinMode(ANALOG_INPUT_SOIL_SENSOR, INPUT);
// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID, S_HUM);
}

void loop()
{
// Read analog soil value
int soilValue = analogRead(ANALOG_INPUT_SOIL_SENSOR);

if (soilValue != lastSoilValue) {
Serial.println(soilValue);
gw.send(msg.set(map(soilValue, 100, 250, 0, 100)));
lastSoilValue = soilValue;
}
// Power down the radio and arduino until analog input changes.
gw.sleep(1000);
}

is the same sketch but i have changed only

gw.send(msg.set(static_cast<int>(static_cast<float>(1023 - soilValue))/1023*100)); // Send the relative moisture. this will probably work only on nano or uno as I used 1023

by this

gw.send(msg.set(map(soilValue, 100, 250, 0, 100)));

i don't understand why is alway inverted ??

gw.send(msg.set(map(soilValue, 100, 250, 0, 100)));```

you have forget one ) at last .

sensor started, id 2

250 is when is in water and 1023 is dry , it's alway inverted , i can test 2 other exemple because there is a problem in sketch maybe ;or ) when is try this

gw.send((max(min(map(soilValue, 100,250,0,100), 100), 0)));

and for other 2 exemple i can send to arduino compiling error

sketch_may24a.ino: In function 'void loop()':
sketch_may24a:31: error: no matching function for call to 'MySensor::send(long int)'
C:\Program Files (x86)\Arduino\libraries\MySensors/MySensor.h:142: note: candidates are: bool MySensor::send(MyMessage&, bool)

hello

it's working but is not inverted :+1:

1023
send: 2-2-0-0 s=0,c=1,t=1,pt=4,l=4,st=ok:100

100 is when is dry and 220/250 is when the sensor is in water .
i just need little more help for invert value , 100 = in water and 0 when is dry

thx

thanks you ,

i have try your sketch but don't work send only O

send: 2-2-0-0 s=0,c=1,t=1,pt=2,l=2,st=ok:0
444
send: 2-2-0-0 s=0,c=1,t=1,pt=2,l=2,st=ok:0
470
send: 2-2-0-0 s=0,c=1,t=1,pt=2,l=2,st=ok:0
1023
send: 2-2-0-0 s=0,c=1,t=1,pt=2,l=2,st=ok:0

i think the problem is inside converter in percentage ....

240 when is in water and 1023 when completly dry .

Managed to make it a humidity sensor, which is probably close enough. Here is my sketch:
#include <SPI.h>
#include <MySensor.h>

#define ANALOG_INPUT_SOIL_SENSOR A0
#define CHILD_ID 0 // Id of the sensor child

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

void setup()
{
gw.begin();

// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Soil Moisture Sensor - analog", "1.0");
// sets the soil sensor analog pin as input
pinMode(ANALOG_INPUT_SOIL_SENSOR, INPUT);
// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID, S_HUM);
}

void loop()
{
// Read analog soil value
int soilValue = analogRead(ANALOG_INPUT_SOIL_SENSOR);

if (soilValue != lastSoilValue) {
Serial.println(soilValue);
gw.send(msg.set(static_cast<int>(static_cast<float>(1023 - soilValue))/1023*100)); // Send the relative moisture. this will probably work only on nano or uno as I used 1023
lastSoilValue = soilValue;
}
// Power down the radio and arduino until analog input changes.
gw.sleep(1000);
}

hello ,

i want to do same , but can you explaind the calcul is made ?

for now i use light sensor sketch with analog input , but i ant to modify by /10 for having a moisture meter reading value 0to100% or maybe there is a S_Percentage come in next version of mysensors ?

i use domotiz with gateway and for now only Light sensor work for read analog value .

thanks

thanks you for help , i will try and if is work i will share the code , is not very difficult but for me it is , is use a unix command since 2 week hahahah

hello everybody ,

i wan to plug 4 sensor level , is for water level of rain water tank .

i have found this code for distance sensor :+1:

#include <SPI.h>
#include <MySensor.h>
#include <NewPing.h>
 
#define CHILD_ID 1
#define TRIGGER_PIN  6  // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define ECHO_PIN     5  // Arduino pin tied to echo pin on the ultrasonic sensor.
#define MAX_DISTANCE 300 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.
unsigned long SLEEP_TIME = 5000; // Sleep time between reads (in milliseconds)
 
MySensor gw;
NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.
MyMessage msg(CHILD_ID, V_DISTANCE);
int lastDist;
boolean metric = true; 
 
void setup()
{
  gw.begin();
 
  gw.sendSketchInfo("Distance Sensor", "1.0");
 
  gw.present(CHILD_ID, S_DISTANCE);
  boolean metric = gw.getConfig().isMetric;
}
 
void loop()
{
  int dist = metric?sonar.ping_cm():sonar.ping_in();
 
  if (dist != lastDist) {
      gw.send(msg.set(dist));
      lastDist = dist;
  }
 
  gw.sleep(SLEEP_TIME);

So for 4 sensor i need to definite more like this

#define CHILD_ID1 1
#define TRIGGER_PIN1 6
#define ECHO_PIN1 8
#define MAX_DISTANCE1 300

#define CHILD_ID2 2
#define TRIGGER_PIN2 5
#define ECHO_PIN2 9
#define MAX_DISTANCE2 300

and i need change this gw.present(CHILD_ID, S_DISTANCE); by gw.present(CHILD_ID, S_DISTANCE1, S_DISTANCE2, XXXX);

so i need change other thing inside ?

thanks you

hello everybody ,

i have domoticz interfaced with mysensors , i'm very happy but i need to use SSR like thiss : http://www.dx.com/fr/p/ssr-25da-25a-solid-state-relay-white-134494#.VTuG0iHtmko .

but i have no signal , juste to power with 3,3v the side DC of m ssr ...

thanks in advance .
