@boozz said in Ocr for Arduino or raspberry question:

google: vision automation

Hi

DOes anybody knows if it's possible to use a raspberry with google vision? or any project similar to inspire to me?

Thank's guys

Hi @gohan

The idea is to read the products non stop...I would like to use a slide with a sensor that detects the tray and make the photo. More than 30 per minute

Thank's

Hi

I would like to start a project reading the fruit tray labels, so I can scan the weight and see if they're overcharging me.
The idea would be to pass a tray of fruit underneath the camera and have it photographed... so that the whole purchase and then be able to read the labels.
Has anyone done anything similar? I don't know how to start,

Thank you very much

Eduard

Any one knows how it works A6? any example or sketch? I have one but I have no idea how it works.

Thank's again guys

Hi @gohan how did you do a timer? I have no idea how to do it.

Thank's

@gohan said in Help with a project sending images:

r even lower power consumption. Then it all depends on how big you

Yes, we could find a pi with low consumption, the problem is how to put the system in sleep mode for example at night...to reduce even more the consumption

Thank's every one

Hi,

I did a project that sends images to a webservice through 3g dongle.

I used a Raspberry and works perfect, but the problem is the rasp has to be in the middle of a field without energy. I tried to use a solar panel, but the high consumption makes this configuration not viable.

I want to do it with an arduino, anybody has experience doing that? maybe could help to us and making a small budget because is a concept proof and we do not have an enterprise budget. ;-)

Thank's

Hi
Yes I already sent a question tonthese guys but the answered without any constructive answer... :-(

I'm trying to connect with a 20k resistence and power with 3.3v but no anwer from the sensor

Hi,

I'm trying to connect this sensor to measure the leaf moisture. This sensor is one of the most important leaf sensor of the market.
https://www.decagon.com/en/canopy/canopy-measurements/lws-leaf-wetness-sensor/


I used this code to read:

{
  Serial.begin(9600); //Start Serial Port with Baud = 9600
}

void loop()
{
  Serial.println("Leaf Sensor Arduino Data Logger");  // AgriHouse.com 
  Serial.println("\nAnalog Pin #\tRaw Value\tPercent");
  Serial.println("------------------------------------------");
  for (int i = 0; i < 10; i++)
  {
    int val = analogRead(LeafSensor1);           //Read Leaf Sensor Pin A0
    
    int per = map(val, 0, 1023, 0, 100); //Convert to Percentage
  
    Serial.print("A0\t\t");
    Serial.print(val);
    Serial.print("\t\t");     
    Serial.print(per);           //Print Percentage Analog Value
    Serial.println("%");         //Print % Sign and Newline
    delay(1000);                 //Wait 1 second, then repeat
  }  
}

// Note: Leaf Sensor Connection
// Connected Leaf Sensor to 3.3 vdc power source and ground (gnd)
// Leaf Sensor connected to analog input port:A0 

// Note: How to read the leaf sensor signal val
// Leaf Sensor Not Affixed (NA) is the highest %. 
// The Affixed (A) % is less than NA. 
// Thus (A%<NA%) or (Aval<NAval) means more water in the leaf i.e.(thicker leaf). 

 //Notes: 
 // The arduinos analog inputs have a 10-bit resolution. 2^10 (converting to decimal system) = 1024

 // So that's 1024 states, divided in the range 0-5V. 5V / 1024 states = 0,00488V/state (4.88mV/state).
 // The leaf range is approximately 1.45 to 2.21V @3.3V = 0.77V or 157 states @ 4.88mV ea.
  

 // Basically means that when you read the arduinos analog inputs you'll get a value between 0 and 1023. 
 // Each increase in this value signifies rougly a 4.88mV increase in the voltage measured.

But I tried many combination to wire it, but I could not reach any reading from the sensor.

Does anybody knows anything from this sensor? or any idea?

Thank's

@AWI said in Watermark arduino 3.3 headache:

how us

Hi @AWI

I tryied this hardware as a watermark: WATERMARK 200SS from http://www.irrometer.com/sensors.html

My logger is a Sodag One based on arduino:
http://support.sodaq.com/sodaq-one/

I followed this schema to wire it because the One is working at 3.3V

and this sketch

I don't know if you need more info about it.

Thank's

Hi all,

I'm programming a watermark sensor and an arduino 3.3v. I tried a lot of sketches and connections and did not work.

Anybody used this sensor? does anybody has docs or sketch or pictures connecting...?

I'm desperate!!!

thank's
