what's that I juste done a quick google's search, but nothing interrested....

can you explain what's that?

Dallas's librairy?

Pas de problème BTguillaume, on vas pouvoir s'entre aider, et non j'ai pas encore fait l'achat du matériel vue que je ne c'est pas encore exactement ce qu'il me faut, aussi merci à tous et non je ne cherche pas de réponse toute cuite, mais une grande aide vue que je suis pas super fort en arduino, mais je suis motiver, et sur tous obliger de le faire, mais cela m'intéresse beaucoup !

Aussi le mieux entre le capteur LM35 et le DS18B20 c'est le quelle ?

J'ai commencé avec un duemilanove et enc28j60.

le code affiche la température en pesant sur le bouton . Il faut un ds18b20 (1-wire) sur une entrée numérique (la 3) dans l'exemple.

Pour introduire une variable quelqu'un peu me dire ou commencer. Le test serait avec l'exemple du site :

if (x > 120){
  digitalWrite(LEDpin1, HIGH);
  digitalWrite(LEDpin2, HIGH);
}    

Si je comprend bien une valeur plus grand que 120 fera réagire la ledpin 1 et 2?

Il faut aussi mettre #define ledpin1 et 2.
Code:
EtherShield es=EtherShield();

// prepare the webpage by writing the data to the tcp send buffer
uint16_t print_webpage(uint8_t *buf);
int8_t analyse_cmd(char *str);
// get current temperature

#define TEMP_PIN  3
#define LEDpin 1
#define LEDpin 2

void getCurrentTemp( int *sign, int *whole, int *fract);

La condition sera dans le loop ou pas?

Meci

avec le enc28j60, il y a un exemple déjà fait. Reste qu'a adapter les valeurs + et - pour notification.

Bonjour Simon, je cherche à faire le même truc (du moins très similaire) On peut travailler en parallèle sur ce projet.

Je ne sais pas si tu à<as des équipements arduino?

J'ai un Ethenet shield monté sur un Duemilanove. L'exemple ''web temperature'' est un bon départ selon moi. Tu cliques sur le bouton et la température affiche à l'écran. Il faudrait juste ramasser les infos pour établir un seuil haut et un seuil bas pour l'envoie de email.

L'envoie de sms peux être simple selon le fournisseur, mais en gros ''ton_numeros_de_tel@ton_fournisseur'' ex: 8005559214@rogers.net envoie un email sous forme de sms sur un téléphone. Sinon il y a des serveurs qui peuvent le faire. Donc 2 email, un sur ton cell et un sur ta boîte courriel.

Peut-être commenceé avec le code du webserver et le modifier? Je vais l'afficher plus tard.

You really need a more powerful Arduino with more RAM (mega2560) or can try ksduino.org, http://open.sen.se/, https://www.thingspeak.com/ http://exosite.com/products/portals cloud. Ksduino and http://www.pushingbox.com/ support ENC28J60.

Duemilanove + ethernetshield enc28j60 should be a great setup?
12  Community / Exhibition / Gallery / Re: Arduino Webserver with Temperature Monitor / Control on: February 14, 2013, 07:41:52 am
Okay i think that would help.

I'm realy bad in programming, My project is to take the entire web temperature fo enc28j60 code and modify it to send email when the value is under or over the preset.



Thanks for help and shared links!
13  Community / Exhibition / Gallery / Re: Arduino Webserver with Temperature Monitor / Control on: February 13, 2013, 10:13:00 pm
Is this code source work if I only copy/pastre to my enc28j60 ethenet shield?

Does this thermostat can send email if the temperature range is below or under the value I preset?


Im very interrested to reproduce this thing, it's awsome! thanks for sharing and let me know!


It could be cool to share an HOW TO for beginners like me smiley
14  Topics / Home Automation and Networked Objects / web temp with enc28j60. Questions with programming on: February 11, 2013, 08:55:20 pm
Hi guys, I'm new here and realy poor in programming. I have a shield (enc28j60) and want to use it as a simple web temperature notifier using the web temperature code. I need to modify it with a over temp value and a lower temp value. Both give send me a email when temp is too low or too hight.

Exemple :
if temp is over 20 deg, send an email
If temp is under 15 deg, send an email



It's the only thing i need, can you some one help me with this problem?


Thanks a lot
15  Topics / Home Automation and Networked Objects / Re: Wifi Web Thermostat on: February 11, 2013, 08:22:09 pm
HI, I would like to do something similar using enc28j60 chip Arduino shield.

Only a web temperature notifier :

For exemple ,if temp is below 20 deg send an email. If temp is over 25 send an email again. Is it possible. If yes how should i do with this shield?


Thanks a lot my friend.
