PHP and Mysql
Create a database with three tables: temperature, humidity, pressure. Use the following code:
CREATE TABLE `fasensor7`.`temperature` ( `id` INT( 255 ) NOT NULL AUTO_INCREMENT , `timestamp` VARCHAR( 255 ) NOT NULL , `temperature` VARCHAR( 255 ) NOT NULL , PRIMARY KEY ( `id` ) ) ENGINE = MYISAM ; CREATE TABLE `fasensor7`.`pressure` ( `id` INT( 255 ) NOT NULL AUTO_INCREMENT , `timestamp` VARCHAR( 255 ) NOT NULL , `pressure` VARCHAR( 255 ) NOT NULL , PRIMARY KEY ( `id` ) ) ENGINE = MYISAM ; CREATE TABLE `fasensor7`.`humidity` ( `id` INT( 255 ) NOT NULL AUTO_INCREMENT , `timestamp` VARCHAR( 255 ) NOT NULL , `temperature` VARCHAR( 255 ) NOT NULL , PRIMARY KEY ( `id` ) ) ENGINE = MYISAM ; CREATE TABLE `fasensor7`.`light` ( `id` INT( 255 ) NOT NULL AUTO_INCREMENT , `timestamp` VARCHAR( 255 ) NOT NULL , `pressure` VARCHAR( 255 ) NOT NULL , PRIMARY KEY ( `id` ) ) ENGINE = MYISAM ;
Add 2 files to your server: connect.php and add.php:
<?php include("conec.php"); $link=Conection(); $timestamp=date('Y-m-d H:i:s'); mysql_query("insert into temperature (timestamp,temperature) values ('$timestamp', '".$_REQUEST["temperature"]."')"); mysql_query ("insert into pressure (timestamp,pressure) values ('$timestamp', '".$_REQUEST["pressure"]."')"); mysql_query ("insert into humidity (timestamp,humidity) values ('$timestamp', '".$_REQUEST["humidity"]."')"); mysql_query ("insert into temperature2 (timestamp,temperature2) values ('$timestamp', '".$_REQUEST["temperature2"]."')"); mysql_query ("insert into dew (timestamp,dew) values ('$timestamp', '".$_REQUEST["dew"]."')"); mysql_query ("insert into light (timestamp,light) values ('$timestamp', '".$_REQUEST["light"]."')"); ?>
