This simple PHP-based application will let you monitor and graph sensors attached to a CBW device and send out email alerts when preset thresholds are crossed. Checkout this project, edit the config.json and email.json files in the conf/ directory and schedule bin/CBW.php to run periodically.

Application behavior is controlled via two JSON configuration files. You can edit those at any point in time as they are continously read by the app. The config.json file contains an array of sensor objects coming from one or more CBW devices. The email.json file contains email server related settings. In the `conf1 directory you will find sample files for both.

• sensor Name of the CBW's variable you ant to monitor. You can add one or more into the object.
• host IP or domain name of the CBW device. You can add variables from multie CBW devices.
• type This is not used right now, but it should name the physical attribute being monitored [temperature, humidity, voltage, etc.].
• name Name the sensor. This is free text, you can put in whatever you want.
• units Self explanatory - F, C, %RH, ...
• thresholdLow An alert will be generated when current value dips below this value. To disable put in false.
• thresholdHigh An alert will be generated when current value rises above this value. To disable put in false.
• notify An array of email addresses that should be notified. To disable leave the array blank [].

}

The easiest way to get this application going is to schedule it via cron or Task scheduler. You can also wrap the execution of CBW.php inside a while(true) loop and run it more frequently than once a minute.
