hi I have a web site that checks a service and display a value 0 or other number. if 0 that means the service is down. if other number such as -1 that means the service is up.

how can I monitor that and set a sensor to notify me for changes?

I encourage you to change the web-page to display the value in a format that PRTG can natively understand, for example:

Data that is compatible with the HTTP Content Sensor should look 

<html>
 <body>
  Description: Script gives back current status of disk free (%) and CPU usage (%).
  [85.5][12.0]
 </body>
</html>

Or, if you want to use the HTTP Data Advanced sensor, the XML-encoded data should look like this:

<?xml version="1.0" encoding="utf-8" ?>
<prtg>
	<result>
		<channel>Channel 1 (float)</channel>
		<value>12.34</value>
		<float>1</float>
	</result>
</prtg>

Or, if you rather use JSON:

{
  "prtg": {
    "result": {
      "channel": "Channel 1 (float)",
      "value": "12.34",
      "float": "1"
    }
  }
}

For more details:

I encourage you to use a lookup after you've created the sensor to display a state in PRTG (instead of 1 and 0):
