What I am about to say assumes that table temp1 is a file.
If it is then:
1. At the end of script B ensure that temp1 is either deleted or renamed so that it doesn't exist anymore.
2. At the start of script B, "test" (see man pages) to see if the file temp1 exists and if it doesn't then "sleep" (see man pages) for, say, 600 seconds to sleep the script. Only when temp1 exists will script B continue processing.
The above also assumes that temp1 is created fairly instantly so will either exist or not exist. If temp1 is created slowly, then get script A "touch" (see man pages) a file to use as a flag to script B which can then "test" for the existance of the flag file instead. Script B should delete the flag file before it finishes.
Hope that helps (and I have succeeded in making that clear enough).
Post any further questions.

psensor-server
PSENSOR-SERVER(1) User Commands PSENSOR-SERVER(1)
NAME
psensor-server - Temperature and system monitoring Web server
SYNOPSIS
psensor-server [OPTION]...
DESCRIPTION
psensor-server is an HTTP server for monitoring hardware sensors remotely.
It provides a JSON Web service which can be used by psensor(1) to monitor remotely the hardware sensors of a computer.
It can provide information about:
* the temperature of the motherboard and CPU sensors (using lm-sensors).
* the temperature of the Hard Disk Drives (using hddtemp).
* the rotation speed of the fans (using lm-sensors).
It is also possible to connect to the psensor-server with a browser, a simple Web page is displaying the sensors information and the CPU
usage.
The URL http://hostname:3131/api/1.0/sensors/[id] returns a JSON object containing all information about a sensor. [id] is the uniq identi-
fier of the sensor.
Here is an example of the JSON object of type 'sensor':
{ "id": "lmsensor acpitz-virtual-0 temp1",
"name": "temp1",
"type": 257,
"min": 47.800000,
"max": 60.800000,
"measures": [ { "value": 47.800000, "time": 1311374873 },
{ "value": 49.800000, "time": 1311374878 },
{ "value": 49.800000, "time": 1311374883 } ],
"last_measure": { "value": 49.800000, "time": 1311374883 } }
Fields of the type 'sensor':
* id: the uniq identifier of the sensor.
* name: a humean readable name of the sensor (might not be uniq).
* type: the type of sensor. Look at src/lib/psensor.h for the
different types.
* min: the minimal value of the sensor.
* max: the maximal value of the sensor.
* measures: all measures of the sensor.
* last_measure: the last value of the sensor.
* time: the time of a measure as the number of seconds since
1970/01/01.
The URL http://hostname:3131/api/1.0/sensors returns a JSON array containing all JSON objects of type 'sensor'.
If run in debug mode, psensor-server can be stopped by sending an HTTP request with the URL 'http://hostname:port/api/1.0/server/stop'.

WARNING
psensor-server does not provide any way to restrict the connection to the HTTP server, worst, no effort has been made against malicious
HTTP attacks. You should make the psensor-server port available only to a network or computer you trust by using the usual network secu-
rity tools of the system (for example, iptables(8) ).
