is it possible to send the data by using interrupt

[ps_anu]

hi...

i am using nrf52832 and sensor ......... is it possible to read the data by interrupting the sensor 

for example .... 

 if i am using temperature sensor if the value goes to below 37 degree then it should send the data to uart ble (via app) is it possible

Sorry, I don't understand your question!

An "interrupt" would normally be a signal from a sensor to the microcontroller - so you wouldn't "interrupt the sensor".

Some temperature sensors can be programmed with (a) threshold(s) - and may be able to  generate an interrupt to the microcontroller...

You would have to study the particular sensor's documentation for details.

Otherwise you would just read - or "poll" - the sensor at a suitable, regular, interval and your code would compare each reading against your threshold, and take whatever action is required.

yeah you are correct  by using threshold ... how do that

how to declare the threshold 

i am getting error on this

Show what you did.

Show what error(s) you got.

Use copy & paste - don't manually re-type.

How to properly post source code:

[ps_anu]

static void value_from_sensor()
uint16_t threshold;

{
value_from_sensor = read_sensor_data();

if( value_from_sensor > threshold )
{
 printf("Data send.. \r\n");
}

You need to go back to your 'C' textbook and see how to properly create a 'C' program.

Again, this is basic 'C' coding - nothing specific to Nordic.

It is generally easier to learn the language on a PC or similar - where you have more convenient tools, and without all the added complications of embedded microcontrollers.

Here are some 'C' learning & reference materials - including a free online textbook:

static void value_from_sensor()          <-- is this supposed to be a function prototype?
                                             If so, it should have a semicolon

uint16_t threshold;

{
    value_from_sensor = read_sensor_data();   <-- From above, value_from_sensor is the name of a function
                                                  You cannot assign a value to the name of a function!

    if( value_from_sensor > threshold )
    {
        printf("Data send.. \r\n");
    }
