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 

[awneil]

Go on:

value_from_sensor = read_sensor_value();

if( value_from_sensor > my_threshold )
{
    // The value is above the threashold;
    // take appropriate action!
}

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");
}
