how to enter into deep sleep mode

[ps_anu]

Hi, I have interfaced the nRF52832  with  temperature sensor via i2c(MAX30205 temperature sensor) . I am advertising only when it become low temperature( setting the threshold ) using ble_app_beacon 

1. To check the threshold  i am using time, every one minute it will check the threshold condition 

In this case , which one will be suitable for my application ? Suggest me pls

1. DETECT signal ,

2. ANADETECT signal.  

Thanks&Regards

Hello,

The sensor is an I2C sensor? so it will output a signal (actively) when the threshold is reached? Or do you need to trigger the read from the nRF?

If you need to trigger this, and you trigger it from a timer interrupt, you need to use system on sleep, because the timer's can't run in system off mode. 

If it gives an interrupt on it's own, you can go to system off mode, and enable one of the pins (the sda pin, for example) as a wakeup pin.

Best regards,
