Designed on the nRF52840 chip.

The temperature and humidity sensor SHT20/SHT21/SI7020/SI7021 is used.

Power sources used: CR2430/CR2450/CR2477.

Power consumption when transmitting data is 8mA, in sleep mode is 5uA.

For external interrupts to work, you must add

__attribute__ ((weak))
``` in the Winterrups.c file before the void GPIOTE_IRQHandler (){} function.
