My new development: a mini temperature and humidity sensor with an electronic ink display(ver. nRF52832). Very low power consumption! The prototype is ready, software is testing, the energy consumption tests have been successfully passed.
Very easy to program in Arduino IDE.
A great device for learning nRF52832.
I have these devices planned as control devices for heating batteries in every room of my house.
List of components that are present at the sensor:
...I hope this development will deserve your like
