@berkseo Thank you for your answer Good continuation on your nice project.
This is a temperature and humidity sensor running then cr2477 batteries (950mA).
The Board radius is 35mm.
Support:
Upgrade by air(only extended version). Led highlighting the status of the connection to the network, sending the readings from the sensor. Parameter adjustment via the controller: the LED is on / off, the interval of sending the temperature and humidity readings is 1min - 4 hours, the interval of sending the battery charge is 1 hour - 7 days. Everything is simple and tasteful :), very stable stuff ..
