Reply To: Which microcontroller for a field sensor that runs on a battery? It needs to last a year

Thank you so much, teacher. I asked the teacher, and there is already a LoRaWAN gateway on the department’s roof, nobody told me 🙂 I ordered a RAK3172, and when it arrives I’ll add it with OTAA and write back. I’ll keep the ESP32 on the bench for testing.
