I'll ask 4 short questions to better understand your project requirements.
Question 1: For the core controller and radio, would you prefer an integrated ESP32 with LoRa (e.g. a board like the Heltec ESP32 LoRa or TTGO T-Beam) or a separate LoRa transceiver paired with a standalone ESP32?

Question 2: What LoRa frequency band do you plan to use? Options include 433 MHz, 868 MHz, and 915 MHz.

Question 3: For measuring temperature at the surface and 3 m below, do you want to use two separate waterproof sensors (e.g. DS18B20) or consider any alternative sensor type?
Question 4: Would you like guidance for the power management circuitry — including battery charging and voltage regulation — to handle the 3 × 18650 battery pack and 5 mini solar panels for powering the ESP32 and sensors?

- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
