ESP32 Buoy Project Setup
Thought for 25 sec
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?
"I want a separate LoRa transceiver paired with ESP32 to reduce cost"

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

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?
Use two water-proof sensors
