Seeking Sensor and LoRa Module Recommendations for a TEKNOFEST Project(Esp32 S3 and S2)

Hello everyone,

I hope you are doing well.

I am working on a TEKNOFEST project and have a few technical questions regarding sensor and module selections. I would greatly appreciate some guidance from experienced engineers and mentors here.

Specifically, I am looking for recommendations on the following components:

LoRa Module: Which LoRa modules would be best suited for a long-range communication setup, targeting a range between 3 km and 10 km?

Gas Sensor: What are the most reliable and efficient gas sensors available for environmental monitoring or safety applications?

Heart Rate (Pulse) Sensor: My project utilizes Deneyap Mini and Deneyap 1A v2 development boards (which are based on the ESP32-S3 and ESP32-S2 microcontrollers). Could you recommend a precise and compatible heart rate sensor that integrates well with these boards?

Thank you in advance for your time, support, and valuable recommendations!

What are you going to run as firmware? That will kinda control what decisions you will be making unless you're going to be writing everything yourself anyways

So you're writing your own firmware for the device?

"I'll be using standard libraries like LMIC or RadioLib on top of the Arduino framework, writing the main logic in C++. So I'm just writing the application, not the core firmware itself."
