Long-range LoRa sensor
Intermediate45 min
A standalone sensor sending a few bytes very far, very rarely, on a tiny power budget.
What you get
Readings received kilometres away, on a battery-friendly energy budget.
Parts (simulated)
- Built-in RF/SDR lab
- Simulated sensor
- Gateway receiver
Nothing to buy: every component here is simulated in the browser.
Project steps
- 01Pick the licence-free band and spreading factor.
- 02Send a short measurement frame.
- 03Increase distance until reception breaks.
- 04Trade off range, throughput and power draw.
What you learn
- Spread spectrum
- Range / power trade-off
- Short frames and duty cycle
