Hardware

LoRa in the crop. Relays at the pump.

Relay count is locked to the manufacturer record for that serial — never to the QR payload alone.

LoRa transmitter

A field node for soil moisture and DHT11 temperature/humidity. It wakes, measures, sends, and sleeps. Battery and solar keep it in the row without a farm Wi-Fi run.

Soil moisture percentage at the plant.
Air temperature and humidity from DHT11.
Battery and last-seen status in the dashboard.
Many transmitters can share one relay channel.

Farm receiver

The station that listens to transmitters and drives irrigation relays. Pair it with a QR code, a name, and a PIN. Models differ only by verified relay count.

Local automatic watering even if the cloud is quiet.
Manual start/stop with a duration cap.
Weekly schedules stored on the account and synced to the field.
Firmware listed when a release is published for that model.
