Usage Scenario
Smart Agriculture and Irrigation Automation
NetRelay in greenhouse, garden and field irrigation; It automatically manages valves and pumps according to soil moisture, wind and sunrise/sunset data. Scheduling continues with RTC even if the internet goes down — 100% local operation without using the cloud.
- • Analogue soil moisture / light / temperature / pressure / humidity with external module
- • Irrigation timing without internet with additional DS3231 RTC
- • Single cable feeding to remote valve boxes with PoE
- • Telemetry to central agricultural panel with MicroSD log and MQTT
Park garden irrigation example
The soil moisture sensor starts irrigation when it drops below the set threshold or every other day at 20:00; It turns off the relay after 30 minutes. If the wind speed is high, it postpones irrigation.
Greenhouse safety
When the wind exceeds 20 km/h it triggers the electric shutdown system; Manages fan or heater relays at humidity and temperature thresholds.
