Build a Smart Farm: Auto-Irrigation with ESP32, a Soil Sensor & n8n
Keep your crops watered automatically. Read soil moisture on an ESP32, stream it to IoTFlow over MQTT, and let an n8n flow switch the pump when the soil gets dry.

Smart Buildings: Demand-Controlled HVAC with CO₂ Sensing & n8n
Fresh air without wasting energy. An ESP32 + SCD30 measures room CO₂; an n8n flow boosts ventilation only when it's needed, then eases off.

Smart City: ESP32 Parking Guidance with Ultrasonic Sensors & n8n
Help drivers find a free bay fast. ESP32 + HC-SR04 sensors report each parking bay to IoTFlow, and an n8n flow updates a guidance sign and logs occupancy.

Smart Home: Motion-Activated Lighting with ESP32 & n8n
Lights that follow you. A PIR sensor on an ESP32 triggers an n8n flow that switches a light on, waits, and turns it back off — no hub, no subscription.
