How It Works
Wireless Sensor → Arka Gateway → Wi-Fi → Arka App
The sensor measures the temperature and humidty inside your refrigerator or freezer and communicates wirelessly with the Arka Gateway. The gateway connects to the internet through your Wi-Fi network so you can check temperatures and receive alerts while you're away.
No subscription is required for standard temperature monitoring and alerts.
The Arka Gateway requires power, a 2.4 GHz Wi-Fi connection, and internet access for remote monitoring and alerts. Sensor-to-gateway range can vary depending on walls, appliances, and other environmental conditions.
