You can easily connect to a Sparrow IoT server, send data, and receive commands with this library.
-
Reliable WiFi connecting
-
Memory caching, if the wifi is temporarily disconnected
-
Easy interface for setup, data sending, and receiving
-
Technologies: Arduino (framework), C++
To create a reliable and easy-to-use data communication library for the Sparrow IoT Platform as the Blynk Library or the ThingSpeak Library. This library manages entirely the WiFi connection and the communication with the server and makes the IoT data logger development much easier.
