ThingSpeak
R2026bThingSpeak™ is an IoT analytics service that allows you to aggregate, visualize, and analyze live data streams in the cloud. ThingSpeak provides instant visualizations of data posted by your devices to ThingSpeak. You can process the data in real time and analyze it online.
You can send data from your Arduino® board directly to ThingSpeak using REST API or MQTT. With ThingSpeak, you can store and analyze data in the cloud without configuring web servers, and you can create event-based triggers based on the incoming data from your Arduino hardware.
