ThingSpeak vs Conrad Connect Comparison: Everything You Need to Know Before Choosing

ThingSpeak is an IoT analytics platform service from MathWorks that allows users to aggregate, visualise and analyse live data streams from sensors and devices in the cloud. Engineers, researchers and students building connected prototypes often need a straightforward way to send data from microcontrollers or gateways to an online store and then analyse it without setting up their own servers and databases. ThingSpeak addresses this by providing ready-made channels to which devices can post data over simple HTTP or MQTT interfaces, with the data instantly available for charting and processing. Its distinctive feature is tight integration with MATLAB, which lets users write and run MATLAB code directly in the cloud to analyse incoming data, perform calculations and trigger actions. This combination makes ThingSpeak a practical bridge between device-level experimentation and sophisticated numerical analysis, particularly for those already familiar with the MathWorks ecosystem. Key capabilities include data channels with multiple fields, public and private channel settings, real-time visualisations and customisable plots, and MATLAB Analysis and MATLAB Visualisation apps for scheduled or on-demand processing. Actions such as React, TimeControl and ThingHTTP allow users to respond to data conditions by sending alerts, calling web services or posting to social media. The service supports popular hardware including Arduino, Raspberry Pi, ESP8266 and ESP32 boards, and data can be exported or accessed via a REST API for use in other tools. Integration with MATLAB desktop and Simulink supports more advanced modelling and algorithm development. ThingSpeak is delivered as a hosted cloud service and is widely used in education, academic research, prototyping, environmental monitoring and small-scale commercial IoT deployments. Licensing distinguishes between free non-commercial use with message limits and paid commercial, academic and student licences with higher capacities. Pricing starts from around USD 79 with a free trial available; there is no permanently free version listed here.
