The AWS IoT Device Shadow library enables you to store and retrieve the current state (the “shadow”) of every registered device. The device’s shadow is a persistent, virtual representation of your device that you can interact with from AWS IoT Core even if the device is offline. The device state is captured as its “shadow” within a JSON document. The device can send commands over MQTT to get, update and delete its latest state as well as receive notifications over MQTT about changes in its...

The Device Defender library enables you to send device metrics to the AWS IoT Device Defender Service. This library also supports custom metrics, a feature that helps you monitor operational health metrics that are unique to your fleet or use case. For example, you can define a new metric to monitor the memory usage or CPU usage on your devices. This library has no dependencies on any additional libraries other than the standard C library, and therefore, can be used with any MQTT client...

The C-GM Counter is a low cost (<50$) DIY Hardware & Firmware for building a Connected Geiger-Müller counter device to record beta-gamma radiation levels. The counter is the hardware part of the overall A-GM project aimed for providing a long-term continuous measurement of the radioactivity level. see also A-GM Manager at https://www.instructables.com/id/DIY-Radioactivity-Counter-IoT-and-Eco-system/ ** IMPORTANT ** : From v1.4, Arduino Nano require Optiboot bootloader to work, other...

The solution GreenHop aims to perform energy and environmental (temperature, humidity, dew point and atmospheric pressure) monitoring of the Data Center server room, providing energy efficiency indicators through green metrics for Data Centers. The GreenHop solution is based on open source software and hardware. The approach of using open source solutions enables its deployment easier and independently of suppliers at the same time makes the solution scalable to the needs of each...
