Yocto-CO2 Ethernet


Combine a Yocto-CO2 with a YoctoHub-Ethernet to get an autonomous appliance with built-in network connectivity:



The Yocto-CO2 device will let you measure the quantity of carbon dioxide (CO2) in ambiant air via an USB connection, as well as record it on its internal flash for later retrieval when connected again.

This device is ideal to precisely monitor the air quality in residential, commercial and industrial spaces, as well as potentially dusty air ducts used in HVAC (Heating Ventilation and Air Conditioning) systems. The sensor used in this device uses non-dispersive infra-red absorption (NDIR), and requires no maintenance. It provide precise measurements already within the first minute after power on.

The YoctoHub-Ethernet is a Fast-Ethernet module that can host three Yoctopuce modules to access them remotely. It can be powered either by a USB Micro-B cable, or directly from the Ethernet cable (PoE compatible with 802.3af standard).

Three Yoctopuce modules can be connected directly, one of which can be fixed directly on the YoctoHub-Ethernet and connected using a Board2Board-127 connector. More devices can be connected thanks to the YoctoHub-Shield extension. The YoctoHub-Ethernet can power Yoctopuce devices up to 2A.

Android™ app Valarm Pro v1.2 now includes support for the Yocto-CO2 sensor! Monitoring CO2, whether you’re using it for agricultural or ornamental purposes, or producing it due to industrial or food production activities, or simply living and working in enclosed spaces of any kind – can be critical for human health, productivity, and creativity. With Valarm you can monitor CO2 in real-time, record data to visualize trends, and trigger alerts at configurable levels.
