UPDATE: These MK808 and MK908 devices may work well for you, however, note that we’ve had much better reliability and stability using YoctoHub WiFi and Ethernet devices. Here’s a video tutorial on connecting those YoctoHubs and Raspberry Pis to Valarm Tools Cloud. Valarm software is used with these for long-term field deployments in the petroleum industry, upstream oil&gas, and governments to monitor environmental factors like water:

 

Have you seen how small mini PCs are? Incredible, they are about the size of a stick of gum. That is all that’s needed for a dual (MK808) or even quad-core (MK908) processor, RAM (1GB or more), & input/output (I/O) ports: powerful enough for Valarm! Below is a video from Valarm’s YouTube channel about these Android devices.

 

 

We’ve been running a series of tests with a variety of sensors like thermocouplesvolatile organic compounds (VOCs)electrical resistance, and water. These micro-Androids make for great dedicated devices for deployment in the field for applications like remote environmental monitoring and air quality (outdoor and indoor air quality, IAQ).

The MK808B has WiFi built in and you can plug in a USB ethernet or 3G/4G device if needed in your scenario. Valarm uploads your data to the Valarm Tools cloud servers where you can map, graph, analyze, and download all of your sensor data.
