A temperature sensor, microcontroller, wireless module, battery, case, and miscellaneous parts meant each node in the sensor grid would cost about $10.

Now you can build your own room temperature monitor using an Arduino board. The circuit is a combination of an Arduino UNO board, LM35 temperature sensor, and a 16×2 Hitachi compatible LCD. It will ...

With over 20 unique sensor types, and the ability to be used with several different development platforms, Tarts wireless sensors allow for endless sensing, monitoring and control possibilities.

Hm. NiMH may be worth looking into. Hadn't thought of that. For my totally-hypothetical at this point wireless soil moisture sensor project, I've been thinking about using supercapacitors.

Arduino boards are largely based on Atmel’s MCUs, but mostly don’t have wireless due to their size and cost constraints. With devices becoming more connected, Atmel will be able to package ...

Electronic enthusiasts may be interested in a new Arduino-based multitool equipped with a full-color screen and touch base control system, designed to simplify and open source the development of ...

Arduino was once thought to be difficult to wirelessly connect to the internet, then the Arduino Yun came along and wireless connectivity got a whole lot easier. What they did was integrate a Wi-Fi ...

In my reviews of existing arduino projects like this I found that the wireless recommended is to use the Zwave/Zigbee, RF24LR, or 433mhz type modules and bridge them back through a raspberry pi or ...
