Seeeduino Stalker
Seeeduino Stalker is a feature rich Arduino compatible Wireless Sensor Network node with Data logger functionality. Its modular structure and onboard peripherals makes it convenient to log time stamped sensor data on a periodic basis. Seeeduino Stalker comes with a Temperature sensor, RTC with backup power, SD Card Socket, Bee Socket and Solar LiPoimer Ion Battery Charger. The Seeeduino Stalker is a good candidate for all your tracking, monitoring and control projects.
Please note that the current (and also the latest) version of is Seeeduino-Stalker v3.
