GPRSbee

Seeeduino Stalker is a feature rich Arduino compatible Wireless Sensor Network node. It's 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. Because it has a bee socket you can use the GPRSbee as an alternative for the GPRS Shield. This would allow you to run it on battery power.

When you use it in combination with the GPRSbee, you can transfer your data from anywhere, even from moving objects.

Just plug the GPRSbee into the bee socket and plug a LiPo battery into the GPRSbee. Use the jumper cable to connect the GPRSbee to the BAT socket on the Stalker.

If you connect a Solar panel to the Stalker or power it over USB, it will charge the LiPo battery.

If you want to use the software on/off function of the GPRSbee you have to connect a wire from PIN9 on the bee socket to a digital pin on the Stalker (in our example sketches we use PIN6 on the Stalker).
