TelosB is an IEEE 802.15.4 based WSN platform. These devices have USB programming capability, an IEEE 802.15.4 radio with integrated antenna, a low-power MCU with extended memory (of 1 MB) for data logging. They run TinyOS on them and have the capability of integrating more sensors for custom applications. The WiEye sensor has a long-range PIR sensor which can detect human presence up to 20-30 feet distance. This sensor board also has visual light and acoustic sensors enabling improved detection. These sensors can be used for surveillance and security applications.
These kits have an 8051 microcontroller interfaced to an RFID/ GSM modem. They also have some other peripherals like RTC, stepper motor controller, etc. all integrated on a single board making it suitable for small scale embedded applications for control and communication.
