Jennic ZigBee PRO Wireless Sensor Network Platform

Wireless Sensor Network (WSN) refers to a group of nodes (with some sensors on-board) connected through a wireless link and thus forming a cluster/ network to perform specific task(s) like asset management, smart lighting, remote control, etc. ZigBee PRO is the latest version of ZigBee protocol which is based on IEEE 802.15.4 standard. This WSN platform from Jennic enables users to create ZigBee/ IEEE 802.15.4 based WSN applications. The nodes in this kit have sensors for temperature, humidity and ambient light on-board. The wireless networks formed operate in the 2.4 GHz unlicensed ISM band and support a data-rate of 250KBps. Application development is done in C/C++ on Eclipse IDE with ZigBee PRO libraries provided by Jennic.
The work is carried out in this lab is mainly in the domain of developing applications for energy management.

TelosB IEEE802.15.4 based motes with WiEye PIR Sensor

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.

Microcontroller Based GSM, RFID kits

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.
