Wireless Sensor Networks

Wireless Sensor Network

Wireless sensor networks are built of resource constraint sensor nodes consisting of a processor, radio frontend, some memory, a means to connect sensors, an energy source and maybe a support for cryptographic operations. IHP provides a family of sensor node platforms with different processing and capabilities ranging from strong 32 bit RISC processors to constraint 16 bit microcontrollers. Typical applications are in the area of telemedicine, habitat monitoring and automation control.

Available Sensor Node Platforms

Trusted Sensor Node


A high-end node for secure data exchange for distances up to >500 m

Powered by a 32 bit LEON II processor

Hardware support for crypto graphic operations: AES 128 bit, Elliptic Curve Cryptography (ECC) B-233, SHA-1

Two wireless communication interfaces: IEEE 802.15.4 (Jennic Module), long range Bluetooth (> 500 m)

Multi-Radio Sensor Node


A low-power node for 2.5 GHz and below 1 GHz

Three low-power transceivers: Sub 1 GHz RF transceiver (TI CC1101), 2.4 GHz RF transceiver (TI CC2500), 2.4 GHz IEEE 802.15.4/ZIGBEE® RF transceiver (TI CC2520)

MMCX antenna connector for each RF transceiver

Interoperable with other IEEE 802.15.4 devices

Up to 25 MHz TI MSP430 microcontroller (16k RAM, 256k Flash)

µSD card slot

Adaptable Sensor Node Platform


A plug and play sensor node hardware which enables the engineer to select different modules (processors, radio front ends, etc.) for special applications in a Lego-like way.

Sensor node stack consisting of base board USB, MSP430 module and radio frontend 868 MHz
