EH-Link? Energy Harvesting Wireless Sensor Node - 1

Wireless Sensor Node Features & Benefits no batteries required, EH-Link™ is self powered from high impedance AC and DC sources or low voltage DC sources as out-of-the-box wireless sensing capability for most analog 2.4 GHz direct sequence spread spectrum IEEE 802.15.4 radio operates in license free band world wide communications range up to 70 m line of sight supports auxiliary storage options such as supercapacitors or rechargeable thin film batteries (TFB) supports multiple nodes at sample rates up to 2048 Hz environmental monitoring conditioned based maintenance (CBM) structural health monitoring (SHM) building automation monitoring industrial processes cold storage monitoring Sensor Support external strain gauges bridge sensors (pressure sensors, load cells, etc.) pulsed DC excitation pin to provide power for external onboard relative humidity & temperature sensor onboard three axis accelerometer Data Sheet 30 The EH-Link™ wireless node is a self powered sensor, harvesting energy from ambient energy sources. EH-Link™ is compatible with a wide range of generator types, including piezoelectric, electrodynamic generators, and thermoelectric generators. In applications with vibrating machinery or structures under 00 load, the EH-Link™ can beself powered from a tiny generator.The EH-Link™ can operate from high impedance AC or DC sources, System Overview The ultralow voltage (ULV) input of the EH-Link™ allows powering from Peltier Thermoelectric Generators (TEGs), or thermopiles. This ULV input can power the EH-Link™ from as low as 0.02 Vdc and up to 0.6 Vdc making the wireless sensor node operable from thermal gradients below 8 °C with TEGs. Using the high impedance 5-20V harvester input, the EH-Link™ can also operate in ambient light levels well below that required for solar cell use with traditional electronics. Sophisticated energy conversion and conservation methods allow the EH-Link™ to operate with a fraction of the power normally required for a wireless sensor node. The EH-Link™ wireless sensor node is versatile and is designed to operate as part of MicroStrain's 802.15.4 wireless sensor network. Each node in the wireless network is assigned a unique 16 bit The EH-Link™ Pioneer Kit, MicroStrain part number 6320-0041 includes 1 EH-Link™ wireless sensor node, 1 solardemo harvester and 1 TEG demo harvester, enabling users to set up an Energy Harvesting demo in minutes. Harvester Support Standard Voltage Input • AC or DC sources that produce > 5 V instantaneous open circuit voltage Ultralow Voltage Input • thermoelectric generators • low voltage solar cells MicroStrain* Little Sensors.
