Self-powered wireless sensor network (WSN)
2.4 gHz | EH-Link™
MicroStrain
In applications with vibrating machinery or structures under load, the EH-Link™ can be self powered from a tiny generator. The EH-Link™ can operate from high impedance AC or DC sources, in the range of 5.0 V to 20 V.
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-LinkTM 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.
