ECT 300 is able to power wireless sensor nodes from only a few Kelvin temperature differentials. ECT 300 is based on a revolutionary ultra low voltage DC/DC converter which automatically starts operation at about 20mV input voltage. Output power depends on the actual temperature difference between both sides of the Peltier element and the Peltier element being used. ECT 300 Perpetuum Kit is designed as accessory for EnOcean’s self-powered sensor developer kit EDK 300. In combination with this kit a complete thermal powered radio sensor application can be evaluated and programmed. Typical application: A typical thermo-driven sensor consists of a sensor element (e.g. temperature sensor), a small Peltier element, a heat sink, the new DC/DC converter and a radio module (e.g. STM300). Powered by the temperature differential STM 300 will wake up on a regular basis, e.g. every 10s, acquire sensor values and transmit them via a radio signal over a distance of up to 300m. Typical application areas are home and building automation, automated meter reading, and condition monitoring.

Configure EVA 320 according to following application example - Temperature sensor: NTC on ADIO0 - Retransmit: every - Wakeup: 1s - Long term storage: EXT. (None) - Power Converter: ECT 300 plugged - Source: External source (Peltier connected) - Power Management: Off (On board) Peltier ECT 300 If heat sink has room temperature (e.g. 20°C) and you press one finger on the Peltier element above, the element will generate a few mV. ECT 300 will transform this to higher voltage and load short term capacitor on EVA 320. STM 300 will be powered by this energy and send telegrams. © 2009 EnOcean | www.enocean.com } EDK300 / EDK300C User Manual | Page 7/8 USER MANUAL ECT 300 PERPETUUM KIT 2. Check ECT 300 output voltage via voltmeter In order to see ramp up of CT 300 output voltage you can measure this between VDDLIM and GND. Since there is no long term storage connected (in this example) it will take some seconds until supply voltage is high enough and STM 300 will send telegrams.
