  12. Wireless, Battery-less sensor Power Supply (solar) Power supply traditional Receiver Transmitter Sensor (temp) Description: This is a wireless, battery-less temperature sensor utilizing energy harvesting techniques (piezoelectric, seebeck effect, solar) most likely solar. The sensor will transmit to a receiver which will display the data. Performance features: This product is characterized by a long maintenance free life. Currently wireless sensors have batteries which need to be replaced driving up maintenance costs. Power source: The power source is most likely solar with a energy management circuit using super capacitors. The power supply will be able to handle periods where no power is being supplied. Modes: The sensor is a dumb sensor and will be in transmit only. The sensor will have a duty cycle with a sleep period and only transmit for milliseconds at minute variables. User interfaces: The receiver will display the temperature. A Good Fit: This project is a good fit because it plays to our collective wireless strengths and interest in nontraditional power sources. This project is also paid for.

  14. Proposed Product Summary Wireless/battery-less temperature monitor. System will have a base unit that will display environmental measurements from a remote sensor. The sensor will be solar powered. The monitor will operate on 120VAC. The sensor will require no operation/maintenance once setup. Temperature display will be accurate. The primary benefit is the ability to have a wireless sensor that requires no power source.

Energy Source……………… Product Life…………………. Distech, powered by Enocean Multibillion dollar industry Approximately $30.00~$40.00 per sensor / display side North America New and existing buildings Sensor for HVAC controllers > 100,000 Sensor Side: Solar Display Side:120VAC 10 years

  16. Sensor side will function strictly off of a solar power/capacitor combination Display side will run off of 120VAC Sensor side max power in microwatts Both sides use 3 volt logic Project will contain two PCBs, one on the sensor side and one on the display side Sensor PCB will be no more than 100mm2 Max cost to manufacture will be less than $60.00 total Product will have a ten year lifespan Product will be covered under warranty for one year Standard Requirements

  17. Performance Requirements • Low Power (Solar, Energy harvesting) sensor side (uW) • 50/50 available power, continuous operation enabled by a super capacitor • On/Off switch on display • Address switches on sensors • Battery-less, no wires on sensor, low maintenance costs, long life • Sensor has sleep and transmit modes • Receiver displays different channels • 150 m range • 1 degree C accuracy for -20 to + 100 degree C • Displays temperature on built in display • Outputs temperature data on a display • Unique because of the long maintenance free lifespan, this is an emerging field in building controls which companies are just now starting to explore

  21. Patent Search Result 1 • Patent Number: 5,572,190 • Date: November 5, 1996 • Title: Batteryless sensor used in security applications • Summary: A batteryless sensor includes a piezoelectric crystal to convert a movement of a door or window to power to radiate a coded RF signal to a receiver, a distance away. The receiver may monitor a multiplicity of sensors to identify a source of an intrusion.

  22. Patent Search Result 2 • Patent Number: 7,081,816 • Date: July 25, 2006 • Title: Compact Wireless Sensor • Summary: Wireless security sensors for insertion within window and door frames as a means for detecting intrusion.

  23. Patent Search Result 3 • Patent Number: 7,019,241 • Date: March 28, 2006 • Title: Energy-autonomous electromechanical wireless switch • Summary: Has transducer element for converting mechanical to electrical energy, and has actuating panel for introducing the mechanical energy, and has sensor for each actuating panel for detecting the switching command. Electronic system generates and emits a wireless signal. Mechanism deflects the forces introduced by the actuating panel onto the transducer element.

  24. Ethical Issues • The wireless signal could cause interference with other electronics (i.e., Cellular phones, pacemakers, etc.) in the area, causing problems to the users of these devices • The temperature reading must be measured to ≤1% to accurately read HVAC conditions which otherwise could lead to pipe damage and/or explosion
