SenseBulb Prototype 

 A new design of very  low power  LED lightbulb and wireless sensor computer  for Assisted Living  and Alzheimer's  patients. The SenseBulb has novel none contact sensors to detect incidents in the home, e,g, a door left open, cooker unattended  or somebody fallen in the bathroom. A text message is  sent to a mobile phone. SenseBulb is also useful for security systems in the home and office. 
 
SMS Messages from Sensebulb's GSM modem to iPhone. Alerts takes typically  only 15 seconds to detected and then be received by a remote mobile phone. Any mobile phone can be used to receive messages. This wireless technology, SenseDirect, uses an ARM7 microcontroller,   developed by Williams of Girton Labs, allows wireless sensors to be used with mobile phones with no dependency on Microsoft PCs, emails or personal computers. All that is required is a SenseBulb, and mobile phone with PAYG contract, £10/month or 3p/message with your own phone. Setup is done using an SMS message from your mobile phone, no pc required.  SMS messages can also be sent to landline phones, using text to speech conversion to provide a voicemail message.  SenseBulb tested  on Vodafone, Orange, O2 networks,  Dual Band GSM 900 and GSM 1800.

Details 

 

  SenseBulb, a low power, retrofit, smart light bulb with sensing abilities to save power and provide security alerts

  • Fits in an ordinary light socket
  • Power saving by using White LEDS,  controlled by thermal detection of people, 20% power of tungsten bulb used for same light output

 Provide occupancy monitoring for Alzheimer’s, elderly or disabled people, power management,  and security features to detect intruders and people

  • Stand alone bulb with audible and speech alarms, alerts sent via  SMS message
  • Uses advanced technology, but now low cost, remote heat detection as used in heat seeking guided missiles, allows object recognition in the home via thermal signature  (not PIRs)
  • technology for non visual object recognition
  • Examples: hot bath, gas hob lit, fridge door open, kettle, toaster, person fallen on stairs, human motion
  • Detects and alerts of abnormal conditions e.g. Person in bathroom for 1 hour at 3am – fall?
  • Sensor can detect hand waving – call for help – via SMS message
