Status Implemented


  • Connect homes to detect emergency events and alert residents via phone or app, and initiate contacting first responders
  • Demonstrate how to extend a connected safe home to everyone at a low-incremental cost
  • Focus on seniors, their care givers, and property managers


  • Creating a standard process for collecting and storing data from various sensors operating on different platforms
  • Piloting new applications of existing technology
  • Scaling the project beyond the pilot stage across the County
  • Collaborating with service providers to maximize opportunities for seniors to connect with services via


Major Requirements

  • Collaborate with seniors and experts on seniors and aging and emergency management to identify potential needs of seniors living independently
  • Engage #IoT experts to develop #IoT solutions to address the needs of seniors living independently
  • Pilot #IoT solutions in the apartments of seniors living independently
  • Measure ongoing success of the program and adapt program as necessary

Performance Targets

Key Performance Indicators (KPIs) Measurement Methods
  • Reduced number of senior deaths from in home accidents
  • Mortality statistics from the state

Standards, Replicability, Scalability, and Sustainability

  • Our project uses established Machine-to-Machine communications standards (MQTT) to provide real-time data to data consumers
  • Actuators and Dashboards can subscribe to data streams from any data producer
  • Most of the components of the sensing habitat are composed of open-source software and off-the-shelf hardware, allowing ready replicability
  • The data habitat is based on a MQTT transmission protocol, with consumers subscribing only to relevant feeds, promoting scalability

Cybersecurity and Privacy


  • Help aging households in Montgomery County live independently more confidently
  • Connect vulnerable residents in the County to critical services more efficiently
  • Prevent deaths from common accidents among seniors (e.g., fall cannot get up, unnoticed gas leak)


  • Phase I Pilot/Demonstration:
  1. Network infrastructure developed
  2. Sensors deployed in volunteer resident homes
  • Phase II Deployment:
  1. Continue developing new sensors to pilot
