Our web-connected temperature sensors—essentially a thermometer connected to the internet—provide an affordable, reliable, and easy-to-use method of collecting, storing, and analyzing temperature data from a single apartment, many apartments, or even a portfolio of buildings throughout the city. We automate the entire process to provide tenants with the objective data they need to get their heat restored. 

Sensors can be installed throughout a building. Our sensors:

  • Include hourly temperature monitoring accurate to +/- .5 degrees celsius
  • Also include humidity monitoring (new!)
  • Incorporate a data logger and SD card, ensuring data is securely stored on the device even if internet connection is lost
  • Combine sensors, power, and internet all on one device

The sensors now come in two options, wifi* or 2G cellular. This means individuals with wifi can conveniently connect their sensor to their home wifi network. For individuals without home wifi, a SIM card and cellular data plan allows sensors to quickly access the internet, no matter where they are placed.

*For the 2017-2018 heat season, only wifi sensors are available for purchase. If you'd like to discuss purchasing 2G sensors, particularly for bulk orders or commercial uses, drop us a line at info@heatseek.org.

Web App

Heat Seek sensors detect and track heating code violations in real time by taking temperature readings once an hour. Individuals, landlords, lawyers, and even city inspectors can use our web portal to view their temperature data in real time and set alerts if the temperature drops below the legal limit. Tenants can also access a user-friendly temperature log that’s familiar to housing court judges. Heat seek sensors provide tenants with the objective data they need to get their heat restored. 

Each analysis we produce is carefully constructed--our team uses a number of tools, methods and programming languages to extract meaningful information from a vast amount of data. Check out our github to see examples of our methods, and the detailed steps we’ve taken to construct our analyses and visualizations.
