Semiconductor Solutions for IoT-Enabled Smart Buildings

Building automation and automated building control systems are nothing new – facility owners, operators and managers have long benefited from the operational and cost efficiencies of automating infrastructure such as security, lighting, heating, ventilation and air conditioning (HVAC), and more. Smart buildings, which connect building operations through the Internet of Things (IoT), simplify tasks like controlling building temperature, security and maintenance through mobile devices and computers.

The types of IoT sensors used in facilities management, building automation and smart building applications are limited only by your imagination. Prevalent use cases include:

  • Climate control, including temperature, humidity, vibration, etc.
  • CO monitoring
  • Electrical usage
  • Fire detection
  • Heating, ventilation and air conditioning systems (HVAC)
  • Lighting control
  • Occupancy
  • Predictive maintenance
  • Security and access control
  • Structural health
  • Water monitoring

Sensors are essential to making this possible, enabling collection and analysis of real-time data that can be used to:

  • Improve building energy efficiency and sustainability
  • Reduce maintenance costs with predictive maintenance
  • Optimize space utilization
  • Enhance tenant security, comfort and safety

The long range, low power ability for Semtech's LoRa® wireless radio frequency technology to penetrate dense building materials, and long battery life make it the preferred technology for IoT-connected smart buildings. Operating in the unlicensed spectrum, the LoRaWAN® protocol delivers efficient, flexible and cost-effective connectivity for indoor and outdoor IoT applications, operating seamlessly over public, private or hybrid networks. LoRaWAN is complementary to Wi-Fi, Bluetooth and Cellular.

Semtech’s portfolio also includes electrostatic discharge (ESD) protection solutions, touchscreen controllers and isolated power systems to automate lighting, heating, ventilation and more in connected smart buildings.
