Smart and seamless

75F’s suite of smart sensors gives building owners the power of IoT-connected devices for optimal efficiency and comfort in spaces where it matters most. Our wide range of sensors continuously monitor and provide data and visibility across your building and equipment in order to optimize your environment for efficiency, comfort, productivity and well being.

Measure to manage with the 75F Local Interface Sensor, a room sensor and user interface that takes highly accurate readings of temperature, humidity, and light.

 

Local Interface Sensor

Measure to manage with the 75F Local Interface Sensor, a room sensor and user interface that takes highly accurate readings of temperature, humidity, and light. This device can be extended to control HVAC equipment when connected to backend interfaces such as the 75F Hyper Stat or Smart Stat.

The Local Interface Sensor uses Bluetooth for provisioning and communicates with the 75F® Central Control Unit™ using a 900 Mhz wireless mesh network.
