LT1 Logging Transceiver

The LT1 is an MQ Telemetry Transport (MQTT) based compact logging transceiver for monitoring single or stacked sensors that measure environmental parameters. Connect an SDI-12 sensor, NMEA sensor and Tipping Bucket simultaneously

  • Local storage ensures data integrity
  • Based on a widely-adopted protocol for easy, secure scalability
  • Fits within existing enclosures
  • Easy setup with Bluetooth or FTS360
  • Cellular or GOES/EUMETSAT variants


In addition to its high-quality network connection hardware, the LT1 also stores sensor measurements on a user-accessible memory card. This ensures that data is not lost on the off-chance that there is a network service disruption. The LT1 and its supporting software have been designed and developed from the ground up to scale and operate securely on existing networks by leveraging a widely-adopted open-protocol platform in MQTT, scaling the number of units and users can be done easily and securely.

From a visualization and analysis perspective, the data flow from the LT1 can be ingested by most standardized systems, starting with the FTS back-end. As networks evolve, the LT1 is uniquely positioned to participate in the future of environmental measurement, as it holds the potential to evolve as needed.


About the size of an Apple TV, the LT1 is not only small and portable, but also easy to fit within existing enclosures thanks to its DIN-rail mounts. Connecting an SDI-12, NMEA and Tipping Bucket Rain Gauge sensor is simple and straightforward, and completing the setup can be done either locally or offsite, through Bluetooth or the LT1’s web-based configuration software.


The unit is fully GOES or cellular-capable, and takes up next to no space within enclosures. Efficient and thoughtfully designed, the LT1 delivers rock-solid telemetry with no compromises.

Manage your data with the included FTS360 web-based software. Powerful and easy-to-use, FTS360 allows you to view, organize and control your stations and sensors from your computer or mobile device. Using the Internet of Things (IoT), the software provides a secure and reliable way to create an intelligent network of sites that makes it easy to get the data you need, when you need it.
