Gemini Data Loggers

Gemini has been manufacturing the Tinytag range of data loggers in the UK since 1992. Tinytags are used for cost-effective building monitoring, primarily to record temperature, humidity, carbon dioxide and single and three phase power usage. Data from the battery powered loggers is downloaded to a PC via a USB connection and viewed with easy to use Tinytag Explorer software.

Tinytags are ideal for indoor monitoring where flexibility, size and the lack of wiring are important. They may be used for short periods to trouble-shoot conditions in a particular area, or remain in place for longer periods in multiple locations to build up profiles. If required, data from loggers monitoring different environmental parameters may be combined to present an integrated picture of overall building performance.

Tinytags are used in all kinds of domestic buildings, offices, schools, warehouses and industrial premises, typically to:

  • Record environmental conditions to comply with H&S regulations
  • Ensure the comfort and well-being of occupants
  • Monitor the effects of different types of building materials, e.g. loft or wall insulation
  • To validate heating, ventilation and air-conditioning systems
  • Monitor conditions for temperature sensitive goods in storage

The Tinytag carbon dioxide data logger is designed specifically to help monitor indoor air quality, helping to verify that ventilation systems are performing correctly, and preventing a CO2 build-up which can cause reduced concentration levels in occupants and in some cases can lead to health problems.

The Tinytag Energy Logger is designed for use in power-hungry premises to monitor single and three phase power usage. It can be used for spot-checks or for longer term recording and is ideal for monitoring energy consumption in line with ESOS, ISO 50001, and other energy management requirements. The Energy Logger can be used to monitor individual equipment, to help build consumption profiles, monitor electrical distribution and provide sub-metering information.

In larger buildings, those with multiple monitoring points, and applications where it is preferable to view current rather than historic data, the Tinytag Radio Data Logging system is an ideal solution. The system uses wireless communications to send 'real-time' data automatically to a receiver connected to a PC for immediate viewing.
