A typical use case – food and cold chain monitoring

Our Tempo Disc™ range of Bluetooth® Low Energy sensors and data loggers can be used in a wide variety of business and home applications.  One of the most popular use cases involves temperature monitoring.  Here is a short video on how a Tempo Disc™ temperature and humidity sensor and data logger can be used in a catering business, by way of example.

The Blue Maestro difference

Our products

We manufacture a range of Bluetooth sensor and logger products to sense your world.  From a high precision Bluetooth sensor and logger used for the transportation of pharmaceuticals through to consumer mini weather stations and baby monitors, Blue Maestro has a Bluetooth sensor and logger for you.

Our difference

We aren’t resellers of third party sensors and beacons made cheaply to the detriment of range, battery life and features.  We design, develop and manufacture our own Bluetooth sensor and logger devices to be the best. When you deal with Blue Maestro you are dealing with the team that designed and made the Bluetooth sensor and logger.  It’s our level of expertise, capability and attention to detail that makes us different and our sensor and logger products superior.

We customise

We are experts in providing custom Bluetooth sensor and logger solutions based on our proven technology and designs.  We have done Bluetooth sensor and logger projects for the NHS, Zebra Technologies, Laird Technologies and others.  Our approach accelerates development, is cost effective and results in a higher quality sensor and logger product for you and your end users.  When you need a sensor and logger to work well, is delivered on time and on budget, drop us a line.

Superior technology

Our Bluetooth sensor and loggers are made to the highest quality using the best components.  All of our antennas are omni-directional ceramic chip with design input and tuning done from our partners at Nordic Semiconductor and Johannson.  We utilise the latest in Nordic Semiconductor, ARM Cortex M4 and Johannson components.  We go to great lengths to maximise range, energy efficiency and sensor accuracy making our products world leaders in Bluetooth sensor and logger technology.

Great sensor design and superior performance
