BMeasure-125i New Product 2019


The BMeasure-125i is an IOT data capturing and logging unit for real world data. The supplied BMeasure software toolset has been developed to enable units to be simple to configure and use. Both Linux® and Windows™ operating systems are supported. Operation as an MQTT client facilitates connection to industry standard IoT cloud platforms. Operating as a data logger, the system can autonomously sample and store the data to internal FLASH memory for later data retrieval.

Where there is a requirement to sample a larger number of channels, units can be linked to provide up to 32 synchronously sampled channels. This is ideal for many sensor array applications.

The unit is low power and has flexible power supply inputs. Battery operation can be used for remote monitoring applications. Typically these units are used in the laboratory, industrial and remote sensing areas.

Operational Modes

The unit has been developed to be extremely flexible, supporting a number of operating modes
  • Host Controlled
    Controlled via a host computer over any of the communication interfaces a user of program can instigate measurements and capture data from the system. The digital IO lines can be both read and written, the switch inputs read and the relays operated.
  • Autonomous
    In this mode the unit the unit has been programmed to make periodic measurements. These measurement can be saved on the unit for later retrieval or if network communication is available, data can be logged to a cloud based server.
  • Program
    In this mode the unit the unit runs a simple, user developed, Micro-Python script program. This extended form of Autonomous mode enables the unit to perform complex measurement sequences and perform simple actions based on the measurements. For example in a go/no-go indication when used in a testing application.
