  • Standard application: 4-channel data logger
  • Can be customised to individual requirements via studio


Flexible energy supply

The devices of the myDatalogEASY IoT series have a modular concept for power supply. Adapt the supply to the conditions on site and choose flexibly between battery, rechargeable battery and direct supply. The serial number-managed supply units (PSU) facilitate traceability.

IoT autarchic - myDatalogEASY IoT

Integrated sensor supply

Three switchable sensor supplies (from 0.1 second) are available for supplying sensors. A switchable sensor supply which can be adjusted in the range of 5-24V by means of software and two 3.3V.

MPP: Optimized charging power

With the help of an MPP (Maximum Power Point) tracker, the device can independently determine the ideal operating point of the PV module, regardless of the size of the solar panel used. Taking into account the environmental influences (clouds, shading, temperature, ...), the optimum charging power is always achieved.

Modbus RS485 & temperature measurement

For the implementation of devices and machines, the myDatalogEASY IoT offers communication via RS485 interface. Another optional feature is the external temperature sensor PT100/1000.

Flexible supply options with the PSUs

By using the intelligent power supply units PSUs (Power Supply Unit), the following supply variants are possible:

  • Direct operation on a PV panel for autonomous operation
  • Use of primary batteries with a service life of several years
  • Supply on 12V or 24V on-board networks
  • Operation on supply networks that only carry electricity temporarily such as street lamps
  • Supply to mains voltage with power failure message

The PSUs have a unique serial number, an identifier of the PSU type and a charge quantity counter that is retained even when the PSU unit is exchanged for another unit.

Autarkic outdoor operation

For applications without existing infrastructure in the open field, the myDatalogEASY IoT with the outdoor mounting box is the perfect choice.

The 30W solar panel is supplied with a pole mounting bracket for poles from 60 to 300mm. The panel provides the power for autonomous operation of two 4-20 mA / 15V probes, which operate with a measurement interval of 1 minute and require 20 seconds warm-up time.

With the outdoor mounting box (340x200x150mm), the myDatalogEASY IoT is mounted on the poles. A vandal-proof multi-band antenna is already integrated in the box. The outdoor mounting box is also UV-resistant.


Microtronics Modbus Master Library

The Modbus master library currently supports the master mode for serial interfaces (RS232 and RS485) and is characterised by its universal applicability. In addition, great importance was attached to easy integration into own projects during the development. However, the complete source code is also available in the Studio. The data transmission can optionally be in the more efficient Modbus-RTU or alternatively in Modbus-ASCII format. You can find out more here.

Recommended tariff

With the runtime calculator you can estimate the autonomous runtime of the application as well as the costs incurred. The actual costs and energy consumption depend on the measurement conditions, such as the reception quality and ambient temperature. Detailed information on the tariffs can be found here.
