Sensors

  • Real-Time Clock: max. 20ppm at 25°C

  • Temperature**: -10 ºC - 70 ºC ± 1 ºC

  • Humidity**: 5% - 95% RH ± 5% (long settling times for larger change)

  • Barometer**: 260 to 1260 hPa ± 1hPa

  • Accelerometer**: 3 - axis

  • Internal light sensor**: approx. 0,2 Lux and above

Info

** optional sensor equipment

Interfaces

  • 4 I/O Ports (on request)

Data transfer protocols

  • HTTPS

Data storage and processing

  • Messages that cannot be sent immediately are stored temporarily on the device. The reserved storage space is 25kB, which is sufficient for approximately twenty messages.

  • The device can collect a maximum of 10 consecutive messages in memory before they need be to sent or flushed to flash memory. Additional messages are discarded if the memory space is exhausted and the device has not finished sending or flushing the messages that are already in memory.

Security Features

  • Protected Device Memory

  • Secure communication via transport level security (TLS)

  • Device authentication via ECDSA signatures

Indicator / Buttons

  • 3 multicolor LEDs (one for charging detection)

  • 2 Buttons

Electrical data

  • Power Supply via USB-C

  • USB C Specification

    • Voltage : 5V

    • Current: 3A

Battery options

  • Rechargeable LiPo battery (3.7V, 2.750 mAh)

    • 300 recharging cycles

    • The device can collect 2000 data points per battery charge in typical scenarios.

  • 3 AA batteries ENERGIZER L91

    • Enables the device to operate in more extreme temperature conditions than the LiPo variant. See “Working und Storage Conditions”

    • The device can collect 2600 data points with one set of batteries in typical scenarios.

Info

The exact number of data points per battery charge heavily depends on device as well as environmental paramenters such as measurement frequency of different sensors and GNSS, connectivity, temperature, etc.
