Customer

Softeq delivered a set of standalone temperature and humidity data loggers equipped with sensors with extended temperature measuring range.

The solution utilized hardware and software components for aggregating, processing, and storing information retrieved from the humidity and temperature data loggers installed in a laboratory. The devices are built as one-channel and six-channel instruments that automate data collection and its submission to the server-based register.

  • Business name Chrometrix Systems
  • Location Canada
  • Business Activity Laboratory equipment supplier

Problem

The customer was already tapping the Softeq software implementation skills for building a comprehensive data acquisition and management system. The solution had to utilize hardware and software components for aggregating, processing, and storing information retrieved from the humidity and temperature data loggers installed in a laboratory.

Softeq was employed to create a set of standalone temperature and humidity data loggers equipped with ultralow temperature measuring sensors and a custom Android app to work with collected data.

Solution

The devices are built as one-channel and six-channel instruments that automate data collection and its submission to the server-based register.

Temperature Sensor

  • Has an extended temperature measuring range — from -200 to +120 °C 

One-channel Data Logger

  • Automatically measures temperature at a given time interval and with a designated precision
  • Stores up to 4,000 records in nonvolatile memory
  • Outputs data to an e-Ink display

Six-channel Data Logger

  • Automatically measures temperature at a given time interval and with a designated precision using 6 sensors
  • Stores up to 4,000 records per sensor in nonvolatile memory
  • Automatically transmits collected data to the server over HTTP
  • Displays temperature fluctuation chart
  • Sends alerts upon exceeding the set threshold temperature
  • Connects to LAN via Ethernet or Wi-Fi
  • Supports PoE
  • Is equipped with a web interface for administering the device

Android App

  • Works with data acquired from the data logger via Bluetooth Low Energy or USB
  • Is designed to retrieve data from custom-made sensors, as well as 3rd party sensors such as DS1921, DS1922
  • Transfers acquired data to the server
  • Programs sensors
  • Outputs retrieved data in the form of a table or a chart

Results

The resulting solution is a multiunit and functionally rich custom alternative to the generic choice of similar temperature and humidity instruments.
