Logging pressure and temperature on remote pipelines calls for a low-power, battery-operated device without continuous network access. NELSco built an STM32 logger that stores timestamped measurements for later analysis.
STM32 logging for 4–20 mA and temperature inputs; the tested configuration completed a seven-day autonomous run, with final runtime dependent on use conditions.
Timestamped data storage on an SD card with structured, Excel-compatible output, field-deployable without dependence on power or network infrastructure.
The Challenge
The device had to run for several days continuously in a remote desert environment with no infrastructure dependency; this meant engineering firmware and hardware for ultra-low power, accurately reading 4-20mA industrial sensors, and reliably storing timestamped data in a form that is easy to analyze later.
Our Approach
The STM32 system records 4–20 mA pressure-transmitter and temperature-sensor data. The tested configuration completed a seven-day autonomous run, with timestamped SD storage and Excel-compatible export. Final runtime depends on battery capacity, sampling rate, and environmental conditions.
The Result
The result was a battery-powered field logger for timestamped pressure and temperature records at sites without continuous power or network access.
Results
- Completed a seven-day autonomous run in the documented test configuration
- Timestamped pressure and temperature logging with Excel-compatible output
- Field deployment without power or network infrastructure dependency
