Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

During calibration of the analog current sensor on several FCs (GEPRC / Matek / iFlight), I noticed a significant non-linearity when using the standard Betaflight model: Current [A] = (ADC[mV] * 10) / ...

Abstract: Hall current sensors suffer from severe measurement inaccuracies over wide temperature range due to sensitivity drift, offset variation, and nonlinear errors. To address these issues, GaAs ...

Abstract: An approach for online current sensing calibration is presented where an auxiliary switch and a precision sense resistor are connected in parallel with a main power switch to achieve ...

With increasing concerns about the global demand for energy and the overall expansion of environmental awareness, designers for power electronics applications are under constant pressure to improve ...

Geometric calibration is an essential process in remote sensing that ensures satellite imagery accurately represents the Earth’s surface. This procedure involves correcting spatial discrepancies that ...

THERE is no better way to ruin a perfectly good day than to make a mistake in the use of your air monitoring instrumentation. Industrial hygienists; military, industrial and public-sector hazmat teams ...

(MENAFN- EIN Presswire) EINPresswire/ -- In the world of precision measurement, the difference between reliable data and costly error often comes down to calibration ...
