sensecap / s2100

SenseCAP S2100 series

The S2100 family encodes different measurements depending on model and probe. The sample decoder is minimal; use Seeed / SenseCAP reference tables for production.

// SenseCAP S210X data logger family — highly firmware-dependent.
// This example decodes a minimal "measurement report" style frame; use SenseCAP console reference for production.
