A bulk-micromachined soil moisture probe with a mixed-signal interface

This paper presents a Multi-Chip-Module based (MCM) microsystem for irrigation management suitable for greenhouse environmental control. The proposed microsystem includes a soil moisture microsensor, analog interface and sigma-delta converter, and signal processing for digital filtering. A heat-puls...
