Aclima designs and deploys distributed sensor networks that enable a higher level of environmental awareness. The firm manufactures precise and stable soil moisture sensors used for research and for SMART irrigation control systems. The Closed Loop Irrigation® systems operate by real-time soil moisture content as measured by Acclimaâs patented Digital TDT® and Digital TDR® soil moisture sensors. Scott Anderson, Acclima's founder and Chairman, developed Acclima's revolutionary sensor after his retirement as an electrical engineer for Hewlett Packard. Dissatisfied with the state of irrigation control. where timers wasted water and soil moisture sensor technologies on the market provided only relative and unstable information due to changing soil temperature, chemistry and compaction, Scott overcame the problems by digitizing a time domain transmission signal and patented the process. Acclima brings Closed Loop Irrigation® control to provide healthy turf and crops while saving water, fertilizer and frustra
