revolutionizing agriculture

Better tech.
Better crops.

Acclima helps the research, agriculture, and greenhouse industries maximize efficiency and boost production through breakthrough true time-domain reflectometer (TDR) soil water content sensors (a.k.a. soil moisture sensors and soil moisture probes), SDI-12 data loggers, and cloud-connected solar nodes and gateways.

Superior accuracy, superior cost

“True time domain [soil moisture sensors] have been very expensive in the past, which is why they have not been much used other than in agricultural and environmental science. The relatively inexpensive ($100’s) sensors that were purported to be TDR sensors in the past, were not true time domain sensors. New, relatively inexpensive true time domain sensors are now available in the market (Acclima TDR-315 and ACC-TDT).” – Steve Evett, U.S. Department of Agriculture

Our Story

Building the best soil moisture tech since 2001

After 30 years at a Fortune 500 company, Scott Anderson stepped down from his executive position to launch Acclima, pursuing a longtime vision to engineer practical ways for precision irrigation control. Today, he holds numerous patents for digital TDR soil water content probes and SDI-12 data loggers.
