Semtech Corp. has launched a network in Ventura County to wirelessly track groundwater pumping from the Fox Canyon aquifer. The Camarillo company has partnered with Mueller Systems LLC, in Middleboro, Mass., and Senet Inc., in Hudson, N.H., on the network for the Fox Canyon Groundwater Management Agency. Semtech will provide the radio frequency technology that synchronizes smart devices wirelessly without a cellular network. Senet will deploy the network while Mueller supplies the meters to track groundwater pumping. “By providing sustainable and efficient infrastructure, we hope to support California’s water conservation goals,” Semtech Chief Executive Mohan Maheswaran said in a prepared statement. The companies want the network to serve as a model for what can be used elsewhere in California and the U.S. to track groundwater useage. The Fox Canyon agency’s boundaries extend from the coast at Oxnard and Port Hueneme toward Camarillo and Moorpark and areas adjacent to Simi Valley and south of Santa Paula. Semtech shares closed up 28 cents, or less than 2 percent, to $16.82 on the Nasdaq.
