Hunter's Irrigation Management & Monitoring Software (IMMS) is a PC-based software package that makes central control of large-scale irrigation systems affordable, usable, and comprehensible. IMMS software and hardware have been intensively developed and refined into a graphically based irrigation command and control program. With IMMS, interactive map graphics (to station level) put the irrigation system manager in complete visual control of wide-area watering operations. An optional ET software add-on provides complete weather-based irrigation with station level soil moisture modeling, using inexpensive local ET sensors. IMMS has a full range of communications options, including Ethernet, GPRS mobile, dial-up telephone, UHF radio, and hardwired cable. IMMS is a PC-based application that is compatible with Windows XP through Windows 8.
