Not always. In fact, most smart controllers simply suspend irrigation when it rains, without accurately measuring rainfall. By comparison, the ESP-SMTe not only suspends irrigation, it measures instantaneous rainfall amounts, determines the effective rainfall and calculates exactly how much to adjust your watering schedule to prevent over-watering and under-watering.\u003c\/p\u003e\r\n\u003ch4\u003eThe proven accuracy of weather-based scheduling\u003c\/h4\u003e\r\n\u003cp\u003eIn designing the ESP-SMTe, we've simply reduced the cost and complexity of the weather-based control systems we began pioneering for golf courses over 25 years ago.

That's why the ESP-SMTe customizes each zone's irrigation schedule. It factors in location, soil type, landscape slope, plant type\/density, sun exposure, sprinkler type and root-depth requirements. Based on this zone-specific data, the ESP-SMTe controller optimizes the irrigation schedule to promote lush, healthy plant material in each part of your yard, while substantially reducing water waste and runoff.\u003c\/p\u003e\r\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\r\n\u003cdiv style=\"display: block;\" id=\"p7tpc1_4\"\u003e\r\n\u003ch4\u003eDimensions\u003c\/h4\u003e\r\n\u003cblockquote\u003e\r\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eController\u003c\/span\u003e\u003c\/p\u003e\r\n\u003c\/blockquote\u003e\r\n\u003cul\u003e\r\n\u003cul type=\"disc\"\u003e\r\n\u003cli\u003eWidth: 10.7\"\u003c\/li\u003e\r\n\u003cli\u003eHeight: 7.7\"\u003c\/li\u003e\r\n\u003cli\u003eDepth: 4.4\"\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/ul\u003e\r\n\u003cblockquote\u003e\r\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eSensor (Largest Area Across)\u003c\/span\u003e\u003c\/p\u003e\r\n\u003c\/blockquote\u003e\r\n\u003cul\u003e\r\n\u003cul type=\"disc\"\u003e\r\n\u003cli\u003eWidth: 6.0\"\u003c\/li\u003e\r\n\u003cli\u003eLength: 8.8\"\u003c\/li\u003e\r\n\u003cli\u003eHeight: 5.9\" (includes Solar Shield)\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/ul\u003e\r\n\u003cblockquote\u003e\r\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eMounting Bracket (Mounted on Vertical Surface)\u003c\/span\u003e\u003c\/p\u003e\r\n\u003c\/blockquote\u003e\r\n\u003cul\u003e\r\n\u003cul type=\"disc\"\u003e\r\n\u003cli\u003eMaximum reach: 7.0\"\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/ul\u003e\r\n\u003ch4\u003eElectrical Specifications\u003c\/h4\u003e\r\n\u003cul\u003e\r\n\u003cul type=\"disc\"\u003e\r\n\u003cli\u003eInput Required: 120VAC +\/- 10%\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cul type=\"disc\"\u003e\r\n\u003cli\u003eOutput: 25.5VAC 1A\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cul type=\"disc\"\u003e\r\n\u003cli\u003eSurge Protection: Primary input side has (2) built-in MOV's (metal oxide varistor) to protect circuitry.
