Apparatus, systems and methods for irrigating lands

An irrigation system for irrigating a plurality of pieces of land, comprising:

• a plurality of gates each of which is configured to adjust a water flow for irrigating a respective one of the plurality of pieces of land, which is a farm that includes a plurality of areas connected with a water channel, wherein the water channel has a water flow that is adjustable by a corresponding one of the plurality of gates;
• a plurality of control units each of which is configured to control a respective one of the plurality of gates to adjust the water flow based on environmental information related to the plurality of pieces of land, wherein each of the plurality of control units is a microcontroller unit (MCU) comprising at least one sensor contained within the MCU, and wherein each of the at least one sensors comprises a respective laser sensor configured to detect a respective degree of openness of the respective one of the plurality of gates;
• a plurality of water level gauges each of which is configured to measure a water level of a respective one of the plurality of areas;
• and
• a plurality of water valves each of which is configured to irrigate a respective one of the plurality of areas using water from the water channel based on the water level,
• wherein at least one of the plurality of water level gauges has a surface aligner configured to detect a surface level of the Earth in the respective one of the plurality of areas, wherein the water level of the respective one of the plurality of areas is measured based on the surface level.
