Apparatus, systems and methods for irrigating lands

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

• at least one gate configured to adjust a water flow for irrigating at least one area of land connected with a water channel, wherein the water channel has a water flow that is adjustable by of the at least one gate;
• at least one control unit configured to control a respective one of the at least one gate to adjust the water flow based on environmental information related to the at least one area of land, wherein each of the at least one control unit 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 at least one gate;
• at least one water level gauge configured to measure a water level of a respective one of the at least one area of land;
• and
• at least one water valve configured to irrigate a respective one of the at least one area of land using water from the water channel based on the water level,
• wherein the at least one water level gauge has a surface aligner configured to detect a surface level of earth in the respective one of the at least one area of land, wherein the water level of the respective one of the at least one area of land is measured based on the surface level,
• wherein the environmental information comprises the water level and the at least on control unit controls the at least one gate to adjust the water flow based on the environmental information and the respective degrees of openness of the at least one gate detected by the at least one sensor.

An irrigation system, comprising:

• a gate configured to adjust a water flow for irrigating 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 the gate;
• a control unit configured to control the gate to adjust the water flow based on environmental information related to the farm, wherein the control unit is a microcontroller unit (MCU) comprising at least one sensor contained within the MCU, and wherein the at least one sensor comprises a laser sensor configured to detect a degree of openness of the gate;
• 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;
• a solar panel;
• a battery charged with energy from the solar panel to provide energy to a motor;
• 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 the environmental information comprises the water level and the control unit controls the gate to adjust the water flow based on the environmental information and the degree of openness of the gate detected by the at least one sensor.
