1. An irrigation system, comprising:
a gate configured to adjust a water flow for irrigating a farm that includes at least one area 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 comprises at least one laser sensor contained within the control unit, wherein the control unit is a microcontroller unit (MCU), and wherein the at least one laser sensor is configured to detect a degree of openness of the gate;
at least one water level gauge configured to measure a water level of a respective one of the at least one area; and
at least one water valve configured to irrigate a respective one of the at least one area 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 laser sensor.
