The invention relates to the technical field of electronics, in particular to a solar direct current motor water pump allowing remote measure and control of soil humidity. The water pump comprises a soil humidity sensor, a wireless transmitter, a water source detection sensor, a water source optical coupler control switch, a wireless receiver and a direct current motor water pump. The solar power supply water pump allowing remote wireless measure and control of soil humidity facilitates full automatic control irrigation in the crop field where no altering current power supply can be used, especially in the crop field away from a water source, insufficient in water source and with uneven terrain, enables different crops to be in the optimum growth state, and greatly improves the agriculture planting production level. The soil humidity sensor and the water source detection sensor adopt electrode sine wave sensing, and effectively prevent electrolytic etching and prolong service life. The water pump has the advantages of wireless receiving / transmitting crystal oscillators, high stable frequency remote measure and control, pulse coding, high coding capacity, high anti-interference and stable reliable operation in adjacent crop fields without interference. The water pump is widely applied to crop field irrigation to ensure that soil humidity can meet the crop growth requirement.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a solar energy telemetering and remote control soil humidity DC motor water pump. Background technique [0002] The soil where plants grow needs to maintain a certain humidity. Manually controlling soil humidity is not accurate and requires a lot of labor, which is not suitable for modern agricultural production requirements. In particular, it is inconvenient to lay AC power grids in arid and poor areas with scarce rainwater, insufficient water sources or far away from water sources, or uneven terrain, which affects farmland irrigation. Contents of the invention [0003] The purpose of the present invention is to provide a farmland where the AC power grid is inconvenient to lay, measure the soil moisture and dryness information wirelessly, transmit the electromagnetic wave space to the wireless receiver with the water source to set the irrigation humidity and water supply r...
