Automatic controller for dry and humidity

The rapid development of agriculture has led to an increasing amount of water used in agriculture. However, China's water resources are severely lacking, and traditional agricultural irrigation methods have low water utilization rates, resulting in a significant waste of water resources. The development of water-saving irrigation is urgently needed. This article proposes a design scheme for a water-saving irrigation automatic control system, which has a relatively small investment and can achieve agricultural irrigation automation to a certain extent while utilizing water resources.
With the rapid development of agriculture in China, agricultural water consumption is increasing. However, China's water resources are severely lacking, and traditional agricultural irrigation methods have a water utilization rate of around 45%, resulting in a significant waste of water resources. Therefore, the current unreasonable traditional agricultural irrigation methods urgently need to be changed, and water-saving irrigation should be developed to save water resources. Water saving irrigation is a new irrigation mode that follows the objective law that crops have different water resource demands at different stages of growth and development, and carries out timely and appropriate irrigation to minimize the use of water resources and maximize crop output. This article proposes a design scheme for a water-saving irrigation automatic control system, which has a relatively small investment and can achieve agricultural irrigation automation to a certain extent while utilizing water resources.
JZ-41Automatic controller for dry and humidity， JZ-41 is a software/hardware upgrade based on 31; Software increases non-linear supplementation, stable filtering, and adds distributed I/O communication methods; Change the storage of ordinary EEPROM to ferroelectric memory FRAM in hardware; The ordinary non integrated isolated 485 interface chip is a Siemens RS485 interface chip; Change the interface method between the host and the probe; Eliminate faults caused by software and hardware failures, poor external contact, and vulnerability; 41 is a type suitable for measuring on-site functional requirements and high reliability requirementsAutomatic controller for dry and humidity.
