AI Technical Summary

Technical Problem

When the substrate soil is short of water, it cannot be discovered in time, causing the plant roots to shrive or wither. The existing technology lacks an effective water shortage alarm system.

Method used

A soil matrix water shortage alarm system is designed, which includes a humidity sensor and a buzzer. Through the cooperation of internal and external pipe structures and a reset spring, the humidity sensor can be rotatably inserted into and removed from the soil matrix to avoid extrusion damage. The alarm is generated by combining battery power supply and single-chip microcomputer control.

Benefits of technology

It realizes real-time monitoring and timely alarm of substrate soil moisture, protects the sensor from damage, has a simple structure and low cost, is suitable for detection at various depths, and ensures the water supply needs of plants.
