The project is intended to provide proper amount of irrigation to agricultural fields by observing the moisture content of soil. The project automates the process of manually irrigating the fields by switching the pump ON/OFF. It is implemented by using an 8051 series microcontroller, programmed such as to collect input signals that measures moisture content of soil through sensing arrangement. Sensing arrangement is made by inserting two stiff metallic rods into the field at some distance. An op-amp is used as a comparator that interfaces micr ....etc

digital soil moisture meter circuit pdf

The VG-METER-200 is a low cost hand held soil moisture meter with a professional digital display.

This a break through soil moisture meter is for professionals, but is in the price range that any home gardener afford it.

Not only does it provide accurate readings of soil moisture content it also displays the current ambient temperature, and has a light sensor which detects and displays the level of light.

This meter uses our break through VH400 soil moisture sensor, and presents soil mois ....etc

This generation introduced the Thumb 16-bit instruction set providing improved code density compared to previous designs. The most widely used ARM7 designs implement the ARMv4T architecture, but some implement ARMv3 or ARMv5TEJ. ARM7TDMI has 37 registers(31 GPR and 6 SPR). All these designs use a Von Neumann architecture, thus the few versions comprising a cache do not separate data and instruction caches. ....etc

soil moisture sensors interfacing with arm7 lpc2148

Soil moisture sensor

Soil moisture sensors measure the water content in soil. A soil moisture probe is made up of multiple soil moisture sensors.

This Soil Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help.Insert this module into the soil and then adjust the on-board potentiometer to adjust the sensitivity. The sensor would outputs logic HIGH/LOW when the moisture is higher/lower th ....etc
