Soil-moisture-tester

A soil moisture prototype

Soil moisture project/ sensor measures the volumetric water content in soil.

Objective

This project is to help farmers and households to keep track of their moisture content of the soil in their farms and kitchen garden respectively within the Refugee camps.

Features of the project

Works with a battery (7v) and solar panels

Digital counter of :-

  3 displays “Low /dry moisture level 
  
  6 displays “ Moderate moisture level 
  
  9 displays “ High moisture level

3. Buzzer for sound – This Bips when there is high moisture level

4. Light weight.

Expected Improvements

• Casing

Adjustments in accuracy

Soldering components on soldering Board.

Images.

The three stages of the soil moisture level.

*DRY

Mid - Moistured

Most - Moistured
