Arduino Wood Moisture Meter

The project soil moisture meter using arduino uses arduino board a 16 2 lcd module and soil moisture sensor in order to display the humidity moisture of soil.

Arduino wood moisture meter.

Whatever moisture meter arduino styles you want can be easily bought here. The working principle and circuit description is very simple that anymore can understand who have little knowledge of arduino board. Insert the probes of the sensor head into the soil to determine its moisture content and carefully adjust the preset vr1 so that voltage just above 3v is available at pin a1 of arduino board1 if the soil is wet enough. A humidity sensor used to detect the moisture in air could be used if you have a closed environment for your honey.

Arduino should have no problems measuring 100megohm resistances that way. In order to know the moisture of soil at different stage. This project is very useful for farmer floriculture researchers etc. All you need is a multimeter capable of measuring 10 megaohms higher is better.

An electrical current will be passed from one pin to the other and the meter will give you a reading based on the resistance to the current. It endeavors to provide the products that you want offering the best bang for your buck. In most cases using these meters is remarkably simple. Not measuring the moisture content in a piece of wood can come back to haunt you down the line after an established piece of woodwork begins to deteriorate.

A pinless meter has a sensor plate that s held against the surface of the wood. These electronic devices use electromagnetic fields to measure the moisture in wood without having to do any damage to the wood whatsoever. According to wagner meters the acceptable moisture level for wood objects used indoors is generally 6 to 8 for wood flooring 6 to 9 furniture and 9 to 14 for construction. The two nail probe used for soil moisture or wood moisture is a possibility but the base resistance would need to be known.

The ideal moisture content for wood depends on the wood and its function. Try a 10 20megohm pullup resistor and a 100n film cap low leakage to ground. Screenshot of arduino ide. External probes driven to the center of a board allow you to get a core reading in stock that s too thick for the pins built into the meter the probes can also be left in a.

External probes extend the reach of your meter. Say inside of the hive do you need an instant more or less you would need to use a refractometer. A few brad type nails and a template with holes 1 25 inches apart. Component layout of the pcb.

The plate projects an electrical field into the wood the meter can sense changes in the field caused by moisture and wood the meter then converts the change to a moisture content reading. Both connected to an analogue input. This instructable will show you how to measure the moisture content of your wood and come to a decision as to whether your wood is burnable safely in your stove.
