Arduino Wood Moisture Meter

A pinless meter has a sensor plate that s held against the surface of the wood.

Arduino wood moisture meter.

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. 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. Both connected to an analogue input. 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.

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 few brad type nails and a template with holes 1 25 inches apart. Whatever moisture meter arduino styles you want can be easily bought here. 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.

To use a pin type wood moisture meter simply insert the pins into the material you want to test and activate the meter. Say inside of the hive do you need an instant more or less you would need to use a refractometer. All you need is a multimeter capable of measuring 10 megaohms higher is better. These electronic devices use electromagnetic fields to measure the moisture in wood without having to do any damage to the wood whatsoever.

External probes extend the reach of your meter. Read dc panel meter using arduino. The two nail probe used for soil moisture or wood moisture is a possibility but the base resistance would need to be known. 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.

In order to know the moisture of soil at different stage. A humidity sensor used to detect the moisture in air could be used if you have a closed environment for your honey. 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. Arduino should have no problems measuring 100megohm resistances that way.

In most cases using these meters is remarkably simple. Screenshot of arduino ide. This project is very useful for farmer floriculture researchers etc. The working principle and circuit description is very simple that anymore can understand who have little knowledge of arduino board.

The ideal moisture content for wood depends on the wood and its function. Component layout of the pcb. Try a 10 20megohm pullup resistor and a 100n film cap low leakage to ground.
