Question : Can you build a cheap Moisture meter for grain

Hello I'm a Peace Corps volunteer working with coffee. I'm helping farmers improve the quality of their coffee. To do this they need to dry their coffee very well. It is hard to tell if the coffee is dried enough without a moisture meter, and a moisture is very expensive. Does anyone know of how to build a moisture meter? this tells what percentage of the weight of the coffee bean is water, I believe. Or if anyone knows where to get one inexpensively, that would also help. Many thanks

using calcium chloride as humidity reducer closets /laundry rooms

I bought a product called "damp rid "in a hardware store that was used for removing moisture from hamper area,laundry rooms, to prevent mildew. i realized the pelted looked familiar and it was calcium chloride. i want to make my own as i have access to a big bag of calcium chloride. it looks like there is a piece of tyvek/ or other moisture passing membrane on one side of the top upper half, the other 3 sides of the bag look like a mylar  type bag.  The seams all seam to be sealed, except the top has a piece of plastic snapped-sea;ed over it, with a couple very small holes that go into the top half of the bag. the top plastic piece  also has a hanger  loop.. when i bought it the calcium chloride was in the top hang and the bottom half was empty. There looks like a plastic seam weld separating the calcium from the bottom half, and i noticed that are a couple 1/4 inch gaps in the seam. the calcium, chloride draws the moisture out of the air and turns it into water, which falls to the bottom half of the bag.pretty cool device, and seems i t would be able to make, if i can find a source for mylar or whatever this material is. i would also have to make the seams, not sure if glue would work, maybe make a clamp like device , rather than the welds, this way i could just empty the water and replace the calcium chloride, no reason to throw it out. anyone seen these devices, i noticed they have a www with the same name, they may have pictures.  Also looking for a source for mylar and tyvek.  I am not sure if the postal envelopes would work, i would also like to scrounge a sheet of tyvek to use as a ground-cloth or emergency shelter when out on my bicycle and the t storms hit. i haven't seen it except in big rolls, i guess i should keep a lookout for construction sites trash areas.otherwise i am not sure where  i could get a 10 ft piece. i will take the bag apart later to dissect the workings and see if i can measure the thickness of the  mylar

Question by tishza 9 years ago  |  last reply 9 years ago


I need an air moisture meter and possibly a thermometer in one.

Good day,I am trying to find a moisture and temperature meter (possibly in one). It will be a used in a beehive. During the winter the bees cluster together to keep warm. Warm air rises up and gets in contact with the cold ceiling. It cools off and releases moisture. The water then starts dripping down and creates a mess of wet bees and mold. Opening the hive during the winter is not recommended till temperatures get back over 40F. Proper ventilation is possible to achieve through the design of the beehive but i would like to know the level of moisture and temperature if i was to just walk next to the beehive. I have seen a few instructibles about moisture meters but they are geared more toward soil moisture. I need it for the air. The system could be powered by a rechargeable battery and a solar panel - i can take care of that myself. Thanks.

How would you build a moisture harvester?

Yes, the first thing nearly everyone remembers are the moisture farmers on Tatooine in Star Wars. Now, the question is, how would you go about building one? I was thinking about building a small hoop hut out of PVC but instead of of being a split cylinder, I was thinking of a donut shape of PVC covered with plastic. A center pan to catch water for harvesting the water or smaller holes in the drip pan itself for water delivery to the plants.

How can I make a grain moisture content sensor that can withstand high temperature?

We are working on a multi-grain dryer (controlled by Arduino Mega) that dries a corn to its required moisture content (mc). If the mc is near the required (ex. 12-14%), the dryer will stop automatically. We need to make a sensor that can withstand up to 140F while the drying is ongoing. Meaning, the sensor is inside the dryer reading mc every couple of hours. If there is any device, will the reading be affected by the heat? we are pretty low on budget now so we couldn't afford to buy any pricey device and I think its hard to ship to our country in terms of period since we are pretty much running out of time for our evaluation.

Cinderblock - To paint or not to paint

I always had this question in my mind.  Was the cinderblock designed to breathe?  In other words do we want the moisture to go from one side to the other in case of cinderblock walls (say in the basement walls?)  Logically, I would think that the answer is that we want to prevent the moisture to go from one side to the other.  If that is the case, why the cinderblock makers do not make waterproof cinderblocks by adding water proofing chemicals during the manufacturing process? I would greatly appreciate your insights on this subject.

Calcium Chloride Corrosive Effects

I know that calcium chloride can corrode metal, but does it require direct contact or can it generate fumes that could corrode?   Here's the issue:  I have a wood stove and I place a container of Damp Rid inside over the summer to absorb moisture.  It looks like the Damp Rid plastic container had a small crack, so moisture passed through the calcium chloride and through the container and through the back of the stove After a while I noticed a pool of water behind the stove.  I traced the problem back to the Damp Rid container, cleaned up the moisture inside and outside the stove, and replaced the Damp Rid.  At the same time I noticed areas all over the exterior of the stove where the finish was coming off, areas that were not in contact with the water.  In fact, at least one section of the stove that had direct contact shows no sign of  a problem. I'm trying to discover if the calcium chloride caused the problem, or if it's something else causing the damage.

Solar Capillary Irrigation

I was thinking: If you used a post hole digger and made 2' or 3' holes throughout the garden, then dropped an old pant leg or other scrap fabric down the hole, filled it up with soil while leaving some fabric exposed above the soil, covered the fabric with an inverted clear plastic or glass bowl, would this draw enough moisture through the fabric to irrigate the plants near the bowl? I'm thinking the sun would heat things up for condensation on the glass which would drip down the sides to the soil while capillary action would draw deep soil moisture through the fabric to the surface where garden plant root zones are. Anybody try this before?

"concrete smell"

Some 20 years ago, I built an addition onto my house. It is built on a concrete slab with 42 inch block foundation. I have a completely finished room in which I have installed ceramic tile flooring. Under the ceramic tile I used Ardex to level the concrete before tiling.  For the last 20 years I have never noticed what now appears to be a "wet mortar joint" smell. I have become increasing alarmed about the slab leaching moisture into the room. There is no visible sign of moisture. The tile is not exceptionally cold; it's just that smell.  Can anyone put my mind at rest, or suggest to me what this might be and how to remedy it. I definitely can not destroy the floor. Please advise. Thank you.
