WH31SM

Works GREAT until you run over it with the lawnmower. Then it doesn't work so well. Did this twice with two different sensors. Needs a feature that connects better with my brain to not run over it, twice.

This sensor was easy to add to my system. The test the instructions recommended showed the calibration was correct out of the box. I have no way to confirm its accuracy in the ground, but the readings seem reasonable. In any case, I believe it will help me determine how often I should water my avocados!

My unit works great, right out of the box. The base unit recognized the new sensor immediately and the calibration appears to be accurate, right out of the box. (I compared the reading to an old soil moisture meter I had lying around the house)

I have been enjoying my WS-2000 weather station for several years and love being able to get real-time data happening right in my own backyard. I recently discovered the soil sensors available as an accessory. This has been an great addition to my weather station and lets me monitor my vegetable garden and newly planted tree right from my kitchen to be sure both are being adequately watered. You can even set up text alerts to notify when levels drop to specified parameters.

Really like my WS-2000 weather station. I have four add-on temperature sensors for various rooms including garage and basement. All Great - use the Ambient Weather app to keep track of the house when I am away. Thought moisture sensors would be a great addition to guide the use of my wifi enable irrigation controller. I purchased two WH31SM - Wish I had read the reviews first. First one passed the calibration test but was VERY slow to respond to change from dry to wet (water emersion). It then took three days to return to a more normal dry reading when removed from the water. The second one failed the initial calibration (water emersion) test never getting above 40% after repeated dry-wet cycles Very disappointed and will return. I really wanted them to work!

Great sensor no connectivity issues. Accurate sensing well made especially with the probe housing. Only issue is a bit expensive and wish they have a additional separate screen monitor in addition to the ambient weather console so we can monitor all moisture sensors in one glance.

We have not had rain for a month and even after calibrating it, my gauge still reads 22%. When I water my garden it goes up to 35%, so I am not sure how accurate it is. Will keep experimenting with it, as the rest of the Ambient system works great and I am very happy with it.

Highly recommended this product for people who like to monitor the weather condition around their home. I currently am using this product for my garden to see how it reports in the winter and seems accurate except with the temperature dropping below freezing making it read dry but it’s frozen which is understandable. Would highly recommend to everyone with the WS-2000

Es un buen complemento para la estación meteorologica ws2000 De forma inmediata reconoció el sensor.

I bought three Ambient Weather soil sensors. One of them didn't work (ID: CE2F83). Can't trouble shoot.

Put in the battery, and worked right away! Thought I'd have to spend some time setting up with the central unit, didn't.

I use these with my weather station and app to monitor all our flower and vegetable gardens remotely! Love them! Not cheap but worth knowing the level of moisture everywhere!
