intéressant

Ma première sonde avait un problème de connexion au niveau de la prise jack , la seconde se comporte avec satisfaction .la réactivité de la mesure est compensée par une indication légèrement inférieure de la consigne ; en attendant une mise à jour logiciel et une bonne étanchéité de la connexion avec le prolongateur de 5 mètres.
Les indications sont fidèles et bonne finition du produit

Update

Continuing on my previous review I did some trials with water/salt/mud mixture and eventually the sensor indicated 74%. I expected a full 100% but it improved. I use the reading in Home Assistant and I can calibrated it there (range 0-74% will become 0-100%). Now in the soil next to the plant it read 27% which is a fair value for moist soil as far as I know.

Measurement accuracy

Inside a damped cloth it only shows 44% humidity. Outside it shows 0%. It should have a way to calibrate it.

Sorry for the inconvenience, our customer service team will contact you to help you solve this issue.

Doubtful performance

Just bought a number of ms01 soil moisture sensors.

Some remarks.
First it comes with a rather short cable. For in house that could be ok. Outdoors it will not work because it’s not likely to have your TH10/16 installed on 30 cm from your measuring point. You can extend the cable up to 10m with extension cables but I am worried about the waterproof connections of those using them outdoors.
Secondly the 0-100% scale doesn’t work. I don’t think they have calibrated it very well. Full dry is 0%. That’s at least something. Fully wet should be 100% but in a glass of water it only gives 46% in my case or at best in fully soaked soil 25%. So to use it as a irrigation switch you need to find the switch point between 0-25%. I am curious what bias it will have otherwise it will just not function properly.

Sorry for the inconvenience, our customer service team will contact you to help you solve this issue.

Dissaponinting

After seeing the videos i was sure that i can control the pump only by the reading of soil moisture. In reality it is just an indication which most of the times is not accurate. Sometimes even on already irrigated soil the reading is stuck at 39%. I've cleaned it, reinstalled it in multiple points but always this inaccurate reading.
