Looking for commercial soil moisture sensors, to be deployed 1 meter below ground

Dear LoRaWAN-fellows,

For a customer project, I am searching for soil moisture sensors that should be deployed 1m below the ground. The output unit should be volumetric water content if possible. Could you please recommend me some sensors or get back to me if you are a manufacturer?

Thank you!

For approval i have installed a Dragino LSE01 as commercial variant os a asoil moisture probe.
Upto now it is only installed on ground level but it is also possible to burrie the probe under ground.

1.3 Specification

Measure Volume: Base on the centra pin of the probe, a cylinder with 7cm diameter and
10cm height.
Parameter Soil Moisture Soil Conductivity Soil Temperature
Range 0-100.00% 0-20000uS/cm

Sorry for the bad format. I did not find a good way to format the table right.
You can find the Specs in this Manual below:

With regards

Thank you engelking! I’ve come across this sensor while googling. It is nice to hear that you made a good experience with it.

Do you know of any waterproof lora modules? I can also plug a sensor to it and program the module.

There are quite a lot!
Have a look at the marketplace:
https://www.thethingsnetwork.org/marketplace/products/devices

As none commercial user some of the provided solutions are not available or affordable for me.
Nevertheless, the base of the LSE01 is also sold without a specific sensor as LSN50 “v2”

Something similar with a little bit more userfriendly configuration method is available from elsys.se
with the ELT series nodes. These sensors can be configured with NFC and a mobile App.

But there are so much more similar products availabel an even more good DIY Solutions.

Thank you a lot guys for the helpful and relevant replies!

Have a look at these as well.

This thread is quite old, but garden season has started here and so this topic may attract attention again. I came across a quite nice Dragino LoRa device with RS-485 interface included. It is capable of Modbus as well and therefore professional soil moisture sensors can be attached. Here you will find an example using the SMT100 (in German, but some screenshots and AT commands, so should be easy to follow). The SMT100 is absolutely waterproof and survices underground for years.
