AKS capacitive soil moisture and temperature probe, sold individually. Available in 4 lengths (30 to 120 cm), it measures at 3 to 9 depths depending on the model. Supplied with a 2 m cable featuring a T-connector for daisy-chaining to an existing AKS 4G connected unit. One unit supports up to 3 probes in series. Compatible with AKS 4G connected units.
- Requires an Akua Hub subscription — €10 excl. VAT/month including 5 probes, no commitment, 1st month free. No subscription required at purchase. View details →
Extend your measurement network
You already have an AKS 4G gateway and want to multiply your measurement points? A gateway accepts up to 3 probes connected in series — each additional probe covers a new zone, a new plot, or a new soil type, without investing in a second gateway.
The AKS standalone probe is delivered with everything needed for daisy-chaining: a 2 m cable with T-connector, ready to plug into your existing installation.
Don’t have a gateway yet? Start with the complete AKS kit (probe + 4G gateway) — the recommended entry point for a first installation.
What you measure
- Volumetric soil moisture across 3, 5, 7 or 9 depth levels (depending on model)
- Soil temperature at the same depths
- Data transmitted every hour to the Akua Hub platform via the AKS 4G gateway
Accuracy: ±1.5% moisture — ±0.5°C temperature.
The 4 available models
| Size | SKU | Depths measured | Price excl. VAT | Recommended use |
|---|---|---|---|---|
| 30 cm | AKS-MP-30 | 3 levels | €85 | Shallow-rooting crops |
| 60 cm | AKS-MP-60 | 5 levels | €115 | Vegetable crops |
| 90 cm | AKS-MP-90 | 7 levels | €155 | Arable crops |
| 120 cm | AKS-MP-120 | 9 levels | €215 | Viticulture, arboriculture |
A guide to typical root depths is available to help you choose.
Up to 3 probes on 1 gateway
Each probe is delivered with a 2 m cable fitted with a T-connector, enabling multiple probes to be daisy-chained onto a single AKS 4G gateway. The T-connector maintains continuity in the chain: the probe joins the circuit without interrupting the connection to the others.
| Gateways | Probes | Example configuration |
|---|---|---|
| 1 | 1 | Starting complete AKS kit |
| 1 | 2 | Complete kit + 1 standalone probe |
| 1 | 3 | Complete kit + 2 standalone probes (maximum) |
You can mix different probe lengths on the same gateway — an aks-60 for your vegetable plot and an aks-90 for your arable crops, for example.

Akua Hub subscription
Access to data and the Akua Hub platform requires a monthly subscription:
- €10 excl. VAT/month — 5 probes included
- +€2 excl. VAT/month per additional probe beyond 5
- 1st month free — no commitment, cancel any time
- SIM card and 4G data plan included — no extra operator costs
The subscription can be canceled at any time, with no fees or notice. There is nothing to subscribe to at the time of purchase — subscription is completed after receiving your equipment, when registering your probes on Akua Hub.
The first month of subscription is free. In practical terms, this means that during your 30-day satisfaction guarantee period, you pay nothing — neither for the hardware if you return the probe, nor for the subscription if you decide not to continue. Monthly billing only starts after this period.
What you need to get started
The standalone probe requires an AKS 4G gateway to operate. If you don’t already have one:
First installation? Start with the complete AKS kit — probe + autonomous 4G gateway, from €135 excl. VAT. It’s the simplest way to get started.
If you want to position your gateway at height (better solar exposure, better network coverage), the remote mounting kit is available as an option.
