390  be PVM

The ultimate tool for the modern farmer: the Wireless Sensor Spear is a GSM-enabled spear that accurately monitors temperature and moisture of stored crops. Each spear displays its own data on the AgroLog App and it can be moved around by farmers wherever it may be needed most.


A new powerful device

An innovative grain spear, with cellular technology, collects moisture and temperature data using wireless technology to provide real-time insights.

Suitable for different crops

The spear works with many types of crops and in diverse environments. It can be placed, for example, among barley, grain, potatoes, peat, and woodchips.

Multiple places, one app

The AgroLog App displays data collected from multiple spears placed in different locations and sends notifications whenever critical thresholds are reached, preventing grain loss and reducing risks.

Portable Monitoring System

You can place the probe everywhere and you can move it around your farm easily. Once the grain probe is positioned it collects data that is displayed in the app. The device will automatically update the data every hour, but if you want an instant measurement you can press the central button.

A big advantage of our grain probe is that no matter where you are, you are always in control of your farm and crops through your smartphone. Moreover, our AgroLog App gives continuous monitoring to ensure quality and risk prevention.
