Bambach – Remote wireless monitoring

FFF – Field Humidity Wireless

FFF – Field Humidity Wireless


Using the FFF, measurement data – preferably moisture and temperature in the soil – that is recorded from remote and scattered areas can be transferred directly to your PC or smartphone for monitoring purposes. This system enables the recording of real-time measurement data and monitoring with the help of a web-based dashboard. Thus, it is ideal for managing both urban facilities and farming operations. The wireless unit itself works with a very long-lasting battery and is waterproof. As such, it can be installed under the floor together with the sensors and is thus protected against vandalism. A special feature is the option to connect several different sensors to one wireless unit. Remote-controlled irrigation can be implemented using further components. The system set up (installation) is simple. It only consists of connecting the sensors to the wireless unit and inserting the battery.
The dashboard of the Holfuy web service provides a clear user interface for easily viewing the sent measurement data. Measuring intervals can be easily changed, automatic notifications can be set and solenoid valves can be switched at the click of a mouse.

We would be happy to advise you on the best combination of wireless units and sensors for your projects and applications.

Classic plug-in tensiometer

A tensiometer is used to measure suction tension. The porous cell of the tensiometer uses capillary action to transport water outwards into the drier soil. A negative pressure is then created within the closed pipe. This negative... ...more Topseller
