View live colour-coded grain temperature updates from the crop store, identify areas needing further cooling or drying and select the fans required. Temperature and humidity readings are sent continuously to the user’s webpage, allowing data downloads to suit quality assurance needs. Data is backed up on the Microsoft cloud network.

Store management can be carried out on-line – moving equipment such as temperature sensors and ventilation fans to new positions and adding or removing them as the store is filled or emptied.

Barn Owl Wireless Automatic Fan Control

Martin Lishman Barn owl Wireless automatic crop monitoring and control system fan controllers
A wide range of equipment can be controlled automatically by Barn Owl Wireless. Controllers can be static for connection to an existing control panel, or portable to move with equipment between ventilation ducts. Versions for up to 12 single or 3 phase fans can be supplied.
Martin Lishman Barn owl Wireless automatic crop monitoring and control system control page
Controllers are configured remotely from the user’s Barn Owl Wireless webpage, with the option to allocate each fan independently to a different control programme including temperature differential, thermo-humidistat and drying.
Barn Owl Wireless automatic fan control reduces crop cooling time and maintains quality. Achieving cooling targets depends on ambient conditions, but users have lowered their crop temperatures to 15°C within 13 days of harvest, 10°C in less than 2 months and 5°C by the end of November.
Barn Owl Wireless automatic fan control saves at least 40% of the energy cost of cooling and drying crops. Using an algorithm that responds to readings from the nearest crop temperature sensor, the fans operate independently and only when the ambient air is suitable. Overall, this means that fan use is as efficient as it is possible to be. The Barn Owl Wireless webpage uses energy unit cost and fan running time to calculate actual costs. Users have spent as little as £370 to cool grain to below 5°C or as low as 28p per ton to reach target temperature.

Barn Owl Wireless Data Service

Barn Owl Wireless combines the technology of radio transmission within the user’s crop storage site, the GSM international SIM network for data upload onto the cloud server and a bespoke Gateway programme that ensures trouble-free operation. This and the supporting Martin Lishman Barn Owl Wireless Data Service gives the following benefits:

  • Data transmission to and from the user’s storage site, with data stored and backed up in secure web servers on the Microsoft cloud network and available for download in both graphical and tabular formats.
  • The user can access the system via the internet from PC, laptop, tablet or smartphone from any location. No software is involved or required.
  • Webpage creation to match the user’s site and facilities, automatic system upgrades, and office hours support from the Martin Lishman team if required

Barn Owl Wireless Components

Barn Owl Wireless is a modular system with no limit to the quantity of sensing points in the crop or automatic control options for cooling or drying. Martin Lishman will always help with designing and building the most appropriate system for each store. The components shown below can used to make up a Barn Owl Wireless system for any situation! Contact us today to discuss your requirements.

Basic System Components

Barn Owl Wireless Gateway

Gateway

The Gateway is the communications hub of any Barn Owl Wireless system, loaded with a bespoke programme that ensures trouble-free operation. If the GSM network is out of action, the Gateway retains all sensor readings, continues automatic fan operation and transmits the data when communications are restored. Usually only one Gateway is required where the storage buildings being monitored are in close proximity.

barn owl wireless bridge

Bridge

Bridge units are mains powered transmitters that send data between the building where the Gateway is located and other storage buildings in close proximity. One Bridge is usually required for each additional building.

barn owl wireless booster

Booster

The Booster is a mains powered transmitter used as a staging point in an installation with large numbers of sensors or to increase the range between buildings, and ensures that data reaches the Gateway. Bridge units, Ambient Sensors and automatic controllers also carry out the same function, so the need for a Booster will depend on the overall installation set-up.

Crop Temperature Monitoring Components

Crop Temperature Sensor

A battery powered radio transmitter attached to a 2 or 3m rigid crop sensor that displays the crop temperature and transmits data via the Gateway to be displayed on the user’s webpage.

A 4 way version is available to use 4 flexible cable sensors of lengths up to 40m in potato stores. The transmitter displays the potato temperature from each connected sensor and transmits data via the Gateway to be displayed on the user’s webpage

barn owl wireless silo sensor

Pendant Temperature Sensor

A steel core cable with digital sensors at 2 or 3m intervals, ideal for deep stores and silos where sensing is required through the entire depth profile of the crop. The pendants are suspended from a suitable anchoring point in the structure roof and connected to a multi-sensor transmitter. In flat floor stores they would be positioned at the midpoint between Pedestals or ventilation ducts.

For silos, pendants up to 60m long can be installed to suit the diameter and height of the silo.
