Potato Temperature Monitoring

Three reasons to measure Potato Temperatures

  • Temperature monitoring gives early warning of quality problems and the opportunity to take action before the situation gets worse
  • Monitoring shows whether temperature targets have been reached – which can save energy by avoiding unnecessary ventilation use
  • Monitoring allows accurate and confident control and management of the stored crop

Simple Temperature Monitoring

MiniTemp Monitor with Single Flexible or Rigid Sensor

For temperature measurement in bulk or box stored potatoes. A simple and inexpensive way to measure crop temperature and conform to quality assurance schemes.

Key Features

Easy to use – place sensor in the potatoes when filling and connect to the MiniTemp monitor
Latching connector – prevents accidental disconnection
Flexible sensors – can be any length, up to c. 50m

Multi-Sensor Temperature Monitoring

For a simple potato box or bulk store multi-sensor monitoring system. Sensors can be any length, up to c.50m. Monitor and sensor selector can be conveniently located at ground level.

Key Features

Fast monitoring– and ensures readings are always from the same part of the box or store

Saves time – allowing faster decisions about store management

Simple, convenient and inexpensive – allows flexibility in store monitoring design

The Multi-Sensor Selector provides multiple temperature records quickly

How does the Multi-Sensor Selector work?

The Multi-Sensor Selector is a junction box capable of having up to 12 crop temperature sensors plugged into it. It is supplied with a lead to connect it to a MiniTemp monitor. A rotary selector connects each crop sensor in turn to the MiniTemp which displays the sensor temperature reading.

Barn Owl Wireless is a modular multi-sensor monitoring and automatic ventilation control system. The flexibility of the system makes it ideally suited to potato store monitoring in all sizes and types of store.

Barn Owl Wireless sends live temperature updates to the store manager.
The Barn Owl Wireless webpage shows historical temperature and fan use data in graph or table format

Key Features

  • Web-based system– no software to install or on-site PC required.
  • Automatic control – with independent control of each ventilation fan, using a range of programmes, providing significant energy cost savings
  • Remote monitoring – avoids driving to stores to record temperatures or operate ventilation systems
  • Verifiable data records – showing store temperature profile, ventilator usage, cooling costs
  • Modular system– with no limit to the quantity of sensors or automatic controllers

How Barn Owl Wireless works

Wireless radio transmitters are attached to flexible crop sensors in boxed or bulk stored potatoes. Temperature data is transmitted by SIM card to the internet and can be accessed from any location. Automatic fan controllers give independent control of each ventilating fan using a range of programmes, providing significant energy cost savings.

The Barn Owl Wireless webpage reproduces the box store to show temperatures in each layer and identify areas requiring cooling or ventilation

Barn Owl Wireless step by step

1. Temperature data in the potato store is sent to the gateway

2. Data is sent to the cloud via the GSM network

3. Data on the webpage is accessed via the Internet

4. Fan controls are selected on the webpage

5. Fan controls are sent to the gateway

6. Fan controls are sent to fan controllers to turn on/off extraction fans
