Specifications

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

Potato Temperature Spikes

For quick and accurate temperature measurement in individual tubers

Key Features

Two accuracy ranges available: +/- 0.3°C or +/- 1°C
Stainless steel probe – with thermistor sensor
Data hold function – to retain displayed value
High contrast LCD display – with function indicators
Waterproof polycarbonate case – with membrane keypad

Single-Sensor Temperature Packages

MiniTemp Monitor
Portable Measurement Package

For temperature measurement in bulk or box stored potatoes. A simple and inexpensive way to measure crop temperature and conform to quality assurance schemes. Comes with either a 600mm, 1.5m or 2m fast response stainless steel sensor with T-bar handle.

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

MiniTemp Blue
Static Measurement Package

MiniTemp Blue Bluetooth crop temperature monitor and data logger with iOS/Android App and rigid, PVC temperature sensor in either 2m or 3m lengths. Ideal for For temperature measurement in bulk or box stored potatoes.

Instant temperature readings with Android or iOS app
Avoids claiming heaps to take readings
Logs temperature data for up to 6 months
Download stored data for long-term record keeping

Multi-Sensor Temperature Packages

Multi-Sensor Selector
Potato Store Monitoring Package

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. See the specifications section below for package options.

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

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 or a Martin Lishman Temperature Differential Controller . A rotary selector connects each crop sensor in turn to the MiniTemp which displays the sensor temperature reading.

Multi-sensor monitoring packages are available including the Multi-Sensor Selector and up to 12 flexible temperature sensors of varying lengths.

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.

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.

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
