Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

Be pound poor and become Penny rich

Energy management is and should be perceived as a long-term investment by organisations. Having said this, the need for all organisations to implement energy management strategies now cannot be overstated as these strategies will save their costs of running the business in future.

Many organisations may shy off from implementing energy efficiency measures in place opting to save the associated costs or to use the cash for other projects that may be perceived as high priority in the short run. This is most likely to occur when cost cutting is a priority. Long-term planning is however critical for energy efficiency programs. Taking steps to improve building management and energy efficiency will and does pay dividends in the near-term and may be a competitive tool in the long-term.

Be energy smart
All energy management projects begin with being energy smart which calls for the understanding of energy usage. Use of Smart Meters that give real time readings of energy usage, can dramatically help businesses understand the benefit which energy management brings to the organisation.

Smart meters also cut the amount of time businesses spend on administration by allowing them to pay accurate bills, based on accurate readings. Some suppliers also support businesses to identify areas of energy wastage/inefficiency and help setting targets for energy reduction that guide behavioural change with regard to energy in the organisation.

Use of technologies that record the energy usage at the water or electricity meters putting data into a system where the users can graph it has made it easy to compare energy consumption in various departments, sites or buildings. Appropriate measures can then be implemented to improve the efficiency.

Partnerships between businesses and energy suppliers
Since the long-term benefits of reduced energy consumption is beneficial to both suppliers and consumers; the responsibility of managing energy consumption is being taken by both. Businesses should work with the suppliers on cost reduction strategies through identifying areas where energy is being wasted and advising businesses on how to save energy. Of key importance when choosing an energy supplier therefore is their depth of understanding of a business’ energy management needs.

Capitalise on government incentives
Businesses should always explore varied financing mechanisms for their energy efficiency programs e.g. government schemes generating electricity and selling it to the grid.

Authentication and Access Control

Threats to your data can come from external or internal sources.

  1. There are individuals who don’t have the authorisation but are driven by malicious intentions to gain access to certain information. This may refer to individuals who already belong to your organisation (but don’t have the necessary access rights) as well as those who don’t.
  2. There are individuals who have both the authorisation and, unfortunately, the malicious intentions over certain information.
  3. Finally, there are individuals who have the authorisation, no malicious intentions, but have accidentally exposed the information in question to those without the proper authority.

While curbing threats 2 and 3 would require other methods, threat #1 can be countered if the right authentication and access control systems are in place.

Here’s what we can do for you:

  • Work with your key personnel to determine who gets access to what.
  • Help you decide whether a single factor or a two-factor authentication (2FA) is appropriate for your organisation and recommend which factors are most suitable. Login methods may include but are not limited to the following:
    • biometric devices
    • Kerberos tickets
    • mobile phones
    • passwords
    • PKI certificates
    • proximity cards
    • smart cards
    • tokens
  • Install the necessary infrastructure needed for the factors chosen. For instance, if you opt to use biometrics, then biometric scanners will be installed. We’ll make sure that the authentication terminals are situated in places where achieving optimal traffic and work flow has been taken into consideration.

Other defences we’re capable of putting up include:

ESOS Guide for UK Manufacturers Available

The Engineering Employers’ Federation (EEF) is the UK’s largest sectoral structure. Its goal is to promote the interests of manufacturing, engineering and technology-based businesses in order to enhance their competitiveness.

EEF has positioned itself in London and Brussels in order to be in a position to lobby at EU and Westminster level. Part of its role is helping its members adapt to change and capitalise on it. When it discovered that a third of UK manufacturers must comply with ESOS (and 49% had not even heard of it) EEF decided it was time to publish a handbook for its members.

According to EEF’s head of climate and environment policy Gareth Stace, For the many manufacturers that have already taken significant steps to improve energy efficiency, ESOS can be viewed as a ?stock taking exercise?, ensuring that momentum is maintained and new measures are highlighted and taken when possible?.

He goes on to add that others that have not begun the process should view it as an ‘impetus’ to go head down and find the most cost-effective ways to slash energy costs. Ecovaro adds that they would also have the opportunity to reduce carbon emissions almost as a by-product.

Firms with more than 250 employees, over 250 million revenue or both must comply with ESOS across all UK sectors. In simplest terms, they must have conducted an energy audit by 5th December 2015, and logged their energy saving plan with the Environmental Agency that is Britain?s sustainability watchdog.

The Department of Energy & Climate Change (DEEC) that oversees it believes that large UK businesses are wasting ?2.8 billion a year on electricity they do not need. Clearly it makes sense to focus on larger targets; however EcoVaro believes those halfway to the threshold should voluntarily comply if cutting their energy bills by 25% sounds appealing.

We are able to assist with interpreting their energy audits. These are often a matter of installing sub-meters at distribution points, and reading these for a few representative months to establish a trend. Meters are inexpensive compared to electricity costs, and maintenance teams can install them during maintenance shutdowns.

Ecovaro helps these firms process the data into manageable summaries using cloud-based technology. This is on a pay-when-used basis, and hence considerably cheaper than acquiring the software, or appointing a consultant.
