agriculture sensor Applications

  • Wine Analysis

    In France, ammonium levels in wine are limited to 20 ppm, we have developed a protocol for using our solid state sensor for measuring ammonium in all stages of wine production.

    Soil moisture monitoring for Agriculture Science and Research

    Accuracy and ease of use make SM300 Soil Moisture Sensors well suited to irrigation applications. Readings can be used to optimise irrigation scheduling, or the SM300 can be installed as part of an automatic irrigation system. The sensor`s compact size allows it to be installed in plant pots or grow bags.

  • Silo Grain Remote Monitoring

    Wireless sensors for monitoring grain quantity in silos. Grain level is measured and volume or weight are calculated. Information is transmitted over a cellular network to a central server for viewing over the Internet. Additional information includes temperature, power supply status and cellular signal strength. Authorized users can browse and view the state of each silo.

    Gas Sensing for Horticulture

    Controlled Environment Horticulture is a vast topic, and has been utilised in varying forms for centuries. Excavations of the city of Pompeii showed remains of early greenhouses dating back to AD79; and the modern greenhouses are thought to originate in the thirteenth century in Italy. Most people recognise the use of greenhouses for growing flowers and vegetables, whether in their own garden, at garden centres or on a commercial basis. Indeed most people will be conversant with irrigation systems that are used to supply water to such greenhouses and the use of heaters to control the temperature and thereby extend the growing season. However, modern systems have been developed for Controlled Environment Horticulture that are designed to further optimise the growing conditions; with sophisticated computer controlled sensors, combined with advanced software models, that can control not only the temperature, light level and water, but also the level of nutrients, humidity, pH and CO2

  • Monitoring of Harmful Algae Blooms

    At frst it seems impossible: how can a sensor on board of a satellite circling the earth at an altitude of some 700 kilometers not only identify the total biomass of algae in the water, but also identify species of algae. This is related to what remote sensing specialists call the refectance spectrum of the water. The spectrum is a specifc fngerprint that is created by measuring the refection of water using extremely sensitive sensors, either onboard of a satellite or inside our equipment on the ground. We use a variety of algorithms to translate refectance spectra into concentrations of specifc compounds and phytoplankton species

  • Measuring Ion Concentrations in Hydroponics Samples

    Required Apparatus:

    • Aptisens Digital or Mobile Multiple Ion Kit

    Required chemicals:

    • Aptisens multiple ion conditioning solution
    • Aptisens multiple ion HORTICULTURE calibration solutions
    • Deionised water

    Sample Preparation:
    Typically, it is not a requirement to filter a hydroponics sample.

    Calibration:
    Before use the multiple ion probe must be conditioned in Aptisens multiple ion conditioning solution. Ensure the correct calibration solutions for a three-point calibration are set up on the Mobile meter or MeterLink. Follow the instructions for calibration and proceed to take a sample reading when the calibration data is ‘very good’ or ‘good’ for all ions.

    Sample Reading:
    Place the probe in the aqueous extract and ‘Take a Sample’ reading. The concentrations for each ion will be displayed in ppm or mmol / L.

    Probe Care:
    After taking your reading be sure to remove the sensors from the solution as quickly as possible, rinse with deionised water and replace the cap of the probe.

  • Industrial solutions for agriculture monitoring

    Using wireless sensor networks within the agricultural industry is increasingly common, as it provides many benefits to the farmer, impacting both the quality of the crops and the overall operating costs. WSN address the traditional monitoring problems related to oudoor areas, by removing the need of cables and of power sources in locations where no infrastructure is available. WSN are also specially suitable for temporary or problem-solving deployments, and to gather more numerous and more consistent data.

  • Measuring Ion Concentrations in Plant Tissue

    Measuring Ion Concentrations in Plant Tissue

    Required Apparatus:

    • Aptisens Digital or Mobile Multiple Ion Kit
    • Weighing scales
    • Liquid measurement device e.g. graduated cylinder
    • Bowl for stirring
    • Spoon for stirring
    • Funnel
    • Filter paper / muslin
    • Conical flask / vessel

    Required chemicals:

    • Aptisens multiple ion conditioning solution
    • Aptisens Plant Tissue multiple ion calibration solutions
    • Deionised water

    Sample Preparation:
    This preparation can be applied to any plant tissue. Take a sample of lettuce and remove any soil but do not wash the plant tissue as doing so may reduce the number of ions in sample. Weigh this sample and record (say 100 g). Macerate the plant tissue in a blender and add a known amount of hot deionised water to the sample to extract the nutrients. For example, dilute the sample two-fold (200 mL), three-fold (300 mL) or five-fold (500 mL). Ensure all the plant tissue is covered with water and leave to sit for approximately 30 min with some stirring. The sample then needs to be filtered.

    Set up a funnel with folded filter paper in a conical flask or any vessel that can hold a funnel. Pour the plant tissue and water into the funnel and allow the mixture to filter. Collect the filtrate.

    Calibration:
    Before use the multiple ion probe must be conditioned in Aptisens multiple ion conditioning solution. Ensure the correct calibration solutions for a three-point calibration are set up on the Mobile meter or MeterLink. Follow the instructions for calibration and proceed to take a sample reading when the calibration data is ‘very good’ or ‘good’ for all ions.

    Sample Reading:
    Place the probe in the plant tissue filtrate and ‘Take a Sample’ reading. The concentrations for each ion will be displayed in ppm or mmol / L.

    Remember to multiply these concentrations by the dilution factor.

    Probe Care:
    After taking your reading be sure to remove the sensors from the solution as quickly as possible, rinse with deionised water and replace the cap of the probe
