Many new and emerging technologies will revolutionise farming in Ireland. These include the use of advanced sensors for data collection, further development of precision agriculture, expanded use of robotics and automation and greater use of biotechnology and bioengineering in farming.
A sensor is an electronic device that detects or measures a change in the physical environment (such as temperature or light intensity), converts this measurement into a signal and, in general, sends that information to a computer or mobile app. Your mobile phone, for example, may have motion sensors, pressure sensors (on the screen), light sensors, GPS (Global Positioning System) and many more. Below are some examples of sensor technologies used today on Irish farms.
GPS & GIS Sensors
GPS, or Global Positioning System, is a technology widely used to help identify one’s exact position and speed. GPS satellites orbiting the Earth continuously transmit their own location and the exact time. Using the signals from three or four satellites a GPS receiver (as used in some smart phones) calculates its own position. GIS (Geographic Information Systems) is a similar technology which maps the surface of the Earth and can be used to monitor crop growth.
Using these technologies in precision agriculture farmers can vary the sowing rate, fertiliser application, pesticide use etc. to suit different fields or even parts of a field. GPS may be used in automated farming, in which driverless vehicles are used to harvest crops. GPS also facilitates more accurate soil sampling and better farm planning. It allows farmers work when there is poor visibility — at night or during fog.

a measure of the acidity or basicity of an aqueous solution; pH values are generally in the range 0 to 14, where 0 is a strong acid, 7 is neutral and 14 is a strong base. Negative values are possible; commercial HCl has a pH of about -1.1. Saturated NaOH has a pH of about 15.

chewing the cud'; some animals, such as cows and sheep, regurgitate and chew vegetation they have previously eaten; this help the breakdown of the fibrous tissue it contains
Science and Technology in Action (STA) is designed to support the teaching and learning of science and related subjects.
Each annual edition of STA contains a set of lessons that are industry led to be used by all teachers in second level schools. These lessons are available on this website and can be downloaded in a pdf format along with their supporting materials.
A hard copy is usually sent out for free to all second level schools each school year.
Science and Technology in Action (STA) is proudly supported and partnered by some of Ireland’s leading organisations and is produced in close cooperation with the support services of the Department of Education and Skills and the Irish Science Teachers Association (ISTA).
