… hiring workers are increasing, which results in more cows per animal keeper. Sensors can then be a great tool for keeping track of animals which need special attention. With a reported decreasing fertility, sensors that can detect oestrus even at low levels can be especially …
… to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this …
tillämpning av en Arduino mikrokontrollerplattform och HC-SR04 sensorer
… away. In this project, the Autonomous car with microcontroller and ultrasonic sensors, we are looking at a way of making a small, regular RC car autonomous with relatively simple means and investigate how the big companies does it to learn more about the development of the …
… appliance, especially robots and self-going devices are used different sensors. One of the most used movement sensors are accelerometers. They are three different types of accelerometers one-axes, two-axes and three-axes. They can be analogue or digital. Husqvarna AB uses an …
… the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could …
… using suction cups. The environment is harsh and many traditional positioning sensors are not suitable for implementation. This thesis investigates the possibility to use a gyroscope and a pressure sensor to create an alternative and independent positioning system. Together with …
In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of …
… In almost all pneumatic cylinders, magnets are mounted on the piston. Magnetic sensors are then used for proximity sensing to detect its extreme positions. A similar way can be used for velocity sensing. Assume that two magnetic sensors are placed on a fixed distance between …
… travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition …
… concept only with a greater number of input ports, better range of applicable sensors and an advanced yet easy to use interface. The system is supposed to be placed at Rapid's test department where it will be used as a tool for finding faults and provide data which can be used …
… of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67. The methods applied have been taken from the book ”The Mechanical Design …

… of a situation picture in the land arena, with the help of the technical sensors that exist today?" and to develop a basis for continued research in the field situation in the concept Networking Enabled Command, Control and Collaboration (NEC3) at JCDEC (Joint Concept …
… of calving in beef cattle. In the study sixteen Standing- and lying down sensors were attached to the leg of sixteen beef cows. Ten of the sixteen beef cows gave birth to calves during the trial period. From these ten cows, data from six cows were used to assess the sensors …
… using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control …
… a building by calculating the impact made by its? occupants. This is done by sensors, the most common one are carbon dioxide sensors. A different solution would be to calculate the number of occupants and then calculate the carbon dioxide levels from that number. This paper …
