Abstract: A sprinkler controller capable of repelling an animal is illustrated and has an image capturing unit and a processing unit. The image capturing unit is used to capture images of a space. The processing unit electrically connected to the image capturing unit is used to analyze the images to determine whether an animal invades a specific zone which is selected or defined by a user in advance, and control a sprinkler unit in the specific zone to sprinkle in response to a determined result.

Abstract: A valve operating method for a sprinkler system with a plurality of electrical valves is disclosed. The method includes the following steps: receiving a user generated query signal; generating a first set of the control signals to a driving circuit of the plurality of electrical valves of the sprinkler system in response to the query signal; generating a detection signal successive to the first set of the control signals; orderly sending the detection signal to the plurality of solenoid valves; and sensing a voltage level of a sensing terminal of the driving circuit, and obtaining a sensing result accordingly. A first sub-circuit of the driving circuit is disabled in response to the first set of the control signals. The valve control device include electronic parts to implement the above-mentioned steps is also disclosed.

Abstract: A waterproof decorative strip includes a strip body, having at least one decorative surface; a film layer, assembled on the decorative surface of the strip body; and a TPU waterproof layer, disposed on an outer side of the film layer for covering the film layer and the strip body to become a whole. The strip body is covered with the TPU waterproof layer, enabling the whole decorative strip to be water-resistant and durable. The decorative strip may be used for decorating the appearance of accessories or providing the functionality of accessories. The service life can be prolonged greatly.

Abstract: A control system including a control device, an irrigation controller and a server is disclosed. The server is linked to the control device and the irrigation controller for receiving a regional information of the irrigation controller. The regional information includes a position information of the irrigation controller, a plant information and a sprinkler information. The server generates a watering schedule according to the regional information and an evapotranspiration information corresponding to the position information. Then, the server transmits the watering schedule to both the irrigation controller and the control device, so that the irrigation controller is set up according to the watering schedule.

Abstract: A housing for an electronic sprinkler controller and the electronic sprinkler controller are disclosed. The electronic sprinkler controller has a first circuit board and a terminal block electrically connected with the first circuit board. The housing includes a back cover, a first front cover attached to the back cover to cover the first circuit board, a terminal block cover, a first seal and a second seal. The first circuit board is disposed on the back cover. The first front cover has an opening to expose the terminal block. The terminal block cover is rotatable between a closed position covering the opening and the terminal block and an open position not covering the opening and the terminal block. The first seal is disposed between the back cover and the front cover, and the second seal is disposed between the front cover and the terminal block cover.

Abstract: A power line Ethernet adaptor is suitable to be applied to an external module including a first connector. The power line Ethernet adaptor includes a housing, a cover and a circuit board. The housing has an accommodating space. The cover is movably connected to the housing to move between an on-position and an off-position. When placed at the off-position, the cover covers the accommodating space. The circuit board is disposed in the accommodating space and has a power line Ethernet module and a second connector. When at least a part of the external module is disposed in the accommodating space, the first connector and the second connector are electrically connected to each other to establish the signal connection between the external module and the power line Ethernet module, and the cover also covers the external module when placed at the off-position.

Abstract: A controlling system includes a server, a first controlling device and at least one second controlling device. The first controlling device is connected with the server. The first controlling device receives an information coming from the server and sets a first value of the first controlling device according to the information. The second controlling device is connected with the server. The information represents a second value of the second controlling device. The second controlling device is disposed within a predefined geographical area.

Abstract: An operational amplifier is dynamically accelerated depending on its internal state. Acceleration is disabled when the internal state indicates a risk of instability. When the internal state of the operational amplifier indicates no risk of instability, the acceleration is turned on to speed up the circuit operation.
