Automation by the use of computer screen


Automation by the use of computer screen.

Computer screen can serve as trigger for photosensors which inflict voltage on relays which perform automation. This principle was implemented by L-Data in a new product, called LD-4. LD-4 is a light triggered relay board which is connected with the light sensors to the front of a computer screen. On the screen there are several rectangles which change their color from black to white according to the needs. The color change causes the photosensors to inflict different voltage on the relays which in response switch on or off. The computer program is connected to the internet and user can switch on/off devices from the web. Different automation logic can be added (time schedule, time period or sensor dependant) and historical view of the automation can be viewed. Automate your devices from everywhere. Set automatic timer for devices. Automate with relation to sensors readings.
