LED display TLZ4T is designated to be use in swimming-pool. The display shows current time (hours, minutes) and four temperatures freely configurable e.g. air temperature, internal room temperature, temperature of water or constant temperatures set by remote control. To display values was applied super light 7 segments displays 4.0'' (100mm) with common anode. Clock was built on specialized chip with I2C interface and battery backup. Instead of battery was used high volume capacitor. Digital thermometer with interface 1-wire and resolution 0.1° C measure appropriate temperature. The whole display is controlled by microcontroller, which communicated via RS485 interface with each small board which managed 7-segment displays. Every digit display has got independent impulse supply circuit, what allowed to automatic adjustment of light intensity depend on data from main controller, which measure external light and adjust level of LED lighting. Plexiglas filter excellent guarantee perfect contrast. Setting time and temperature is carried out by four buttons remote control. There are available other color LED dispalys such as gree, yellow, white, orange or higher displays 5.0'' (125mm).
