The Cebek CD-25 module is a digital clock and thermometer module with a 4 digit multiplexed output to drive 7-segment LED display modules (see table below for suitable display boards). The circuit uses a Quartz oscillator to provide a high degree of accuracy.
The module can output just the Clock signal, just the Thermometer signal or both (with the output cycling between the Clock and Thermometer signals). In cycling mode, the time period each output is displayed for can be adjusted between 1 and 8 seconds.
The clock function outputs Hours and Minutes in a 24 Hour format.
The thermometer can be set to output degrees Celsius or Fahrenheit. The measurement range -23 to 105°C. The small temperature probe board supplied carries an LM335 precision temperature sensor and can be connected with up to 100cm of screened cable (not included).
A backup battery input is provided to prevent memory loss should the main supply be disconnected.
It can be used to drive Cebek displays CD-23, CD-24, CD-53 or CD-54.
