Programmable Room Sensor (PRS)

The programmable room sensor controls room temperature for all the heating systems. A display maybe mounted in the control panel to provide a user interface for control of the central heating. Some room sensors may include remote access via an Infra-Red (IR) control unit.

Application example:

78K0/K0S Family Device Features

• LCD controller/driver on chip from 5 x 4 up to 48 x 48 Segments - For displaying temperature, time or control information.
• 10 Bit A/D converter - For room temperature measurement.
• 32 kHz real time clock timer unit - For LCD clock and standby mode release
• UART, SBI or I2C interface - For remote communications.
• Key return ports - For keyboard interface
• Interrupt and timer processing unit - For IR decoding function
• Wide supply voltage operation range and low power consumption - For battery operation.
