Description:
|
This application note describes a Microchip system solution for a low end/power wireless home security system. This design implements an HCS200 encoder for the intruder sensor signal encryption, one PIC12C508A PICmicro ® for sensor monitoring and RF signal initiation, HCS515 decoders for decrypting the received intruder sensor signal and a PIC16C77 PICmicro for base station panel monitoring and control. Other support logic is included, such as a battery back-up circuit, simple single stage lead acid battery charger and external siren control, but the focus of the application is the implementation of Microchip KEELOQ ® and PICmicro products for a complete solution.
