This is a DIY project for an RS232/RS485 Wireless Receiver for the Skylink RF protocol. It can be constructed on our general purpose GP-DIY-PCB printed circuit board.

Skylink is a value priced line of wireless security sensors that use 318MHz in the US and 433.92MHz in Europe. Skylink devices are available from Smarthome as well as from other dealers.

The HA318T Motion Sensor sends a 14 bit code like the one below.
