The PT2272-M4 (Rx) receiver module is designed to be used in conjunction with the PT2262 (Tx) transmitter module (Item HCMODU0040). When used together they are a set of wireless modules operating at 315MHz and utilise the the Princeton Technology Corp PT2262 & PT2272 remote control encoder and decoder IC's. They provide an easy way of remotely controlling up to 4 channels without the need of a microcontroller. This makes them ideal for applications such as security systems, garage door controllers, home automation, and remote control.
