The SENTRY M1 Radio Frequency (RF) module is a compact superheterodyne receiver module designed to detect Amplitude Shift Keying (ASK) remote control transmitters operating at 433.925MHz. The Sentry M1 is a versatile communication board that is designed to interface directly to the I/O pin of any microcontroller or decoder IC (MC145028, HT12, ESP… etc). The module has an integrated data slicer, which provides clean demodulation (to TTL) levels of ASK signals typically generated by wireless remote controls. A level shifter may be required for use with microcontrollers that have 3.3V or lower I/O requirements.
