RF Door sensor

Scope of work ● Electronic circuit schematic ● Component Package Selection. ● Component Placement. ● PCB layout. ● Fabrication file generation Overview of the product Detect intrusion and trigger a loud alarm Functional Requirements The functionality of this product is broken down into modules- Module1: Door Sensor ● Magnetic door sensor with Reed Switch to detect opening and closing of a door ● Houses a RF transmitter to broadcast a signal (may be 433MHz) ● A tiny programmable MCU with low deep power down current and quick wake up times using interrupts that is able to store a code and transmit along with the signal (Firmware is not part of this project) ● Two push buttons for custom functionality ● Runs on a 3V LI-ion button cell Module2: RF Receiver ● Continuously listens for transmitted signals from the transmitter. ● A tiny programmable MCU to trigger some functionality when a matching code is detected. ● Runs on AC power. So, a stable DC step down converter to 5v/3.3v is needed. It should also have enough power to drive a loud alarm and warning LEDs up to 20W. ● A push button and two indicator LEDs (tiny LEDs different from warning LEDs above) on the board.
