My original proposal for a door lock monitor using the EnOcean STM 320U Magnetic Contact Transmitter Module is shown in Figure 1. In this proposal, I planed to remove the reed switch from the module and re-attach it with wires so that the reed switch could be placed in a hole drilled into the frame and sit just shy of the bolt went the lock was engaged. The bolt would have a thin magnet glued to it to provide the magnetic field to engage the reed switch.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
