This week, James Wolf shared a PIR sensor project he’s working on to monitor his dog while he’s not at home. Check it out here!
I am working on something that will let me know if the dog is getting on our bed while we are at work. This way I can remotely monitor the device using cURL from the office.
The PIR sensor goes off when it sees a change in the infrared signature in front of it (i.e. someone walks in front of it). Eventually I am going to add a noise making device to it that should go off when she jumps on the bed and will eventually train her to stay off.
Right now it is using Server-Sent Events (HTML5) so that anything that subscribes to the event gets an indication of the PIR going off, but I can easily update the firmware from anywhere and change how and what I am monitoring in real time without ever unplugging it. I love the +Spark!
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.
