Wall controller box (2 Wemos D1 mini & clap sensor)

myminifactory

This is a part of my affordable smart home series. This box contains a lot of smart home tech in one place. I needed a way to house two Wemos D1 mini boards to control a WS2812B LED strip and a clap sensor as well as a temperature sensor. Everything is held together with a single screw. The remaining parts are glued or locked securely. Left Wemos D1 mini The left Wemos D1 mini is flashed with McLighting, an awesome project that lets you control your LED strip via a web interface with many preprogrammed animations, and controls the LED strip. Right Wemos D1 mini The right Wemos D1 mini runs self-written Arduino code. The code checks the signal from the clap sensor (in the middle) and measures the room temperature every two minutes. The results are sent to my smart home server via MQTT. So if someone claps, the light turns on or off, and the temperature information helps my thermostat project. Clap Sensor The Clap Sensor works very reliably once calibrated. However, the amplification wasn't strong enough, so I added those "ears" to get a range of multiple meters. Now the sensor can easily cover a big room. It's even sensitive enough to recognize the small pressure wave of a door getting closed a couple rooms away. So it's also a door sensor. Temperature sensor The temperature sensor is just a resistive thermocouple I salvaged from an old thermometer. Power The power for the project is provided via the black cable at the bottom. I chose an old PC power supply to supply 5V for everything. Hardware: Wemos D1 mini Clap sensor thermocouple WS2812B LED strip powerful 5V power supply I don't know how I'm able or if I should upload the Arduino code. I wrote it myself, and to be honest, it's pretty terrible, but it works. I'm a beginner in programming. If it's requested, I will upload the code, but be sure to see a mess. I tested the design for several months and never had a failure. So I am very confident to say that it is very reliable.
