ESP8266 MultiSensor housing

thingiverse

This is my inaugural drawing created in Fusion360. It's a multi-sensor system built around the ESP8266 or WEMOS. With a WEMOS, I utilized a breakout board to distribute the supply voltages: 3.3V, 5V, and GND. A DHT22 temperature sensor is employed to measure temperature and humidity. I made an effort to encase the sensor as much as possible from the self-heating of the WEMOS. An AM312 PIR in front detects motion. The firmware generates an interrupt and communicates the motion status to the MQTT server. A Lilypad RGB LED is used to produce a minimal light triggered via the PIR through the MQTT server. A TEMT6000 sensor on top indicates light changes (still under evaluation). I used a SMD LED lid as cover. The housing or multi-sensor can be equipped with an additional 3.3V relay to control an external light. I added one more cover to separate high voltage from low voltage control signals. The complete design is made to connect with jumper cables, requiring minimal necessary soldering.
