Outlet Mounted Multi-Sensor
thingiverse
<h1>Summary</h1> This is an ESP8266-based multi-sensor that is mounted by plugging it into a standard US-type outlet. It supports the following: - AM312 motion sensor - BH1750 light sensor - SHT31-D temperature and humidity sensor <h1>Features</h1> - USB charger can be rotated to accommodate different outlet orientations - Small PIR motion sensor housing can be angled toward area of interest - Ventilation added to improve temperature and humidity readings. I didn't have good luck with the BME280. I still needed to calibrate the SHT31 so it isn't perfect. - Small wiring access port for future expansion - Snap-fit enclosure design - Minimal size won't block the other outlet <h1>Design Details</h1> The smallest readily-available USB wall charger I found was this one: https://www.amazon.com/gp/product/B07RXZ72RJ/ The case size could be reduced by sourcing a smaller charger. 1A is sufficient for the D1 Mini. To keep the cover as short as possible, I created my own USB cable using the following solder jacks: https://www.amazon.com/gp/product/B07TBL5Z9T https://www.amazon.com/gp/product/B07G5ZY7MH Used 30AWG flexible silicone wire as the space gets used up quickly: https://www.amazon.com/gp/product/B01KQ2JNLI <h1>Parts List</h1> - <p><a href="https://www.amazon.com/gp/product/B08C7FYM5T"</a>ESP8266 D1 Mini</p> - <p><a href="https://www.amazon.com/gp/product/B08PVB7VHQ"</a>AM312 motion sensor</p> - <p><a href="https://www.amazon.com/gp/product/B085WBFCMF"</a>SHT31-D Temperature and Humidity Sensor</p> - <p><a href="https://www.amazon.com/gp/product/B00M0F29OS"</a>BH1750 Light Intensity Illumination Module</p> - <p><a href="https://www.amazon.com/gp/product/B07RXZ72RJ/"</a>USB Wall Charger</p> - <p><a href="https://www.amazon.com/gp/product/B07TBL5Z9T"</a>USB 2.0 Male Port Connector Solder Jacks</p> - <p><a href="https://www.amazon.com/gp/product/B07G5ZY7MH"</a>Micro USB Male Type B 5-Pin Jack Port Solder Connector</p> - <p><a href="https://www.amazon.com/gp/product/B01KQ2JNLI"</a>30 AWG Flexible Silicone Wire</p>
