Compact Presence Sensor Case

A case for an ESP32-C3 supermini and an HLK-2450 human presence sensor. I use it for HomeAssistant with Esphome. To fit the sensor into the case, you need to cut off the connectors, and directly solder to the exposed pads.It uses the integrated USB-C port on the ESP for power. After testing, I glued the case shut, to prevent it from opening.The back is marked so you can remember which way is up. I used Velcro to attach my unit to the wall (see picture).My full Esphome configuration is provided in the documentation section (with an extension of .txt). You may want to use this image as a reference when positioning the sensor inside the case:(As viewed from the front of the sensor)(Image source) AliExpress links for the exact products I used:Presence SensorESP32-C3 supermini (there are a lot of sellers that offer the same footprint)
