Mini Motion and Light Sensor - Wemos D1 Mini

cults3d

I use a lot of ESPHome based movement and light sensors within my Home Assistant setup and wanted to come up with the smallest practical design that would house a D1 Mini Clone, AM312 PIR and an LDR for rudimentary light level sensing. This is the design I came up with. Has a clip frame for the D1 Mini (fits the majority of boards with the angled corners). There are 2 versions of this file. Version 1 is designed to be used with the stripboard frame. Version 2 without. The AM312 is a push fit from the front and the LDR legs also push in through the font (I used a dab of superglue gel to fix the LDR). There is also a frame to mount a small piece of stripboard so you don't have to put the resistor for the LDR in line. There's also 2 versions of the case. One just for the PIR and LDR. The other has a cutout for a DHT22 temp/humidity sensor. Please note, this sensor would be very close to the D1 Mini which will affect temperature readings. Top and bottom panels are designed to be attached using M2 cap head screws. This design is offered for free but if you do find it useful, please consider buying me a beer by using the Donate link below - it did take many hours to perfect.
