masterfoxxhu/wifi_homesensorQuick and dirty ESP8266 based thermo and humidity meter for ESPhome
Wifi homesensor is an open-source printed circuit board by masterfoxxhu, from the masterfoxxhu/wifi_homesensor repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 53.3 × 64.4 mm with 33 parts on 26 nets, routed with 165 tracks and 168 vias.
It is built around the WEMOS D1 MINI, MCP16301-E/CH and SHT31-DIS-F, with the LL4148, SM6T15A and SS26FL among its other parts. Its parts include 8 capacitors, 8 resistors, 5 diodes, 3 ICs and 2 connectors. It belongs with the radio and wireless boards and the ESP8266 boards of this library.
Quick and dirty ESP8266 based thermo and humidity meter for ESPhome
Based around a Wemos D1 mini module, using SHT31 sensor, and a MCP16301 DCDC converter.
Enclosure PA62W
A render of the board.
The sensor is located on the bottom of the board to minimise heat pickup from the rest of the board. There is a vent near the sensor on the enclosure.

It measures 53.3 × 64.4 mm and has 2 copper layers, 1.6 mm thick.
33 parts, built around the WEMOS D1 MINI, MCP16301-E/CH, SHT31-DIS-F and LL4148. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the masterfoxxhu/wifi_homesensor repository on GitHub, at the commit this page was made from: the board is Wifi_homesensor.kicad_pcb and its schematic Wifi_homesensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
