Environment Sensorbox for Wemos D1 Mini and a lot of sensors
thingiverse
I designed this body for my "Environment-Supersensor" setup. This is the first design, with updates and changes to follow. The motivation is to measure most of the environment data in one device and transmit these data to my home automation system. It's based on a ESP8266 "Wemos D Mini" and the newest ESPeasy version, which I compiled by myself in Arduino on a Mac. On the ESPEasy project pages, pre-compiled versions are available too. You can find my personal compiled version in the file section. If you have problems with uploading the firmware to the ESP, check if you have the right USB driver installed on your system. You should check this site for the needed USB-TTL driver: https://www.letscontrolit.com/wiki/index.php?title=ESP_Hardware The following items are connected to the WEMOS D1 Mini: * Display: OLED SSD 1306 128x64 (1.3 inch version) - two versions of the body are included, with the second version for the 0.96 inch version * Temperature, Humidity, Air Pressure Sensor: BME280 (4 pin/small version) * Light Sensor: BH 1750 * CO2 Sensor: MH-Z19 The two small notches are for the BH1750 and BME280. The Wemos D1 Mini and the CO2 have no fixation right now. The image with the cabling is for a better understanding only.
