Wemos D1 mini

The Wemos D1 Mini is a small versatile card based on the ESP8266 (ESP-12). It is found for less than €5 direct from china. Very easy to use (programming via USB cable, activation of the automatic Bootload mode …), there are many expansion cards (shields). Relay (250VAC / 10A or 30VDC / 10A), 64×48 pixel OLED display (SSD1306), LiPo battery charger (via micro-USB plug, charging in operation), micro-SD card reader , 7 to 24 VDC power supply, prototyping microplate, double socket, 2 x 15VDC driver, RGB light point based on the WS2812B controller. It is very easy to develop connected objects (IoT) with the Wemos D1 Mini using the Arduino IDE or ESP Easy and integrate them into a home automation software (Jeedom, Domoticz …) or Node-RED .

The DHT22 temperature and humidity sensor (and its small brother the DHT11) are ubiquitous in the Arduino / ESP8266 / Raspberry Pi tutorials. You are also probably familiar with Dallas DS18b20 which uses the 1-Wire protocol. Wemos offers a new expansion card, the Shield SHT30. The Sensirion SHT30 is a …
