Logging DHT11 data to an SD card

(adsbygoogle = window.adsbygoogle || []).push({});

This is another simple project using a Wemos MIni and a couple of shields. This time we will connect a DHT11 shield and an SD card shield and we will log some temperature data from the dht11 to an sd card. The data will be saved as a csv […]

Wemos OLED temperature project

This example will take the previous Wemos OLED shield example and make something slightly more useful with it. In this case we used a DHT11 shield and are going to display the temperature and humidity on the display.

Setup

This was a picture of my initial setup with the temperature and humidity displayed, as you can see […]
