Temperature, Humidity, Moisture Sensor with OLED
prusaprinters
<p>Temp, humidity, soil moisture sensor with an OLED display in a tiny package. It also logs the data to thingspeak.com for some nice graphs.</p> <p>Required parts:</p> <p>DHT11 Temperature/humidity sensor</p> <p>Capacitive Soil moisture sensor</p> <p>Wemos D1 mini</p> <p>0.96inch OLED display (I mistakenly bought a SPI version so the code is written for that)</p> <p>I've attached the code, you'll need to create an account on thingspeak.com for the cloud data but it should work as a stand alone display.</p> <p>In Thingspeak set up a channel, add Temp to field1, Humidity to field2 and Moisture to field3. Save the channel and select the API Keys tab. Copy your write key and add it to the code.</p> <p>Connect the following wires:</p> <p>DHT11 data pin --> D2</p> <p>Moisture sensor data pin -->A0</p> <p>OLED_MOSI --> D7</p> <p>OLED_CLK --> D5</p> <p>OLED_DC --> D4</p> <p>OLED_CS --> D8</p> <p>OLED_RESET -->D0</p> <p>I'm no expert in coding so if you look at the code and see something that could be improved please let me know. For example I couldn't work out how to send the progress bar updates without adding it 10 times. I'm sure there is an easier way of doing it.</p> Category: Electronics
