Dht11 Temperature And Humidity Sensor Arduino Code With Oled

It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin no analog input pins needed.

Dht11 temperature and humidity sensor arduino code with oled.

This will work as a brain of this project which will contain the code and send data to oled display. 5 volts power supply. The dht22 am2302 sensor is able to measure temperatures from 40 to 125 c with an accuracy of 0 5 c and relative humidity levels from 0 to 100 with an accuracy of 2 5 at extremes to 10 and 90. It s perfect for remote weather stations home environmental control systems and farm or garden monitoring systems.

It measures both moisture and air temperature. If you re not familiar with the dht11 sensor read the following article. Wemos d1 mini is another esp8266 module. In this section we ll build a project that displays temperature and humidity readings on the oled display.

The dht22 sensor also known as the am2302 reference and his little brother the dht11 are temperature and humidity sensors. The idea of using the oled display with the esp32 or esp8266 is to ilustrate how you can create a physical user interface for your boards. Oled display 0 96 inch x 1. In these tutorials we will measure temperature and humidity by using dht11 with arduino.

The dht11 humidity and temperature sensor makes it really easy to add humidity and temperature data to your diy electronics projects. Jumper wires for bread board connection. In this tutorial i ll first go into a little background about humidity then i ll explain how the dht11 measures humidity. This video show how to build a humidity meter using a dht11 humidity sensor i2c oled display and arduino uno.

We ll get temperature and humidity using the dht11 temperature and humidity sensor. The dht11 is a basic ultra low cost digital temperature and humidity sensor. Learn how to display temperature and humidity readings from a dht11 dht22 sensor in an ssd1306 oled display using an esp32 or an esp8266 with arduino ide. Dht11 temperature and humidity sensor.

A 128x64 i2c oled ssd1306 display is used to d. Display temperature and humidity in the oled display with arduino. Dht11 sensor x 1. Together with a dht22 temperature sensor the tiny oled screen will display real time humidity and temperature data using an adafruit library and an arduino uno board.

Its fairly simple to use but requires careful timing to grab data. Here we also display those readings on an lcd display. The dht11 temperature and humidity sensor senses measures and regularly reports the relative humidity in the air.
