Arduino Weather Station with DHT11 and BMP180

In the previous tutorial I showed you how to build a weather station using only the DHT11 sensor and I said the readings from this sensor is fairly accurate. In this tutorial, I will be using the DHT11 to measure only the humidity and BMP180 to measure pressure and temperature. That’s because its readings are more accurate than the DHT11 temperature readings.

Arduino Weather Station using DHT11

Using a display to view the temperature and humidity of your environment can be possible using the DHT11 or DHT22 sensor with the easy to use Arduino microcontroller platform and that’s the goal of this project. For this project, we will be using the 16×2 LCD display module to display the temperature and humidity readings gathered from the environment using the DHT11 temperature and humidity sensor.

How to Set Up the DHT11 Humidity Sensor on an Arduino

circuitbasics.com has a new tutorial on how to interface DHT11 humidity sensor to Arduino board. Sample code is provided

Because of their low cost and small size, DHT11 humidity and temperature sensors are perfect for lots of different DIY electronics projects. Some projects where the DHT11 would be useful include remote weather stations, home environment control systems, and agricultural/garden monitoring systems.

DHT11 Temperature and Humidity Sensor with Pinguino

dht_protoboard

DHT11 is a common humidity & temperature sensor. This sensor has a single wire serial interface with special timing diagram for the single wire interface.

When the MCU sends a start signal, DHT11 sends a response signal followed by the humidity reading and then the temperature reading.

To know more details about the operation of DHT11, a project on hackster.io made by Jan Zumwalt, demonstrates how you can connect DHT11 with Olimex Pic32 Pinguino Micro.
Jan said that he tested the code with a DHT11, and should work with DHT22. DHT22 have a larger ranges for humidity and temperature readings.

Easy IoT weather station with multiple sensors

FYF88KDINI7SBPP.MEDIUM

user Ingenerare @ instructables.com published a tutorial on a IoT weather station based on NodeMcu board, DHT11/22 sensor, BMP180 sensor, Rain sensor, Light sensor.

In this tutorial, I will walk you through the steps to build an easy and cheap IOT weather station. The retrieved data is pushed via a wifi shield to Thingspeak. The data can be analysed on the Thingspeak channel or on a personal website as can be seen in the pictures above.

Quick Arduino Hygrometer with OLED display

F8FMZUCIKA08IN2.LARGE

jazzycamel @ instructables.com has published an Arduino based Hydrometer with OLED display. It uses an Arduino Leonardo Pro Micro, an Adafruit SSD1306 OLED display and DHT11 digital temperature and humidity sensor.

We have been having some condensation and mould issues in our apartment recently due to, I think, the humidity levels. Our property is relatively newly built and, as such, has very good insulation properties (double glazed windows etc.).

Remote WiFi DHT11 Temperature an Humidity Display

FXJ5AV1IJRHMFEI.MEDIUM

BoianM @ instructables.com shows us how to build a remote temperature and humidity display using DHT11 sensor and two ESP8266 modules. To program the ESP8266 modules a visual programming software is used.

The advantage of the ESP8266 over Arduino and other controllers is the builtin Wi-Fi. In this Instructable I will show you how with the help of Visuino you can use two ESP8266 modules to make a remote LCD Display for Temperature and Humidity DHT11 sensor.

Arduino OLED Thermometer And Hygrometer With DHT11

F3KNHZSIFO75QNW.MEDIUM

KonstantinDimitrov @ instructables.com has build a Arduino based OLED Thermometer and Hydrometer using DHT11 sensor.

Hello, everyone ! Today I am going to show you how to make Arduino OLED thermometer and hygrometer* with DHT11.

The OLED we will use today is .96″ inch in size, features 128×64 pixels and uses the SPI Bus.

We will use the u8glib library to communicate with our display. This library has many available parameters(download it and unzip it at /Program Files(x86)/Arduino/Libraries).

ATmega Alarm Clock & Thermometer Humidity meter

FIIBDT7IHAYI0TK.LARGE

nitram147 @ instructables.com has build a ATmega based alarm clock with temperature and humidity reading. Sensor used is DHT11.

First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there’s not something useful) brought me some cashing register display similar like that. When I first see them I knew that I will made from it alarm clock.
