DHT11 ESP Library: Download index.h CodeĬopy this code and paste it on a text document. The program for Live Weather Station Monitoring Using NodeMCU ESP8266 is divided into two parts, i.e 1. Assemble the circuit as shown in the figure below. In short, the wetter the board the more current that will be conducted.īelow is the circuit diagram for making Live weather Sation Monitoring Using NodeMCU. The sensor board acts as a variable resistor that will change from 100k ohms when wet to 2M ohms when dry. The rain sensor detects water that completes the circuits on its sensor boards’ printed leads. Rain sensors are used in the detection of water beyond what a humidity sensor can detect.
The ultra-low power consumption down to 3 μA makes the BMP180 the leader in power saving for your devices. It follows the BMP085 and brings many improvements, like the smaller size and the expansion of digital interfaces. The BMP180 is the new digital barometric pressure sensor of Bosch Sensortec, with a very high performance, which enables applications in advanced devices such as smartphones, tablet PCs, and sports devices. No more than 1 Hz sampling rate (once every second)īMP180 Barometric Pressure Sensor: About BMP180.Good for 0-50☌ temperature readings ☒☌ accuracy.Good for 20-80% humidity readings with 5% accuracy.2.5mA max current use during conversion (while requesting data).The digital signal is fairly easy to read using any microcontroller. Its fairly simple to use, but requires careful timing to grab data. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin. The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. S.N.īMP180 Barometric Pressure Sensor from BoschĭHT11 Humidity & Temperature Sensor: About DHT11 All these components can be purchased from Amazon. The components needed for this project, i.e., IOT Live Weather Station Monitoring Using NodemCU ESP8266 are given below.

Weather stations are also called weather centers, personal weather stations, professional weather stations, home weather stations, weather forecaster, and forecasters.
Weather station sensors may include a thermometer to take temperature readings, a barometer to measure the atmospheric pressure, Hygrometer to measure humidity, rain sensor to measure rainfall, an anemometer to measure wind speed, and more. In this tutorial, we will go for the first one, i.e. There are two types of weather stations, one which is having own sensors and the second type of weather station is where we pull data from the weather station servers. IOT Weather Station with NodeMCU OLED & OpenWeatherMapĪ weather station is a device that collects data related to the weather & environment using different sensors. ESP8266 & BME280 Based Mini Weather StationĢ. You can check this weather station project as well:ġ. The project is very interesting and can be used in remote areas or in a freezer where the data is to be monitored. With the same IP, you can go to any web browser and display the data in a beautiful widget format.

Once the code is uploaded you can find the IP address of NodeMCU in the serial monitor. We will measure humidity, temperature, Barometric pressure, and rainfall and upload the data to a web server. We will interface DHT11 Humidity & Temperature Sensor, BMP180 Barometric Pressure Sensor, and FC37 Rain Sensor with NodeMCU ESP8266-12E Wifi Module.
