Description

Weather and energy monitory system measures parameters like temperature, humidity, heat index, voltage, current and power. I used 16x2 LCD to show the parameters on the device, as well as these parameters are uploaded over the Internet using IoT. Our goal was to design such a system that can be used to monitor energy parameters using IoT.

Details

The aim of this project is to develop such a system that measures the temperature, humidity and energy parameters and upload them on the internet. To measure humidity, temperature and heat index, I used DHT11 sensor, I also used an additional DS18B20 sensor which also measures temperature. NodeMCU is used because it has built-in WiFi module that would be used to upload the data on the internet. For measure AC current and voltages I used a power meter with a current sensor. I also attached an LCD to display the values where the system is installed.

Components

1 × NodeMCU 0.9
1 × 16x2 LCD
1 × DHT11 Thermal Management and Protection / Thermistors
1 × DS18B20 Sensors / Temperature, Thermal
1 × LDR Resistor Networks / Thick Film Networks

Uploading data over the Internet using ThingSpeak

I used ThingSpeak's web servers to upload the sensor's readings over the Internet, since I needed values every minute or so and not every second, so I easily got to use ThingSpeak for free. Here are some sample readings I got:
I'm reading the parameters such as, voltages, LDR value, Humidity and Temperature and can easily be plotted using ThingSpeak.
Tested Sensors with LCD

So, I connected all the sensors on NodeMCU and displayed their data on a 16x2 LCD. In the video below I used lighter on temperature sensor DS18B20 and the effect can be seen on LCD, as the temperature rises from 30 °C to 35 °C. Later I test the LDR sensor by blocking the light and the result can be observed on LCD.
