Humidity and Temperature Firmware

This is the firmware that will be flashed on esp8266 mcu and that will be reading the temperature and humidity

Note because of demonstration purposes the firmware is set to send the humidity and the temperature after every 1 second but In real scenarios we will set the firmware to send data after 30 minutes and average for the whole week or whole day

Setup

Requirements

• esp8266 mcu (or any other arv mcu provided that it can access the internet) like the one below
• A breadboard
• Jumper cables
• DHT11 humidity and temperature sensor
• A usb cable for powering the mcu

Instructions(Hardware)

• Mount the mcu on the board at the center
• Mount the DHT11 humidity and temperature sensor on the bread board
• Take one of the gpio pins and connect it to the data terminal on the dht11 sensor
• Connect the voltage(3.3v) pin to the the vcc terminal on the dht11 sensor
• Connect the esp8266 ground(GND) to the dht11 sensor ground
• Connect the cable to any power source

Instructions(Software)

Make sure you have the following:

• PlatformIO or Arduino IDE with esp8266 Adafruit capability for compiling
• esptool for flashing
• And a data cable for connection your computer with the board
• I would advise you to install PlatformIO extension on vscode Clone the project from github

git clone [email protected]:aitumik/firmware.git && cd firmware

Change the following in your code

String ssid = "your ssid";
String password = "your password";

Build the project

pio run --target upload

Now if the API is up and running either on the same network with the firmware or just a remote server that the firmware can reach, then you should be able to receive requests from the mcu

Libraries

DHT-sensor-library by adafruit

Future features

• Add the ability to compress the json being sent to the server to save on memory
• Allow for authenticated requests to be sent to and from the server
