In the earlier tutorial we discussed how to setup AWS IOT for an Amazon user account. Now lets see how to use the Arduino esp32 AWS IOT library to communicate with AWS server.
Contents
AWS IOT for ESP32
Download the AWS IOT library for Arduino ESP32 from this link.
Now open the first example pubSubTest.ino as shown below.
.
Wifi SSID and Host Address Configuration
Configure the below parameters at the beginning of the sketch as shown in the image.
WIFI_SSID
WIFI_PASSWORD
HOST_ADDRESS
CLIENT_ID
TOPIC_NAME
AWS Certificate Configuration
The below certificate and private key needs to be copied to aws_iot_certificate.c file in the form of array.
aws-root-ca.pem certificate.pem.crt private.pem.key
Upload the sketch and verify the output
Publish and subscribe(received) messages printed on terminal.
Published message viewed on MQTT Fx client software:
Publish a message from MQTT Fx Client and verify the received message on terminal.
Logging Temperature and Humidity using DHT11 sensor
After setting the AWS client and AWS IOT lib, lets log the real time temperature and humidity using DHT11 sensor.
Install the Adafruit DHT11 sensor library using Arduino Library Manager or download it from this link.
Do the connection as shown below.
Now copy paste the below code and configure the Wifi SSID, Host Address and upload the sketch.
Temp and Humidity logged to AWS IOT server.
Download
Download the Arduino ESP32 AWS IOT lib and examples form this link.
Kindly check our latest AWS IoT libraries, with additional features such as:
1. Device provisioning.
2. Shadow updates.
3. Jobs management.
4. Over-the-Air (OTA) updates.
5. Mobile app for aws
Additionally, you can explore libraries tailored for various platforms such as Azure, Thingsboard, and Kaa IoT, supporting both WiFi and cellular-based applications.
