Blynk 2.0, Arduino, DHT11 and SIM800L | Send Temperature and Humidity Data to Blynk using GSM Module
Переглядів 8,988
День томуToday, we will learn about how to send temperature and humidity data to new Blynk 2.0 using Arduino UNO, DHT11 and SIM800L GSM Module. In this project, I have used SIM800L GSM Module. I used this because, this project needs internet connectivity to send data to Blynk cloud. and I used the GPRS feature of SIM800L to connect to the Blynk server, and send temperature and humidity data to Blynk cloud.
Parts:
1. Arduino UNO - amzn.to/3ZWKAz2
2. SIM800L - amzn.to/3J48mlW
3. DHT11 Temperature Humidity Sensor - amzn.to/3mJbNqC

@@AhmadLogs Hi. Just an update for this topic, i have successfully connected and sends data to blynk cloud using arduino uno / Sim900 and ACS712 current module. however, it is being disconnected to blynk cloud every 24 hours. Any thought on this? Thanks again.

@@joseneyargonsula732 you will have to write a code that will check periodically, if the internet is connected or not? and If the internet will disconnected then the code will connect again. you will have to add the code in the loop function

how you are able to solve the Cannot Init error. test the DHT Sensor separately, without sim800l. There is some issue with your DHT Sensor wiring.
