Sir i want to design iot based current voltage and power measurements how to do this project
for this also the same bro
instead of lm35 sensor collecting data and uploading it to cloud here ammeter voltmeter are used to collect data (replacing the sensor with meters respectively )and same the data can be uploaded to cloud not big change in code
Your system will require multiple analog sensors. Since the Bolt WiFi module only allows 1 analog sensor, you will first need to interface these sensors to an Arduino and then interface the Arduino with the Bolt WiFi module.
Here is an energy metering project built around an Arduino.
Here is an example on how you can interface an Arduino to the Bolt WiFi module>
You will need to put in a bit of an effort to combine the 2.
But it is not working. I have tried the same as we have tried earlier as temperature monitoring system. I tried connecting ACS712 sensor, in that A0 pin is used to display the data by plotting the graph.
But it is displaying as 1024 in graph instead of Amperes. How to change the code???
Any way to change it???
