IoT Raspberry Pi Smart Container with Email Alert and Web Monitoring
July 24, 2019 - 5:18pm

Hello,

I need some help for the project https://circuitdigest.com/microcontroller-projects/iot-raspberry-pi-smart-container

I have successfully connected the connection and even code works perfectly, i think. But the weight sensor is not reading the weight but gives an output with random numbers and exits. Can anyone help me, please? My mail id would be snehamane81@gmail.com:Awaiting for your help and reply. Kindly please do the needful. Thanks in Advance

Have a nice day.

The sensor used in that project is a HX711 Load cell with an Amplifier Module. If you are not getting proper values form the sensor it is probably because you have connected it wrong or it is not calibrated at all. You should have followed the below article to interface it properly with pi before expecting it to work properly

Also you simply cant give your E-mail ID on a forum and ask people to send the answer to your inbox. Forums dont work that way!!!

All the best...

For getting you project work, use basic programming rule here to divide and conquer ;). Here first of all before coding the final code your project, just try to connect only sensor with your raspberry pi, configure it with built-in terminal to show values. Then place some weight on the sensor and check if readings are appearing in the terminal window. Take a record of these readings if these are appearing. If readings are not appearing, then you have to check the sensor side all the characteristics like pin-out configurations, input voltage, current ratings, threshold voltage and values chart against weights values. I think, there might be an issue at sensor's side, as you said that you made connections according to the tutorial. Here I recommend you to contact the SSLA technical support team, for getting better assistance regarding your project.
