Its a paddle wheel flowmeter , its using hall effect sensor along with (16X02)lcd . We are looking forward to build a custom module or integrate a module with it (just module no mcu) . The original instrument is powered by 2 X 1.5 VDC Duracell battery & has atmega32 micro controller on board .

What I understood is that signal conditioning is taken care by the existing sensor circuit which is powered over 1.5 VDC batteries. The best way is to run GSM module with its dedicated batteries. And, as per the power reality of 4G module goes. You can try get best out of handling interface (basic to read data) and sending to cloud. Browse quectel's portfolio. If you are in Pune, give a call to Millennium Semiconductor and speak to their FAE to find out which gsm module will serve your needs.

Hello @here, @ZacckOsiemo @Umesh Lokhande @undefined.elf I have been working on the design and implementation of an energy meter. So far, I have been able to read my AC voltage and current successfully using differential amplifiers, calculate the power, and also get my energy in kWh. I am currently working on connecting the device to a server using GPRS, specifically, I am using the sim800C gsm module to do this. I have written the drivers for the UART and tested the sending and receiving functions, i made some pushes to github, here is the link, you can please check it out and let me know your thoughts

The readme is on the main branch, i am just working on a feature so i created a new branch, i will merge when done with this feature

Hey @Event Pings and @Middleware & OS devs,
We're 15 minutes away from the Engineering Hour session on Gesture Recognition with TF Lite and FreeRTOS. You have a couple ways to tune in:
* Livestorm meetup platform (recommended): https://app.livestorm.co/devheads-community/devheads-weekly-office-hours-1
* Discord Engineering Hour stage channel: https://discord.com/channels/1130679493799977062/1212286094830477323

We'll see you in a few.

Great session @ZacckOsiemo , @wafa_ath and @undefined.elf

ZacckOsiemo•12/1/24, 4:29 PM

Thank you @Afuevu

ZacckOsiemo•12/1/24, 4:29 PM

any questions

Afuevu•12/1/24, 4:38 PM

For now no questions, I'm looking forward to next week

Afuevu•12/1/24, 4:46 PM

So I have been working on an energy meter project for some time, I have implemented some nice functionality like voltage and current readings using differential amplifiers. I will be having a session to talk about these things on Wednesday Dec 4, 5 pm WAT. I would appreciate it if you @here were present, here is the link: https://app.livestorm.co/p/5507168f-31d9-45b5-9cf8-242db90bc4d8/live?s=79b27e95-039c-4ba8-8d9e-6be2a64e75c7

I'll be using Ltspice to explain how I went about measuring ac voltage and current using op amp in differential mode

I think it's been recorded to those who missed it

az sum misho•12/1/24, 8:12 PM

hey guys, i will try to make a mini project for motion detection in my room and the temperature. i have a 830 point breadboard, arduino m-m cables and i use ESP-32S
DHT-11 for the temperature sensor and PIR rosfix hc-sr501 for the motion

it will be my first try at anything IOT, any ideas/tips and if its going to work? or i need more things?

Umesh Lokhande•12/2/24, 5:45 AM

Yes, it'll work, and the list of components you have is good enough to get started. Also, there are plenty of videos on YouTube to help you with these generic sensors (interfacing) with ESP32. If you get stuck, feel free to ask for help here with details about the issue you're dealing with. Looking forward to seeing your progress in the project and self-promotion channel!
