I have a project to measure dc voltage and current from a generator, previously I used a voltage divider circuit and acs712 sensor for measurements. but the acs measurement results are very bad on the esp32, can this ads1115 module help the esp32 in reading the current measurement results?
Hello friend, I have a question, the LM7805 regulator should not have condensers and heatsinks for the heat generated, in this case I want to connect a brushless motor to measure the current, but I use an Arduino
your code is spot on,. thank you I've tried so many others always an issue. I have the ACHS-7125 only had to change the sensitivity from 0.066 to 0.040
I question this myself. I tried supplying the ACS1115 with 5v and it seems to give the same answers. However, I wonder how long the ESP32 will last with the 5v instead of 3.3v being supplied to the ACS1115. It appears the ACS712 likes 5v, so I understand that. But I wonder if supplying the ACS1115 with 5v is a proper solution. For me, I have this same question.
Hello Sir, can you share a code with esp32+acs712 measuring DC current along with circuit diagram since resistor will be involved due to voltage difference. this value should be seen on blynk or thingspeak. help is appreciated.
i tryed the same circuit and tha same code but i have problem it's giving me values between +12 AMPS and -12 AMPS and keeping up and down between this two values and i know 12 amp the right one , any solution ? @@ElectroRetro
Rather bad solution, you compare score to not acurate clamp meter with only one digit after coma. After ACS you didnt add any rc circuit for filtering noise, you did not increase capacitor on acs pcb, you do not calibrate acs to midle point which flows for this sensor ;) for me it is standard current measurement
Is the voltage going to the gpio pin 5.5v? I thought it had to 3.3. Please let me know . Thanks for the video.
Prosto i ciekawie. Podziwiam

Yes, ads1115 can improve the readings.

How to use it with 50V ? What's the minimum stable current you can measure with it?
You can use it with 50V. The one i am using is 30A version, with it I can measure minimum stable current of 0.100A.
I2C bus at 5V without level shifter?

ESP32 required 3.3V and in coding you used (2.5-adc value)xxx for calculating current value is that correct ? is that 2.5 offset is correct? or 3.3/2?
The acs712 sensor has an output voltage of Vcc x 0.5 = 2.5 at the input current 0A.
Verry good if needed for multiple device, why not just use the analouge pin on esp for 1 light tho?
Both work, however the ADS1115 provides more accuracy (16 bits) than the ESP32 by itself (12 bits).
I need some guidance
Is it obligation to use ads1115 ? Because the esp32 has his own ADC . Please answer me
Esp32 adc is 12bit. Ads1115 is 16bit.

@@ElectroRetro
Are you measuring Ac or Dc current?
@@ElectroRetro Ac
You can measure Ac current with acs712, But this code is for Dc current only.
Is that usb to TTL programer? or usbAsp
USB to TTL
@@ElectroRetro alright thanks sir.
Do you have any video guide on how to use USB to TTL to program esp32?

can i use it without ADS?
Yes
Can it mesure 220V?
It can measure AC current.
What is the simulator software for the schematic
I am using easyeda for circuit diagrams. For simulation you can use proteus.
@@ElectroRetro Is esp 32 available in proteus 8.9.
I think Esp32 is not available in Proteus. There is an online simulator called wokwi. You can use that for Esp32
What is the -2.5 in the calculation value bro
The ACS712 is being supplied 5v. The 2.5v is half of that (zero point).
it is compatible with any version of esp32?
Yes
(volts0 - 1.61)/0.025
Am using WCS 1700
Some minor issues in accuracy.
You have any solution sir ?
I think it's because wcs1700 sensitivity isn't linear.
The sensitivity of wcs1700 change with different current.
Current ac or dc?
Dc
😁👍
Hello are you there I need a help
... please
Yes
@@ElectroRetro bro do you know how to make an ic tester with Arduino
