Can you give instructions on how to make a 2ac 1dc measuring device?

Please how i add heater to this setup & control the temperature by lcd keypad shield buttons ?

The music bro.

Thank you for this, this is the most clear demonstration I have seen. The charts and pin configuration helps a ton. I just wired (soldered) a multiplexer to my nodemcu for a garden monitoring project with multiple soil moisture sensors.

I have a question, I try to connect this module, but it not work. The software can open and it can connect, but i click 'start Measure' button. There are no MSG. It feedback 'failed to read!'. So now how should I do？

where can I get the 3D file to print for this project?

thx for the video. The white wire of the YHDC sensor Vref is not connected ? regards

I'm using an ESP32 I changed the suuply voltage to 3300 and changed FinalRMSCurrent's 1023(arduino's 10 bits) to 4095(ESP's 12 bits) .. both just won't give me accurate metering, on idle I get 1.xxA not 0A like in the arduino. any help would be appreciated.

Can I use it to measure more than 100 amps?

Can I use it to measure more than 100 amps?

I used esp8266 for Pzem017 using this program, but when compiling it there was an error in the serial2 section. Please help with this part

@3:00 what is that usb device for mesure?!? From where to buy it? "Keyweisi"?

Hi man, does it work without battery?!? Meaning inputing into "blue" standard controller both "panel" and "battery" spliting cables from the panel

Can I use a PWM motor speed controller and an amp / watt meter to solar power a peltier device without a battery?

Interesting explanation! Cheers from Australia ❤subbed and liked👍👍👍

Simple question. I want a mobile charging option without battery involved. I have a 60w portable panel and 10 amp mppt controller. Can I just connect the controller to a car cigarette socket and use the usb ports? Will the current be stabilized by the controller and car charger, and would the controller be damaged by not being connected to a battery?

Can for read bidirectional?

is the polarity really required - can i switch live with neutral?

This was great! Thanks for sharing.

Crazy to use a 1000:1000 CT to measure voltage like this. If the balast resistor fails, you fry your circuits. You should safely step down the voltage using a proper voltage transformer.

Bloody piano music 😱

OK... this is cool. Sooo what it's doing is basically acting as a pin swapper for the 16 potential analog pins and routing that pin to the original A0. Problem is 4 pins to control s0-s3 is a lot on an ESP32... However on my breakout board I'm making I have a dedicated 16 port expander so could nick 4 of these to control s0-s3. Other option is a dedicated SPI 8 channel ADC with 16 or 24 bit resolution which is especially good if already using SPI as it's just 1 pin for the CS.

hi, firstly great video. i need help with how exactly should i measure the ac current without the help of arduino. At Vout we do get some voltage how exactly to validate it according to the current. please do help thanks in advance

In your tutorial guide you said the following "For people out there that do not have the LCD Display Shield, you can manually offset by entering the offset value in the code and re-upload again. There are 2 offset values (voltageOffset1 & voltageOffset2) need to calibrate." what values do i need to hardcode in the sketch before and after turning off AC power supply ? Can you please explain this is very urgent.

It works!Thanks a lot for this

Is it necessary to keep the 50k potentiometer in the circuit board after calibration? Thank !

I got one of the 50A transformers and I'm not convinced that these are accurate. To test I connected it to the house's main ground wire & switched on the kettle (2000w). Before switching on the kettle the reading was +- 6.4A, and while the kettle was on, it shot up to +-46A which can't be right. From my calculation the kettle should be drawing around 8.7A (2000W/230V=8.7A). Does this look right to you? Thanks for the video

cool very good one question it will change and show on the LCD from 0 to 250v

Thanks very much for this video. With your help I have managed to get a modified version of your sketches working on a Clone Nano using Softwareserial and your modified Modbusmaster library. My plan is to use the 2 x PZEM016 to measure solar generated power and load power. Subtracting one from the other I can get grid import/export power. By using a software PID controller (part of Nano sketch) with a fixed power setpoint of zero, I can automatically adjust the battery charging rate to achieve zero grid import or export where possible during daylight hours whilst keeping the battery topped up as much as possible. This should reduce my utility bill. Thanks again for your help. Your videos and write ups are very clear and useful. Keep up the good work!

Hello. Is there any way to measure up to 260VAC? 250 is just a little bit too small in my case. Any ideas?

if we are using 3 of these, can we connect the reference cable all to the same analog pin?

Very informative information Sir, can I use the control motor module for charging lithium batter? because it very convenient to adjust the voltage

Anyone know where to find ATtiny85 code? Please and thank you. For DC current.

nice

What if I have 100watt panel with vmp 18 volts. What do I do be able to use it for phone charging?

You just made my day. Thanks.

very cool!

Sound is not clear

Thanks for the great video. Will this have bi-directional capabilities? For example, will the PZEM-016 (AC) be able to measure when I am consuming or feeding energy to the grid?

Hello sir, can i use this with Hall Split core Current Sensor SCT013?

Where can I find connectors compatible with the RockPals portable solar panel and pump wires

Thanks for this video! For the low end amperage (10A version), what is the lowest amperage you can read? You mentioned in your article for the 50A version, if it dips below 0.5A...then it will set the ADC value to 0. For the 10A edition, does it push the threshold lower? Can you measure current such as 0.25A or 0.10A? Looking at all the datasheets that I can find on this sensor, I cannot see this value documented. Again, thanks for sharing this with your detailed right up. Seems there is not much on the market in regards to low current (mA) DC current sensors and measuring in general.

sir, thanks for sharing, but when Current DC 0A lcd show 1.8A, not 0A but, when we measure upper 1.3A, it will measure good enough

do you have the Arduino program for this, mate?

Did someone has ESPHome running with that sensor and can share code please?

Can this concept/idea for 3 phase ac real time monitoring application that consists voltage, current, pf & freq, adding rms value & angle..is it must use 3 nodemcu to mix in one blynk interface to monitor each phase simultaneously?thanks in advance..

Спасибо, хороший человек. Я смог подключить PZEM 017 !!

what size battery do you recommend, what is the size of the battery in your diagram?

Can we use this module with dc motor
