After reading all the inputs, i guess i'll consider the ESP alternative. I also got feedback on other fora that RF might also be a good option to consider. Now knowing that price also can be lot lower if procured from the right place, there's more motivation to consider other options. Quite an...
Audio link sounds interesting. First thoughts are that we'd need ADC and DAC both (for two way comms), and transducers themselves only generate a single tone, no? The one of their resonating frequency?
That was a lot of helpful information Brian, especially not knowing the detailed specs of how RFID works at electronics level. Indeed feels like this won't fly off with RFID. The WiFi link was an option I had considered, but wasn't sure of the price. I'll look into it further and see if...
Hello everyone,
I'm working on a project to communicate between two boards OTA (over-the-air) but within close proximity. I could consider LED/laser based communication, but that is too directional. WiFi or BT are wireless, but using them increases the BoM cost. I considered NFC/RFID, but all...
Here's the code and the output. I made a new clean ADE board and that is also giving the same trouble. After the first few readings, the Irms and Vrms values are reported the same. This, without any AC load/connection connected :(
#include <SPI.h>
//#include <SoftwareSerial.h>
const char...
My apologies @wwfeldman, and thanks for your reply as well. I indeed forgot to upload the schematic. Same is attached now.
I am indeed using the board for AC power measurement. Infact we're actually building a product in itself for some specific purpose, but we're unable to get stable correct...
Hello Experts!
Calling out for help again while I'm in difficulty.
I'm working on a power meter setup using the ADE7763 and finding it difficult to get the correct Vrms, Vpeak, Irms, Ipeak values from the chip. I am using the attached schematic where R7+R6 = 510K, R8 = 1k. R12 and R13 are 8.8...
I suspect there's a thermal conductive adhesive on the Protocentral breakout board.
I did read that the EP has to be connected to ground. That being the case, I might as well solder a metal plate EP and use that as an elevated probe and connect it to ground as well. With metal soldering, the...
Hello there,
I'm working on a PoC prototype for a human/animal body temperature measurement system as an IoT solution. After some research, I see that the MAX30205 is an excellent choice for human body temperature measurement.
Now I ordered the sensors alright, but I'm stuck on one question...
@KlausST - I'll try with the diode anyway as a start to simplify things and assess the impact.
@dick_freebird - output of the controller is unregulated and not fix whereas the battery is an LFP one. As I understand, and from some damaging experience, that I cannot just let unregulated voltage...
@KlausST - forgot to mention that the operating range is just about 42-52V. So 0.7V is also still 7%. That's a lot of juice wasted in an e-bike situation, hence trying to find the most optimised solution. Any diode seems to be having
@d123 - this time its in the discharge path, so higher...
Experts!
Need help in continuation of a circuit I was working on, for which I had great inputs from the community. This was the original post:
https://www.edaboard.com/showthread.php?380027-MOSFET-switchover-for-E-Bike-controller
Referring to the above, I had managed to get a LFP battery with...
Thanks @KlausST and @c_mitra for clarifying. Things seem to be a little clearer now. I'll take it from here and continue with my design. I have to admit that this forum has helped me lot more than some of the other fora. I'm getting fonder of this forum. Hope I don't trouble you guys too much...
Thanks @KlausST for clarification.
So to put it differently, how can I determine/compute probably from the specs or some other parameters, how much minimum current needs to be supplied to a motor for a given load? For the purpose of this discussion, the load on the motor is maximum rated load...
Experts! My sincere apologies if this post is misplaced for this category. I didn't find any other appropriate one to post it in.
My understanding of Motors - AC or DC, Brushed or Brushless - is extremely limited. My query is related specifically to a Brushless DC Motor used in an Electric...
