El proyecto consiste en la monitorización de una planta fotovoltaica de autoconsumo. Se deben capturar los datos de máximo 5 variables del Inversor Sungrow por el canal de wifi y enviarlos a un servidor Cloud mediante una API. Hemos pensado en un equipo ESP32 con wifi y ethernet o con una Raspberry PI It is important to know the Grafana monitoring platform

Necesito un app que me permita conectarme a un esp32 mediente bluetooth 1.- mostrar el directorio de la SD (Carpetas ,sub carpetas y sus archivos ) 2.- poder eliminar , y agregar archivos - 3.- No debe permitir abrir el archivo 4,.- para poder agregar un archivo debe de aber un boton que inidique , agregar archivo , al dar clic abrir el directorio de arduino y solo permitira agregar archivos con terminanciones .smt (algo como cuando enviamos fotos por whatsaap y se abre un directorio , aca es lo mismo ) 5.- Al selecionar el archivo se dar clic en enviar y el monitor serial del esp32 tiene que salir el mensaje de Recibiendo datos y trasferencia completada

I need a PCB design to be used for manufacturing. I need it to be 40mm * 16.5 mm. A thickness of 1.5 mm maximum, though I prefer the thickness to be as low as possible to save money as long as it meets re...the chip would also send over the value of the voltage it gets from the battery so I can figure out when the battery is too low and needs to be replaced. Just a note I will not be using an on chip MCU. Lastly, as mentioned, I am wondering if there is a scenario in which I don't need to use HX711. Here's my reasoning: The Bluetooth chip ATBTLC1000A, has two pins called "configurable mixed-signal GPIO" ; they are pins 17 and 18. Since they accept Analog data, I was wondering if I could just directly connect it to my Wheatstone bridge and skip using HX711. Will ...

Hi, My hardware: ESP32 with an I2S microphone ICS-43434 connected. I have a firmware1 for ESP32 which records sound in very bad quality. So the microphone is not compatible with the driver in this firmware. I have another firmware2 which records sound from the same microphone in very good quality. So this I2S driver works perfect from firmware2. I need to get firmware1 running with good sound quality recording. And hope you can do that for me. Here is firmware1: And firmware2 (with good sound): I think the problematic file in firmware one is this:

The thermometer is is a Fine Offset WH2/FT007TH. In order to offload the ESP32 it might be better to use a integrated receiver like RFM69 or CC1101 instead of RXB6 simple superheterodyne receiver. However if the ESP32-C3 has enough power for all tasks, the RXB6 will be fine too. The wireless protocol is documented here: Data needed from sensor: -Sensor ID (1-8) -Temperature in celcius with decimal -Humidity Defined variables: -SSID -Password -HTTP_POST_URL -API_KEY When packet with valid CRC is received: -Make HTTPS POST: key=test&ch=channel&tmp=temperature&hum=humidity -Implement timeout for HTTPS POST (so it will not hang if internet is offline) -Print received data to terminal with result for HTTP POST (OK/ERROR) Code

I have 4 meter devices that will be placed at a water well. They communicate using RS485 MODBUS. I need to use an ESP32 and RS485 Max to collect data in real time to send to a database so the information can be seen on a website. The website will consist of my business website which will be an access point to water companies who login to view their data. I will need an admin to create new customer/water company accounts and assign admins to the companies along with the ability to add devices for new well sites. I will need to be able to add company logos to their pages for customization. The company pages will need admin logins and user logins. Each company may have as few as 1 well site or as many as 100s of well sites. Company admins will need to be able to assign users to well s...

Hi i want to communicate between multiple slaves with single master with esp32 arduino

Hi Dean E., I noticed you planned on adding a design for my solar charging contest. Most designs i got from others have big flaws or are just copies from chatGPT. So I came up with my own design and hope you can evaluate it and build it together with me? I have already done most of the component research. I just need someone who knows what he is doing because i am just a hobbyist. Can you help me with that and you will get the 50USD from the contest. Is that Okay for you?

...engineers that have experience in ESP32 and ESP-Now protocol. I have made a network of many ESP32 devices which send a few data to a receiver-webserver (STA mode). So let suppose we have n number of senders and one only receiver-webserver with name "x". What I want is to increase the range. What I thought as a solution is to put between the n senders and the receiver "x" another ESP32 device that will act as receiver-sender. It will receive the data from all the n senders and immediately will send this data to the receiver-webserver "x". Only 1 day committed engineers to finish the job. The range and the limited number of nodes (20) are the most important "cos" of the ESP-Now. If you have any other solution for increas...
