...measurement in oil industry. Once these are released, they come onto the surface. It can take a day or two before the mother ship comes back to collect the buoys. The buoys are to be tracked by the mother ship for these one or two days so that it can effectively come to the location to collect the buoys. 3. Plan : A. The buoys are to have a GPS (preferably IRNSS ) receiver and transmit that data over LoRa. The GPS location will be sent only after the GPS accuracy reaches 20m or after 2 minutes (after reception of first GPS signal), whichever is earlier. The data will have four parts - Buoy's ID (customisable 3 digit numeric ID), GPS location, GPS accuracy and Battery life. B. The transmission has to be initiated only when an inbuilt accelerometer indicates that the buoys...

I have an arduino Mega and an ESP32 Pico in my project. I have multiple variables (around 300) in my arduino mega. These are a mix Boolean, Int and double. I want to transmit these variable from the Mega to ESP32 for some processing and transmit them back from ESP32 to Mega as well. The ESP32 and MEGA are connected via Serial3 (RS485) of Mega and Serial2 (RS485)of ESP32. Currently i am able to communicate between the 2 but the issue is that i am unable to segregate the data in independant variables and rather sending as serial data which is very difficult to distinguish and hence multiple checks are to be done back and forth to identify the data and the variable. I want to create a small library for me which i can use in such a way as below: MEGA CODE:_...
...screen in an Android app. I need an example (to see if I can expand it, if it works well) of controlling 3 Arduino devices, each one with 2 pins to be "watched" and an Android app with 3 graphic panels. Each panel will have 2 graphics LEDs (each LED for each PIN) that will be ON if pin is "closed" and OFF if pin is "opened" (meaning if button is pressed or not). The Arduino device I prefer is ESP32, but you can recommend any other that will do the job. The Arduino devices are 10miles away of each other, so they don't share the same Wi-Fi network. Also, the user of the app will be connected to a different network. Android app code (schematics) and the apk file, Arduino electronics diagram and Arduino code will be the things you will deliver...

I want to use Raspberry Pi Pico to connect to 3 sensors at the same time. The sensors uses 2 sets of UART TX/RX and 1 SPI. At the same time, pico is connected to a computer using usb. Requirements: 1. receive data from all UART, print the data with a given delay. e.g. one with 1 sec delay, the other with 2 sec delay. 2. receive data from SPI (SCL/SDA), print the data with a given delay. 3....delay. 2. receive data from SPI (SCL/SDA), print the data with a given delay. 3. receive input from computer via USB serial, and forward the input to a designated UART TX pin. 4. above operations can be done in parallel without interfering each other, meaning each sensor can work independently. 5. Utilising multicore To carry out the task, you must have Raspberry Pi Pico or similar hardware (e.g. ...
I'm trying to build a project to measure 240v AC electricity at our grid connected, PV assisted home, and switch applicances on and off depending on excess PV generation. I have nodemcu and esp32 modules. I'm only learning arduino coding and am brand new to Blynk, but think these two will fulfil the project. I'm looking for someone who is experienced in arduino + blynk to help me set this up. Please share me a couple of screenshots of something similar that you have done, to prove that you understand more than I do:)

Commercial project with the use of esp32 and mq gas sensors to prevent leaks. Well, the idea of this stage of the project is precisely to develop the source code to run on esp32 where in a certain amount of gas detected it will alarm a buzzer, otherwise it will be connected to Firebase - Firestore where it will be sending this parameter, together as a wifi manager so that it is possible to enter the wifi credentials of the person who buys the device independently and precisely so that I can pull this data and display it through an application in FlutterFlow. In short, my intention in this project is to develop the source code and prepare the database there in Firestore where I want it to have a structure that is commercial, for example: The person who buys logs into my ap...

The current project proposes to explore an alternative localization system based on WiFi or LoRa either as a standalone system for localization or offer a correction to the existing GPS system. The scope of the proposal includes - Explore the feasibility of a standalone WiFi or LoRa system for high accuracy triangulation within a given bounding area. Accuracy in the order of 10 to 30 cms Transform a given triangulation to a map localization for a base station in any polygon (4 base stations +) Explore alternatives including WiFi or LoRa, and Bluetooth BLE for triangulation and error detection to aid GPS localization. Develop a Proof of Concept system to demonstrate the capability.
We want to use a ESP32 Arduino () with 2x Linear Technology ADCs (which has an SPI interface). We're looking for someone to connect us the 2 ADC chips to the ESP32 and read out the data. The data should be sent to a PC using the Serial Monitor in the Arduino environment. The software should also set the output voltage from the onboard DAC to 1.5V. We need you - to buy 2 ADC chips and the ESP32 board (total cost $50) - solder the ADC chip onto a breakout board or similar to allow it to be connected - add a potentiometer for testing - make the correct connections - develop the code so the 2 ADCs can be read independently. WE DON"T JUST WANT SOMEONE WHO SENDS US SOFTWARE!! It's important to us that you demo the actual ADCs working with the board
Deadlin...framework called FLoRa is a simulation for carrying out end-to-end for LoRaWAN network. It has some examples that can be implemented based on the OMNeT++ network simulator and components from the INET framework as well. FLoRa allows the creation of LoRa networks with modules for LoRa nodes, gateway(s) and a network server. See the document attached: The simulation must calculate the statistics results of energy consumption of the LoRaNode and packet delivery ratio. In addition of this, later in C&D stages (Next task) when we increase the number of LoRa Nods, we need to add calculate packet collision ration and capture effect. With a progress report illustrates and elaborate all the steps of the project from A to Z. This framework (FLoRa) needs to be modi...
