First of all, please the software developers don't send me offers as my project has not so much to do with html, css, etc at this stage. So do not waste your time and my time as well, please. I am searching some hardware engineer with real experience in setting up a network of a lot of nodes (esp32 or esp32-Lora) I want to set up a network of 120 nodes in a field (open air) where the most distant nodes are around 120m from the pc. All the rest in between nodes have a distance of 3-4 meters each one of its next one. They are deployed in 4-5 lines of around 25 nodes each line. I have already set up my senders and receiver sketches (Arduino IDE). The matter is the limitation that the ESP-Now protocol sets (up to 20 nodes as I know). One solution that I thought is to make 6-7 c...
Rasberry Pi tells main controller (currently a pico) to turn 4 winches on. The main controller signals via LoRa to 4 winch controllers to turn on for 1.5 seconds. There is an anemometer that needs to be connected to the Rasberry Pi, and if the wind speed is above X, the winch command is halted. Your scope of work = 1. Write the programming for the Rasberry Pi. (We will load it here in Oregon, USA) 2. Update/Improve/Rewrite to your preference, the Python scripts between the controllers. (We will load the controller scripts here in Oregon, USA) Background send a proposal that let's us know you read this. We have the hardware - relays, buck converters, transceivers, Rasberry Pi, LoRa devices, anemometer - we do not have good documentation of the plan, yet
Let suppose we want 120 esp32 in a mesh structure. Every node (ESP32) has a distance of 4 meters each other. The longest distance (node) is 150 meters from our PC. The physical structure of the devices is in 4-5 lines of 25-30 nodes for example. In our PC I want to have a webpage where I can ...(120 EPS32 devices-nodes) work in deep sleep mode when their button is not pressed. Even the page is closed, when we open it back again, the data is preserved (running PHP-mySQL). I want to ask if such a project is possible to be done, secondly we need a router (internet) ? Also how reliable could be? Do we need Lora or the ESP32 WiFi feature is reliable enough given a mesh structure (obviously chain mesh structure). Please, only freelancers with experience in such projects (esp32, Lora...

Brief description: - Make communication between Slave and Master devices via LoRa protocol. Master device have built in web server that contain 3 states of slave device inputs and have 3 buttons for control 3 relays. More advanced design will have android application, read 3 states and 3 buttons for control 3 relays. Slave device is Ai Thinker Ra-08h (Its chip ASR6601 is a universal LPWAN wireless communication SOC, integrated with RF transceivers 868MHz, modems, and a 32-bit RISC MCU). I buy this chip because compact design and small size. Small size is most important in this project. Slave device need to control 3 signal relays and to read state of 3 inputs (solid state relay contacts). Slave device will be powered constantly and no need for power saving features (sleep, standby...
I have written a driver for the SX1279 however there is an issue with the transmit sequence that I could use another set of eyes on. If you have experience with the SX1276/77/78/79 family that would be fantastic. I am thinking it is probably I have just set a bit wrong somewhere but I have started at it too long with no luck.
As already agreed with Lora, I create this project for the Swiss FHS poster.

Initial set up of a Multitech outdoor gateway, provisioned on an ethernet connection running on the Sennet network, processing on the edge provided by Losant. We are using MOKO pro trackers. Need help with the final touches. MOKO's report GPS coordinates but do not update location on map. We are also looking for a push notification from Senet's application server upon detection of movement. This project was funded under a small grant and is being executed in conjunction with the U of Maryland and Maryland sea Grant. This is just an initial foray into this technology to try and ascertain whether this is the appropriate communication technology for some conceptual future projects.

...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...

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...

...activates a 12vDC motor to lift the door, and activate a red/green light if access is granted. However, I am also wanting to use a LoRa (sx1278) module to provide inputs. I want to put a Hall effect sensor on my fence gate so the dog door knows if the gate is open or closed, and if the gate is open, I want the dog door to not open and flash a red LED. That’s the bulk of the electronics, but I also want some safety features like an IR sensor so if the dog or my kid are in the doorway it won’t close, and resistance monitoring on the motor so the door reverses direction if it gets blocked. And momentary switches on the door so it stops at the end of travel. I have 2 LoRa modules (sx1278) with antennas 1 L298N motor driver, I planned to have one side power the door...
