CPU Environment: Arm Cortex M4 - Hope RF LORA6601 integrated CPU and LORA transceiver. Monitor 5 I/O pins - to determine if a switch contact is open or closed (this may be an analog resistance measurement - I will define threshold of open and closed in ohms) Closed is Good, open is alarm condition Contacts check 1/15 seconds, or allow a variable set during compile so we can test different values. Also use A/D to drive an LM84T temperature sensor and measure once per minute (variable so we can play with different time periods of how often we check) Also - possibly a simple interrrupt if 75C is exceeded Alarm condition if temperature is over 75C once per 5 minutes - (this is a 'status ok' message) When alarm conditions occur (contact open or temperature >75C) alarm messa...
This project includes the upgrading and renovation of the existing Lora Street Light infrastructure. I am looking for experienced professionals to make energy efficient improvements to the existing infrastructure in a timeline of less than 6 months. During this time, contractors should be able to achieve aesthetic improvements and heightened safety and security for the surrounding space. This project requires careful planning and management to succeed, and I am looking for professionals who have the skill and expertise to do so. The goal of this renovation and upgrading project is to ultimately create a smarter and more secure environment that also starts to make strides towards a more energy efficient future.

Please, web developers do not send me your offers. Only embedded 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 ha...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 increasing the range and the number of nodes (eg ESP32+Lora) please let me know your thoughts and a price for this. Of course in such a case, the deadline will change as well (...

A device that transmit and receive encrypted messages using esp-idf send through lora module by connecting wifi tcp with a mobile app
Hello, I have a project that I need completed ASAP (12-24 hours) and wondering if you have any interest. Code: (Code here acts as a middleman between LoRa gateways running Semtech packet forwarders and servers ingesting packet forwarder data.) The code sends packets to ALL gateways. What I am looking for: I want to include logic in that can handle routing packets to backends based on a defined set of rules. The rules can be in any format but one thought was using JSON. The rules will be - weight (how often a gateway is sent a packet) - rssi (what value RSSI is sent to the gateway) - allow/deny (what gateways are allowed to be sent packets) If you would like to do this let me know! As I mentioned I have a deadline.

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.

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...
