Lora Based Wireless Circuit - 2 Modules should Communicate wirelessly - 2km radius

Create an arrangement of 4 slaves ESP32 controlled by one master ESP32 with wireless communication using LoRa protocol. Each slave is connected to a sensor that generates a small positive or negative voltage. The master is connected to a trigger, when the trigger is activated the communication pipe will be open for 2 seconds and the master will read each one of the slaves in a specific order. The Reading: The slaves will be arranged on a straight line that goes slave 1, slave 2, slave 3, and slave 4. When the master is triggered time will be 0s and he will read the measurement of the sensor if the slave 1, then he will read slave 2, then slave 3, and finally slave 4. Then the master will register a new time and read slave 1, slave 2, slave 3, and slave 4. This process of registering...

Hi. I would like to provision a device (node), SX1272, to a gateway, IC880A, and to the server. The server will then send it back to the gateway and to SX1272 to accept the provision, with the SX1272 seeing the message on the UART. This needs to be documented, with the document done in 2 days and the actual provisioning in 4 days. The budget will be 60 USD. I will send you the relevant files if you are interested. Thank you.

Your task will be to help us develop the network of the biometric devices for transferring GPS, Heartrate and Movement data using LoRa. The basic logic would be simply collecting sensors data using microcontrollers and transferring them to a gateway which will be 1-5 Km away (or less if it is the closed farm) from the multiple on-animal devices. The scheme for the current moment is: GPS + Heart rate + Movement → Microcontroller with LoRa, powered from battery + solar panel → LoRa gateway → Webserver → Web- or Android/IOS-app. Tasks: - Schematics - Recommendations of hardware (since the housing will be limited) - Software for the microcontroller ...
