Looking for an individual to consult and program a Lora node system. I would like to make sure the data is being sent and received with consistency. The micro-controller that seems to be best would be a esp32. I would like the system to be low-cost. I am open to a professional recommendation. Transceiver: • Collect data from a HX711 ADC every 10 minutes [[login to view URL]] • Be able to run on battery for a long period of time. Receiver: • Collect data from the transceiver. • Send collected data to a google firebase database • Simple way to connect the microcontroller to Wi-Fi without programming for me. Most likely using a cell phone localhost to connect to Wi-Fi. • Will be powered by a wall outlet. This should be a simple program.

Hello, I understand you need to send data collected from analog source to a google database, but I don't see the need to have two nodes in your system to ge the data to a google firebase, you can use ESP32 GSM that can connect directly to google firebase and send your data every 10minutes, however the only advantage having two nodes brings is that the transciever can be optimized to not consume power at all, in case thatsn the situation you're in, I suggest you use 2 esp32 that communicate with ESPNOW a protocol made by ESPRESSIF for low power communication, I have a limit on the number of words I can write here, please contact me to discuss this in further details, I probably can make better suggestions given better detailed specifications. Have a nice day
