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 [] • 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.

They are a mandatory feature for deploying LoRa devices in South Korea but I couldn't get any info online. Korean radio waves act requires the RF strength to be lower than -65dBM in 917~923.5Mhz before transmitting. - I could buy schematics of SX1262 at 915Mhz. The reference designs released by Semtech seems to have a lot of unnecessary parts. - Your Experiences and tips on working with SX1262 I'll be looking forward to your reply I don't have any idea of your price so I just set it to low...
