    I have a working ESP8266 WiFi with a load cell as my sensor. I need it to work on battery. When i connect the battery, it dies after 1 week. Same for when i use Uno with LoRa. I tried to use the deep sleep function, but its not enough to make the battery last more than 1 week. If you know how to make this work for at least 3 months. please let me know.

    We have an environmental monitoring system which uses an ESP32 controller. It uses i2c protocol to talk to sensors, which is not working reliably enough in a noisy environment, so we'd like to change to RS485/MODBUS. We already have the RS485 sensors. This project is to update our main board schematic and PCB for RS485, as well as updating the firmware to use the new sensors.

    This project involves, WiFi, Webserver,SPIFFS, and Serial communication to a device. How it works: When client connects to esp8266 WiFi (AP mode) and punches the IP of the webserver it opens a webpage that is stored in the SPIFF. When webpage opens it queries the sensor via serial TX for specific reading, then receives the data via RX and then send to the webpage to be displayed. This works gr...
