Remote-Relay-with-Battery-Monitor
Progress is good on project; mostly complete, want to add two-way messaging, that will come later. Now the project uses two, EByte E220-900T30D transceivers to wake a sleeping ESP32; first a WOR preamble message. Next when a person sends a URL request to view camera; the solar charged, battery power is switched on with a MOSFET, KY002S switch. Happening at same time a countdown timer is started to turn off battery power when timer expires. When battery power is turned on; battery status is checked using a INA226 battery monitor module. Battery data is logged to a file. Accessing log file is accomplished by a stand-alone FTP sketch to allow access for viewing battery data file. Camera is a Wyse Cam v3 that draws 180 mA; that until now used battery 24/7 on a 10,000 mAH power bank that only lasted about day. This improvement; should conserve the majority of lost battery power; since camera will now only be on by URL request and on-time limited.
Suggest labeling transceivers; one "Sender" and the other "Receiver".
