Introduction:
Goal: Conserve battery power for a Wyse Cam3 video camera that has a current draw 180 mA at 5 volts. Camera viewing is web based and has a very low demand to view camera; less than five views per day. Using a remote switch controlled by Async Web Server request will prevent battery draining power twenty-four hours a day. Currently a 10,000-mA battery bank only lasts a day.
Overview of the Project:
E220 Remote Switch project will reduce battery consumption by utilizing a countdown timer; started upon web request, turned off, on countdown timer expiration. When web request is severed the E220-900T30D Sender module will send a wake-on-radio (WOR) message. Receiver E220 module wakens from the Sleep Mode. Sleep Mode is an ultra-low current state in the microamp range. ESP32 will wake from Deep Sleep and turn on battery power; at the same time the E220 module receives the WOR message. When countdown timer has expired; E220 Sener module will send a message, switching battery power off and putting the ESP32 into deep sleep and put the receiving E220 module into sleep mode. Cycle repeats on new web request.
E220-Remote-Switch project has been updated to include E220 Sleep Mode; reducing always on current comsumption to microamp range!
