Code Sketch
https://github.com/jdetka/arduino_sensors/blob/main/DHT-11_FC-37_PCF8523_Sleep_RTC_vers.1.1_010121.i
Code for Arduino R3 Uno plant disease ecology sensor. First code version. Works with DHT-11 temp/rh sensor and FC-37 rain sensor. Key accomplishments. Toggles on/off the rain sensor to save power and reduce heat and corrosion of sampling surface. Integrates Adafruit's SD card shield for RTC timestamping and storage to onboard SD card. Next steps, - Assess power consumption. - Add code to turn off lights on R3 Uno during rest period. - connect to solar powered lithium battery source and build a case.
