Power Consumption Too High #1

Open brainwater opened 1 year ago

brainwater commented 1 year ago

I'm using an ESP32-S3 qt py with a BME280 sensor. With a solar panel charging the 350mAh battery, once it gets dark it only lasts for less than 2 hours. Measuring the power draw with my multimeter it was using ~20-50 mA, but online I'm seeing the expected power consumption of the esp32-s3 at around 100+mA. I'd like to have the battery last through the night.

If I could wake on when the rain gauge flips, I could use sleep or deep sleep. I may need to use the raspberry pi Pico for that.

I could also use LoRa instead of wifi for reducing power usage too, but that adds complexity of another controller or computer needed to bridge between LoRa and Wifi. Could I connect the microcontroller to zigbee instead? What about matter/thread?
