Automatic fish feeder

This low-power automatic fish feeder is made using the Hezhou AIR001 chip. Standby power consumption: 0.8mA (screen off); Standby power consumption: 4.7mA (screen on); Power consumption during feeding: 24mA. Features: 1) Powered by a single 18650 lithium battery (2000mAh), theoretically lasting over two months. A charging reminder is provided when the battery voltage drops below 3.0V. 2) Provided the container contains more food than needed for a single feeding, the amount of food fed remains consistent with each feeding action, avoiding situations where a large amount is fed when the container is full or a small amount is fed when the container is empty. 3) Includes an OLED display, which can be turned off. Display information includes: A) Remaining time before the next feeding, B) Feed amount per feeding, C) Remaining battery power, and D) Other programmable displays. 4) Arduino programming interface for easy DIY. 5) Equipped with temperature detection. When the temperature is below 10℃ or above 30℃, the feeding interval of the fish feeder will be extended to 24 hours (can be programmed and adjusted by the user).
