Call for submissions | IoT smart feeder

Overview

This work is an IoT pet feeder, which can feed cats and dogs. The brushless DC motor is started by controlling the Tuya platform APP. The core chip is STM32G070RBT6, a small chip that meets the functions. The temperature and humidity functions are displayed on the OLED screen and APP. Feeding can be controlled by remote and on-site buttons. In addition, the water pump can be controlled by remote control relay closure to feed water to pets. The module is connected to the motherboard pin header in a plug-in manner, which is convenient for debugging or replacing the module.
1. STM32G070RBT6 main control
2. WB3S Tuya wilf module is connected to the router
3. Based on the APP device in smart life, fast feeding, manual feeding, water pump switch, real-time temperature and humidity values, timed feeding, etc.
4. Control feeding nearby, key1 main interface displays the IoT solicitation order LiChuang EDA, key2 controls the motor feeding OLED to display feeding, key3 stops feeding and displays waiting for feeding, key4 displays year, hour, minute, second, week, key5 displays temperature and humidity.
5. The power supply can be 5V lithium battery or USB port.
