【Tuya Smart】Pet Feeder

Tuya Smart implements smart pet feeder

Developed based on Tuya standard MCU SDK, the MCU is STM32F103C8T6, and the WIFI module is Tuya WR3E

Function Description

• Supports the function of uploading surplus grain status, and the status is obtained by two infrared sensors.
• Supports switch and night light functions, and status supports uploading and issuing.
• On-board buzzer, the buzzer will sound when any operation is issued on the APP and when the infrared sensor detects changes in the status of the remaining grain.
• Supports manual feeding and fast feeding functions, and can manually set the number of feeding portions, supporting 1 and 2 portions. When there is 1 copy, servo 1 works, and when there are 2 copies, servo 1 and servo 2 work at the same time.
• Onboard manual feeding buttons, button 1 and button 2 control the work of servo 1 and servo 2 respectively.

Principle description

• The remaining grain detection consists of two infrared reflection sensors. When the external reflection sensor detects grain, it outputs a high level. When STM32 detects that both sensors are high, the remaining grain is considered to be 100%, and when one is high, it is 50%. , otherwise 0
• The feeding function is implemented by a servo. It has two servos, representing two feeding mechanisms respectively. It can be set to feed 1 or 2 portions in the software.
