Abdominal breathing training trainer

Abdominal breathing training is a good way to help you get started with physical and mental exercise. However, the more people want to be quiet when practicing, the conscious thoughts will easily wander away, and the breathing exercise process will be interrupted from time to time. This design aims to develop an auxiliary electronic device to It will be very helpful and practical to guide and monitor practitioners in real-time to carry out scientific and reasonable breathing movements.

The design is based on the SensorTile.Box kit. It is set to expert mode for direction change detection (using a gyroscope), close to the practitioner's lower abdomen, and uses the internal gyroscope to sense the ups and downs of the abdomen during breathing in real time, and then uses a self-made auxiliary The circuit module collects the LED flash signal when it exceeds the set threshold and transmits it to the central main control circuit through wireless transmission; the LIS25BA bone conduction sensor collects and identifies the vibration signal of the user's breathing status at the nostrils, and the signal output is also connected to The central main control circuit is responsible for monitoring the optimal compliance of the breathing process during the entire exercise process, and the corresponding voice prompt information broadcast is made by the central main control circuit.
