The chip can also turn off the module by software, and the standby current is close to zero, so that the power supply can always be maintained..
The standard I2C compatible communication interface can transmit the collected data to A-rduino, KL25Z and other microcontrollers for heart rate and blood oxygen calculation..
4WDKING Rechargeable Electrical Air Purifying, Reusable Portable Air Purifier with HEPA Filter for Sleeping Outdoor Sports Housework
...️[Smirson Personal Air Purifier Necklace] built-in negative ion generator]The air ionizer generates negative ions, which can activate oxygen molecules in the air, and combine with positive ions in the air to sink into the ground, so that the lungs increase oxygen intake, remove more carbon dioxide, and can remove secondary hand smoke, Oil fume and other particulate matter. Effectively refreshes the air.Portable air purifiers are ideal for teenager(Age 11-18 years old), adults.
⛳️[Powerful function and easy to carry]Just hang our Smirson Rechargeable Air Purifier.

PROMOTES HEALING: Why Hydrocolloid? Hydrocolloid dressings produce a cohesive gel when it comes into contact with wound exudate to provide a moist wound healing environment. Our bordered hydrocolloid dressings offer high absorbency and are comfortable to use..
EASY TO APPLY AND REMOVE: Soft and hypoallergenic adhesive acts as a wound contact layer that does not stick to the wound bed but to intact skin thus prevents secondary damage and minimizes pain during dressing removal and change..
SEMI-PERMEABLE: Semi–permeable PU film acts a liquid barrier while allows the passage of oxygen and water vapor. The multilayer structure works together to create a high absorbent yet breathable surface keeping the wound moist and sterile..
STERILE AND INDIVIDUALLY WRAPPED: Each dressing is manufactured in a sterile facility and are individually wrapped to prevent contamination of wounds. Can be used in hospitals, senior care homes, hospice, and other medical facilities..
MULTI-USE: Effective for applications such as post-operative wounds, bed sores, cysts, pressure ulcers, burns, and other minor traumas. Approved for Level II of the Healthcare Common Procedure Coding System (HCPCS). Use code A6234 for billing/claims..
