IR Remotes Revisited - 2023 It's time we took a fresh look at infrared remote controls, so here is everything you need to know about using IR remote controls with microcontrollers. Learn how to receive, decode and send IR signals, including ones from those hard-to-decode remotes like air...
它包含两个红外(IR)和一个红色(Red)LED光源以及光敏探测器,通过检测血液对光的吸收变化来计算心率和血氧饱和度。\n\n驱动MAX30102的关键步骤包括:\n\n1. 初始化I2C通信:ESP32S3通过其内置的I2C接口与MAX30102进行通信。需要配置I2C总线的时钟频率、SDA和SCL引脚,并确保正确设置设备地址(MAX30102的默认地址是0x57...
即使在最好的情况下(Ir=10 欧姆),这也意味着内阻会消耗可用 3V 电压中的(U=I*R,0.3A*10ohm=)3V。 换句话说,当 ESP32 启动时,它会从不良的 CR2032 中拉出大量电流,导致电压完全降至零,从而ESP32 复位/崩溃。 可以看到就是到了300mA以上的电流,应该就是峰值了 ...
