I am using an ESP32 with a Max30102 sensor to get HR readings. I also use ESP-IDF and the <driver/i2c.h> library to access the needed memory registers. From my understanding of the Max30102 sensor documentation, I have two registers, FIFO_RD_PTR and FIFO_DATA, that give me access ...

无线传感器网络(WSNs Wireless Sensor Networks)的一个重要讨论和研究课题一直是传感器节点的能量消耗。很明显,越少越好。如果你有一些开发电池操作的无线设备的经验,你知道运行到睡眠的概念,这意味着做完工作后尽快进入睡眠模式,以保存最宝贵的资源--能源。尽管如此,无论你做什么,传感器节点必须消耗能量,用户在一段时间...

2. Does anyone know if there is a PIR Sensor that has a bigger range than 3-7 meters (for example 10-15m) 3. Is it possible to have a single cam for Daytime and Nightime pictures utilizing a IR Cut Filter Switcher? Any feedback / advice / comments are highly appreciated. Thanks...
