DS18B20 Temperature Sensor for Medical Ventilator

DS18B20 Temperature Sensor for Medical Ventilator

The DS18B20 does not require an external power source to function. The device is powered when the data line DQ is high. The internal capacitor (Spp) charges when the bus is pulled high, and the capacitor powers the device when the bus is pulled low. "Parasitic power" is the term used to describe this method of 1-Wire bus device powering.
