Ds18b20 Timing

The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground)... The DS18B20 manufactured by Dallas and Maxim is a very simple to use temperature sensor with a tolerance of ±0.5°C. Its advantages: Very simple to use due to "1-wire" data protocol. Chainable, it is possible to chain up to 100 sensors on one cable (remember ESP Easy has 12 tasks max…). As each DS18B20 has a unique 64-bit serial code burned in at the factory, it's easier to differentiate them from one another. Wiring Multiple DS18B20 Sensors to Arduino. Connections are fairly simple. Start by connecting all the DS18B20s in parallel i.e. common all the VDD pins, GND pins & signal pins.

The DS18B20 Digital Thermometer provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device. Information is sent to/from the DS18B20 over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a DS18B20. Using the DS18B20 one wire digital temperature sensor is easy with some Arduino libraries to provide a simplified interface. Configuring the device and...
