The core functionality of the DS18B20 is its direct-to-digital temperature sensor. As with the measurement of weight and temperature, the selection of the humidity sensor must first determine the measurement range. And really easy to use! All devices combine fully factory-calibrated humidity and temperature sensor elements with an analog-to-digital converter, signal processing, and an I 2 C host interface. They provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature. They’re analog sensors, so the code is relatively simple compared to digital temperature sensors that require special libraries and lots of code. Texas Instruments LM57 Temperature Switch/Analog Temperature Sensors are a precision, dual-output, temperature switch with integrated analog temperature sensor.
