Description of DS18B20 Temperature Sensor Probe
Quick Overview
The DS18B20 Temperature Sensor Probe offers highly accurate and reliable temperature measurements in a wide range of environments. With its digital one-wire interface, the sensor is easy to integrate into various systems, making it ideal for applications like climate control, weather monitoring, and thermal management.
How It Works
The DS18B20 uses a digital temperature sensor and a one-wire interface to measure temperature. Inside the probe, a thermistor or semiconductor material changes its electrical resistance based on the ambient temperature. This resistance change is then converted into a digital signal by an onboard ADC (Analog-to-Digital Converter). Basic Functioning involves: Measuring temperature via a thermistor or semiconductor material. Converting the resistance change into a digital signal via an ADC. Transmitting the temperature reading through a one-wire digital interface. The DS18B20 is easily interfaced with microcontrollers like Arduino, Raspberry Pi, or even custom-built hardware, through a single digital pin.
