Digital temperature sensor DS18B20 probe
Digital temperature sensors are known for its digital output and high precision. With its wide temperature range and low power consumption, it is ideal for applications such as environmental monitoring, industrial automation, medical and HVAC systems.
Typical Applications
- Heating System
- Measuring Instruments
- Washing Machines
- Over-heating Protection
Overview
The DS18B20 digital temperature sensor 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) for communication with a central microprocessor. It has an operating temperature range of -55ºC to +125ºC and is accurate to ±0.5ºC over the range of -10ºC to +85ºC.
