Overview
The Waterproof DS18B20 Digital Temperature Sensor Probe is a temperature probe designed for reliable performance in a variety of environments, including wet or damp conditions. This sensor operates in a temperature range of -55°C to +125°C (-67°F to +257°F) with an accuracy of ±0.5°C in the typical range of -10°C to +85°C, making it ideal for applications such as weather stations, HVAC systems, and liquid temperature monitoring.
The DS18B20 sensor features a digital output via a 1-Wire interface, allowing multiple sensors to share a single data line. It offers a configurable resolution of 9 to 12 bits, providing precise temperature readings. The sensor is enclosed in a stainless steel probe, ensuring durability and complete waterproofing, which makes it suitable for direct immersion in water or other liquids.
It is powered by a voltage range of 3.0V to 5.5V, making it compatible with most microcontrollers and development boards. The probe comes with a 1m, 3m and 5m cable, offering flexibility for installation as pre requirement..
