7Semi DS18B20 Digital Waterproof Temperature Sensor Probe 2M Cable

The 7Semi DS18B20 Digital Waterproof Temperature Sensor Probe 2M Cable is a durable, high-accuracy temperature sensor designed for precise digital temperature measurements in wet or outdoor environments. It is based on the DS18B20 sensor, which communicates using the 1-Wire protocol, allowing multiple sensors to be connected to a single data line. The sensor is encapsulated in a stainless steel tube for waterproof protection and includes a 2-meter cable for flexible placement. It is ideal for applications such as weather stations, industrial temperature monitoring, and environmental data logging.
