Temperature sensor SHELL DS18B20 Wired (1 m cable) – DS18B20 1M

The SHELL DS18B20 Wired temperature sensor with a 1 m cable is a compact, single-wire digital thermometer based on the DS18B20 chip. It provides direct temperature readings through a wired connection and is designed for integration with home automation controllers, monitoring systems and HVAC equipment where precise wired temperature measurement is needed. The sensor's sealed probe and straightforward cable make it convenient to mount in small enclosures, ducts or near components that require continuous temperature monitoring.

Advantages

The sensor offers stable, digital temperature readings with good resolution and accuracy typical of DS18B20-based devices, delivered over a simple single-wire interface. Its 1 m cable provides flexibility for mounting while keeping the electronics outside the measured environment. The compact probe and sealed construction allow use in a range of indoor applications and make installation quick and minimally invasive.

Suitable for

• Home automation systems and smart relays that read external temperature probes
• HVAC monitoring and basic climate control feedback loops
• Environmental monitoring in cabinets, enclosures or small ducts
• DIY electronics projects and single-sensor data logging

When it may not be suitable

This wired DS18B20 sensor is intended for general-purpose temperature sensing; it is not designed for direct immersion in fluids unless explicitly specified by the enclosure rating. It also lacks wireless connectivity and on-board power beyond the standard DS18B20 interface, so it requires compatible host hardware that supports the sensor's protocol and can supply the necessary pull-up or power connections.

Key specifications

• Sensor type: DS18B20 digital temperature sensor
• Cable length: 1 meter
• Probe form factor: sealed compact probe suitable for surface and near-air measurements
• Interface: single-wire digital communication (compatible with DS18B20 protocol)
• Typical use: ambient and surface temperature measurement in electronics, HVAC and home automation

How to use

Connect the sensor's wires to a compatible controller or input that supports DS18B20 devices, observing the correct wiring for data, ground and optional power (parasite or powered mode depending on the host). Configure the host to poll or read the sensor using the DS18B20 protocol and verify readings in the host interface. Mount the probe where it will make reliable contact with the monitored area while avoiding direct exposure to liquids or conditions beyond the sensor's intended environment.

What to consider before purchase

• Confirm your controller or system supports the DS18B20 single-wire protocol
• Verify that a 1 m cable length is sufficient for your installation layout
• Consider whether the sealed probe form is appropriate for the specific environment (e.g., not suitable for prolonged immersion unless specified)

Usage recommendations

For reliable readings, route the cable away from high-voltage or high-interference lines, secure the probe in stable contact with the measurement surface, and configure regular polling intervals in your controller to match the responsiveness required by your application.
