Product information

Description

Sonoff DS18B20 TH wired temperature sensor is a compact probe designed to measure ambient temperature for indoor and outdoor applications. The sensor uses the DS18B20 probe element and connects via a wired interface to Sonoff controllers and compatible monitoring systems. It provides a straightforward way to add temperature sensing to HVAC systems, climate monitoring, greenhouses, aquariums and smart home automation setups.

Advantages

The sensor offers reliable temperature measurement with a durable wired connection that minimizes signal interference and ensures stable data transmission. Its probe construction is suitable for a variety of mounting locations and environmental conditions, allowing continuous monitoring. Integration with Sonoff devices and common automation platforms enables automated actions based on temperature thresholds and simple data logging for system diagnostics.

Suitable for

Home and building HVAC monitoring and control
Greenhouse and plant environment monitoring
Aquarium and terrarium temperature tracking
Server rooms and equipment cabinets temperature surveillance
Smart home automation scenes and conditional rules

Key specifications

Sensor type: DS18B20 digital temperature probe
Connection: wired interface for direct connection to compatible controllers
Measurement range: designed for ambient temperature measurement (refer to manufacturer's DS18B20 probe range)
Probe form factor: compact sealed probe suitable for indoor and sheltered outdoor use
Typical applications: HVAC, environmental monitoring, aquariums, greenhouses, smart home systems

How to use

Connect the wired probe to a compatible Sonoff controller or monitoring device following the controller's wiring diagram and power requirements. After connection, configure the controller or software to recognize the DS18B20 sensor type and set desired reporting intervals. Position the probe in the location where representative ambient temperature readings are needed, avoiding direct sunlight or heat sources for accurate measurement. Verify readings in the controller interface and use calibration features if available to align measurements with a reference thermometer.

Usage recommendations

For reliable long-term operation, route the cable to avoid mechanical strain and protect the probe from prolonged direct exposure to water or extreme weather unless the installation location and probe sealing are suitable. Use short reporting intervals for applications requiring timely alerts and longer intervals to conserve network and controller resources when continuous monitoring is not critical.
