## Summary description

Inline temperature sensor No name CT-DS18B20-M4/3M is a DS18B20-based digital temperature probe with a 3 m cable. Designed for direct temperature measurement and monitoring in HVAC, aquariums, refrigeration and embedded systems. Provides a single-wire digital interface (DS18B20) for easy integration with microcontrollers and controllers for automated temperature reading.

## Long description

Inline temperature sensor No name CT-DS18B20-M4/3M is a waterproof digital probe based on the DS18B20 integrated circuit with a 3 m cable. The sensor provides accurate single-point temperature measurement and a one-wire digital interface for easy integration with microcontrollers, PLCs and HVAC controllers. Its compact metal probe and long cable make it suitable for direct immersion or surface contact measurement in refrigeration, aquariums, heating systems and embedded electronics projects.
Advantages
The DS18B20-based probe delivers digital temperature data with built-in calibration, eliminating the need for external analog signal conditioning. The 3 m PVC-insulated cable increases installation flexibility and allows placement away from the controller. The metal-sheathed probe offers durable physical protection and improved thermal contact for faster response. The one-wire interface supports multiple sensors on the same bus, simplifying wiring in multi-point monitoring setups.
Suitable for
HVAC temperature monitoring and control
Aquarium and terrarium temperature measurement
Refrigeration and cold chain monitoring
Embedded systems and microcontroller projects
Environmental data logging and laboratory setups
Key specifications
Sensing element: DS18B20 digital temperature sensor
Measurement range: DS18B20 standard operating range (sensor-specific)
Accuracy: DS18B20 typical accuracy specifications (sensor-dependent)
Interface: One-wire digital bus (single-wire, compatible with DS18B20 protocol)
Cable length: 3 meters, PVC insulated
Probe material: Metal-sheathed inline probe for direct contact or immersion
Mounting: Inline probe suitable for insertion or surface contact
How to use
Connect the sensor to a compatible controller or microcontroller using the one-wire interface: VDD, GND and data line (with optional pull-up resistor as recommended for DS18B20). Place the metal probe in the measurement location — either immersed where waterproofing is required or fixed to a surface for contact measurement. Configure the host device to detect the DS18B20 sensor address and read temperature values using standard one-wire commands. For multi-sensor setups, place each sensor on the same data bus and address them individually.
Usage recommendations
To ensure reliable readings, route the 3 m cable away from high-voltage lines and strong RF sources. Use a proper pull-up resistor (typically 4.7 kΩ) on the data line when operating in parasite-power mode is not used. For immersion applications verify seal integrity of the probe connection and avoid prolonged exposure to aggressive chemicals. When installing in ducts or tanks, allow time for the probe to reach thermal equilibrium before recording values.
