DS18B20 Digital Temperature Sensor

The DS18B20 Digital Temperature Sensor is a compact electronic probe used to measure temperature and send readings to a microcontroller as a clean digital signal. It is a favourite choice for makers, students, and growers building smart irrigation timers, hydroponic monitors, greenhouse controllers, and DIY garden automation around boards like Arduino, ESP32, and Raspberry Pi.

Key features

• Digital output for stable, noise-resistant readings over longer wiring runs.
• Each sensor carries a unique address, so several units can share a single data line.
• Small probe form factor that fits easily into soil setups, water tanks, and enclosures.
• Works smoothly with popular maker boards and widely available code libraries.

Typical uses

• Monitoring water or nutrient-solution temperature in hydroponic and drip systems.
• Greenhouse and grow-room climate monitoring.
• Smart irrigation and automation projects that react to temperature changes.
• Educational electronics and prototyping projects.

How to choose / tips

Pick the probe style that suits your setup: a bare sensor for breadboards and enclosures, or a sealed probe version where moisture is present. Confirm your board's voltage and use the recommended pull-up resistor for reliable digital communication.
