Waterproof DS18B20 Temperature Sensor Probe – Digital 1-Wire Thermal Sensor for Arduino & ESP32 in Pakistan

Overview 

The DS18B20 Waterproof Temperature Sensor provides 9 to 12-bit Celsius temperature measurements. Unlike analog sensors (like the LM35), the DS18B20 is digital, meaning the signal doesn’t degrade over long cable lengths. Its most famous feature is the 1-Wire interface, which allows you to connect multiple DS18B20 sensors to a single digital pin on your Arduino or ESP32. Each sensor has a unique 64-bit ID burned in at the factory to make identification easy

Key Features 

• Fully Submersible: The 6mm x 50mm stainless steel probe is anti-rust and waterproof, ideal for water tanks and harsh environments.

• 1-Wire Interface: Requires only one port pin for communication, saving your GPIO pins for other components.

• No External Components: Everything is built into the probe (though a pull-up resistor is needed for the data line).

• Wide Range: Accurate readings from -55°C to +125°C.

• Flexible Power: Can be powered through the data line (“parasite power mode”) or a dedicated power wire.
