DS18B20 Water Proof Temperature Probe – Black (1m) Original Chip

The DS18B20 Water Proof Temperature Probe operates using a DS18B20 sensor encapsulated in a stainless steel tube, which is waterproof and moisture-proof. It uses a 1-Wire interface for communication, allowing multiple sensors to be connected to a single digital pin on a microcontroller. Each sensor has a unique 64-bit ID for identification. The sensor converts temperature data to a digital signal, which can be read over a long distance without signal degradation.

DS18B20

• Avoid Physical Damage: Do not expose the probe to conditions that could physically damage the stainless steel tube.,
• Prevent Exceeding Temperature Limits: Do not use the sensor beyond its operating temperature range of -55°C to 125°C.

• Use With Microcontroller: Connect the sensor to any microcontroller using a single digital pin.,
• Use Pull-Up Resistor: Attach a 4.7kΩ resistor between the DATA and VCC lines when connecting to a microcontroller.,
• Check Connection Polarity: Ensure the red wire is connected to VCC, the yellow/white wire to DATA, and the black wire to GND.

• Minimum: 9-bit,
• Maximum: 12-bit

• Minimum: -55°C,
• Maximum: 125°C

• Minimum: 3V,
• Maximum: 5.5V

• Single Pin Connection: Multiple DS18B20 sensors can be connected to a single digital pin, each identified by a unique 64-bit ID.

• Red Wire: Connect to VCC (3 to 5.5V),
• Yellow Or White Wire: Connect to DATA (digital input on microcontroller),
• Black Wire: Connect to GND (ground)
