DS18B20 Waterproof Temperature Probe
—The DS18B20 waterproof probe is a stainless-steel-sheathed digital temperature sensor on a lead, readable over a single-wire bus that supports many sensors on one pin.
Specifications
- Range -55 to 125°C, accuracy ±0.5°C from -10 to 85°C
- 1-Wire bus — dozens of probes share one GPIO
- Each sensor carries a unique 64-bit address
- Stainless steel probe on a 1m lead
- 3.0-5.5V supply
- 9 to 12-bit selectable resolution
What you can build with the DS18B20 Waterproof Temperature Probe
- Hot water cylinder and pipe temperature
- Aquarium, pond and pool monitoring
- Soil temperature at several depths
- Fridge and freezer alarms
- Multi-point heating system logging
Compatibility
Works with Arduino, ESP32, ESP8266 and Raspberry Pi using the OneWire and DallasTemperature libraries. Needs a 4.7kΩ pull-up resistor on the data line if the module does not already have one fitted.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
