Dallas DS18B20 Original digital waterproof temperature sensor SP13, 3m

Product detailed description

A popular and reliable digital temperature sensor with an original Maxim Integrated DS18B20 chip in a waterproof design, this time featuring a practical SP13 connector for fast and durable solderless connection. The sensor is calibrated with an accuracy of 0.2 °C and, thanks to the waterproof stainless steel probe, can be immersed directly into liquid. The digital output returns the temperature as a direct value, so no conversion is necessary. The 1-Wire bus allows up to 50 sensors to be connected in series on a single cable – each sensor has its own unique address. Works in both normal and parasitic modes. Ideal for smart thermostats, aquarium temperature monitoring, weather stations, or any IoT project in more demanding conditions.

Package contents:

• 1× Dallas DS18B20 Original Digital Waterproof Temperature Sensor - SP13 Connector, 3m

Note:

• Connect a 4.7 kΩ pull-up resistor from the DQ data line to the supply voltage; otherwise, 1-Wire communication will not function.
• The stainless steel probe and cable are waterproof – do not attempt to immerse the SP13 connector itself in liquid.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
