Temperature Sensor -55C to 125C with 1-Wire Interface, 910mm Cable

The Whadda WPSE324 Temperature Sensor is a precision digital thermometer designed for Arduino projects and other electronics applications. Featuring a high-quality stainless steel probe, it delivers reliable temperature readings across a wide range of -55°C to +125°C. The sensor’s unique 1-wire interface simplifies connections, requiring only a single port pin for communication, making it ideal for various DIY and embedded projects.

With multidrop capability, you can connect multiple sensors on the same bus, perfect for distributed temperature sensing applications. The sensor is powered directly from the data line, eliminating the need for an external power source and reducing standby power consumption. It offers high accuracy of ±0.5°C from -10°C to +85°C, with programmable resolution from 9 to 12 bits, allowing you to balance speed and precision according to your needs.

The device includes user-definable, non-volatile temperature alarm settings, and an alarm search command that identifies any sensor outside programmed limits, enhancing your monitoring capabilities. The package comes with a 910mm cable and a 3-wire adaptor for easy Arduino integration, with colour-coded wires (Red: 3-5V, Black: Ground, Yellow: Data). The stainless steel tube measures 30mm in length and 6mm in diameter, ensuring durability and quick thermal response.
