The sensor utilizes the industry-standard Maxim Integrated DS18B20 digital temperature sensor IC, providing calibrated digital output directly over a 1-Wire bus. This eliminates signal conditioning requirements and ensures stable, noise-immune readings. The sensing element is hermetically sealed within a SUS-304 grade stainless steel tube, offering IP68-equivalent protection against water, moisture, and corrosion in demanding environments.
Designed for seamless integration with the Sonoff eWeLink ecosystem for remote monitoring and automation, the probe also functions as a standalone digital temperature sensor for any microcontroller platform supporting the 1-Wire protocol, such as ESP32, STM32, or industrial PLCs with appropriate interface modules.
