Sonoff Splash Proof Temperature Probe (Zigbee)

This sensor is designed for precision temperature tracking in environments where traditional sensors may fail. The 1.5-meter stainless steel probe is waterproof and corrosion-resistant, making it suitable for geyser pipes, deep freezers, cold rooms, and aquariums.

The SNZB-02LD connects to Sonoff Zigbee Bridge Pro, NSPanel Pro, or iHost, and is also compatible with SmartThings and Alexa Zigbee. It supports smart scenes, such as turning off a freezer if temperatures rise or sending alerts when thresholds are exceeded.

The LCD display shows real-time temperature data, battery status, and signal strength. The sensor is powered by a CR2477 coin cell battery, offering long-lasting performance with low power consumption.

The sensor body is small enough to mount near geysers, freezers, or tanks, while the long stainless-steel probe allows for flexible placement in enclosed or splash-prone areas. The IP65 rating ensures the probe can handle moisture, though the main unit should remain dry.
