SONOFF WTS01 Waterproof Temp Sensor for TH Series

The Sonoff WTS01 Waterproof Temperature Sensor is a reliable tool for monitoring temperatures in wet or outdoor environments. Designed to work with Sonoff TH Elite and TH Origin, it helps you track temperature in areas like greenhouses, water tanks, pipes, aquariums, and more.

Built with a stainless steel waterproof probe and a durable 50cm cable, this sensor can handle water, humidity, and changing weather conditions. It’s ideal for spots where regular sensors fail—such as soil beds, HVAC pipes, or submerged areas.

Setup is simple. Plug the sensor into the RJ9 port of your Sonoff TH device, and it’s ready to go. Use the Smart Life App or eWeLink App to monitor live temperature data. You can also automate connected devices—like turning on a heater when the temperature drops or shutting off a pump when it rises.

This sensor offers fast and accurate readings in both Celsius and Fahrenheit. Its slim build allows easy placement in tight or awkward spaces. Whether you’re working with indoor systems or outdoor projects, it performs reliably.

The WTS01 is low-voltage and safe for continuous use. Its anti-corrosion housing makes it perfect for long-term deployment in moist or wet areas. There’s no risk of short-circuits, and it’s fully insulated for safety.

You can use this sensor to automate smart routines for energy efficiency, plant care, water management, and more. It helps reduce guesswork and prevents issues caused by unnoticed temperature changes.

Whether you’re a DIY smart home user, gardener, or managing a small facility, this sensor adds dependable environmental control to your setup.
