The Sonoff THS01, RJ11 Temperature and Humidity Sensor is a simple yet extremely useful smart sensor that allows you to monitor key environmental data in your living or working spaces. Its main advantage is that it provides comfort and better climate control, making it perfect for people who value smart, practical solutions for a comfortable home.

This sensor is designed for anyone who wants to monitor the temperature and humidity in a room or other location (e.g. greenhouse, basement or office) in real time. It enables improved control of heating, air conditioning and humidifiers - especially useful for smart homes, where the desire is for maximum comfort and optimized energy consumption.

Key technical features include accurate temperature and humidity detection and wired connection via RJ11. The sensor is designed to be easily connected to selected Sonoff smart devices (such as Sonoff TH or THR), allowing for instant data reading and automation of smart scenarios – for example, automatically turning on the heating or turning off the humidifier when needed.

Using the sensor is completely simple - plug it into the appropriate Sonoff device, it automatically detects changes and transmits data to the application. It particularly stands out for its excellent responsiveness and easy integration into a smart home, as it does not require an additional Wi-Fi or ZigBee connection to operate, but connects directly via cable. This allows for reliable measurements without interference or complicated setup, which is a great advantage in everyday use.

The modern design and the ability to accurately measure temperature (-40°C to 80°C) and humidity (0%–100% RH) ensure flexibility and usability in both residential and technical spaces. It gives the user a sense of security, control, and facilitates automation and energy efficiency - all with just one compact sensor.

Same summary

The Sonoff THS01 temperature and humidity sensor allows you to monitor basic environmental parameters in indoor spaces, but requires a connection to a central unit to operate. It is especially suitable for those who already use or plan to use a central smart home system, as independent operation without an external unit is not possible. It is also worth considering that the device does not support WiFi connection, so it is a good idea to check whether it fits the existing equipment and methods of use in your home. The advantage of this sensor is primarily its easy integration into the wider Sonoff ecosystem.
