This multi-use 1-Wire®-based sensor can be embedded into walls or fixtures to monitor temperature and humidity. The case has a threaded wall holder that can be screwed into drywall with a few twists, allowing the sensor body to slide in and be almost flush with the wall. A small opening in the front allows the sensor to measure the temperature and humidity; this opening should never be covered or filled. The sensor comes with pre-stripped 18-gauge wires for easy connection using wire nuts.

The SS-Wall-TH uses iButtonLink smart sensor technology to embed a microprocessor into a 1-Wire® sensor, which gives the product more accurate sensing abilities compared to other 1-Wire® humidity sensor designs.

The sensor has a temperature range of -40°C to +85°C, with a typical accuracy of ±0.3°C and a maximum error of ±0.5°C. 

The sensor will work in 0 – 100% relative humidity (non-condensing). While the sensor does have a HDPE cover to protect it from occasional condensation, exposure to frequent condensation is not recommended. The humidity sensor’s accuracy is typically minimum ±2% and max ±3.5% from 0 – 80% RH, with a max error of ±5% above 80% RH.

Like all silicon-based humidity sensors, the SS-WALL-TH does drift over time, and can be adversely affected by continuous exposure to very humid or very dry environments. However, the low maximum drift of 0.5% RH per year allows the sensor to be used for a longer time than other silicon sensors before calibration or testing.

This version of the SS-WALL-TH does not include a case. For a version with a case, please see the SS-WALL-C-TH.

For more information on the SS-WALL-TH Temperature and Humidity Sensor, please visit the SS-WALL-TH user manual or the SS-WALL-TH specification manual.

This product is RoHS compliant.
