Sensors

iButton sensors work in all environments and can be reprogrammed and used for many years. They have low operating costs for any temperature and environment measurements.

The sensors can be found in three versions:

· Digital thermometer (w/o memory)

· Thermochron

· Hygrachron

Digital thermometer

The DS1920 iButton is a digital thermometer that reads the temperature of the environment or of the object to which it is attached. By simply touching the probe it reveals the surrounding temperature, measured within the range of -55°C to +100°C. The data is directly transmitted to the software that is built by us. It is possible to network an unlimited number of sensors and read them simultaneously

Thermochron

The Thermochron sensors can accompany products vulnerable to temperature fluctuations, wherever they go. The tiny, durable sensors monitor the time and temperature, and store the data. The data can easily be uploaded and analyzed to detect possible thermal damage to the product.

Hygrochron

The Hygrochron sensor includes an embedded humidity sensor. Gathering both temperature and humidity data, the Hygrochron logs relative humidity as a function of time. For applications where both temperature and humidity are important (for example, in the case of foods, chemicals, HVAC systems), the Hygrochron delivers unprecedented performance in an unbelievably compact, portable package.
