Waterproof Temperature and Humidity Sensor TSH230

Temperature and Humidity Monitoring

TSH230 is a waterproof 1-Wire temperature and humidity sensor. It uses a unique capacitive element for humidity and a bandgap element for temperature, coupled with a 12-bit analog-to-digital converter for precise measurements. Ideal for IP54-protected applications, TSH230 can be used with Teracom Ethernet or cellular controllers. It communicates over a 1-Wire bus, with each sensor having a unique 64-bit serial code for multi-sensor support. Housed in an IP65-rated enclosure, it offers protection against dust and water, featuring a cable gland for easy installation.

Features of the TSH230 Sensor:

  • 3.0% relative humidity accuracy
  • 12-bit humidity measurement resolution
  • 14-bit temperature measurement resolution
  • Outstanding long-term stability
  • Firmware updates through the interface
  • Unique 64-bit serial numbers for multi-sensor support

Applications of the TSH230 Sensor:

  • Fleet management systems
  • Environmental quality monitoring and assessment
  • Humidity and temperature monitoring in vineyards, greenhouses, etc.
  • Humidity and temperature logging for telco facilities
  • Humidity and temperature monitoring in server rooms and data centers
  • Humidity and temperature monitoring in building management systems (BMS)

    * Recommended operating range is 20% to 80% RH (non-condensing) over –10 °C to 60 °C.
    Prolonged operation beyond these ranges may result in a shift of sensor reading, with slow recovery time.
    It is possible that in some weather conditions the moisture in the air in the filter cap may condense. This may result in a
    shift of sensor reading, with slow recovery time.
    ** Higher drift values might occur due to contaminant environments with vaporized solvents, out-gassing tapes,
    adhesives, packaging materials, etc.
