TSH330 is an IP54 temperature and humidity sensor with an RS-485 interface. It supports the Modbus RTU protocol. The temperature and humidity sensor integrates basic elements plus signal processing and provides a fully calibrated digital output. A unique capacitive element is used for measuring relative humidity while the temperature is measured by a bandgap element. Both elements are seamlessly coupled to a 12-bit analog to digital converter. This results in superior signal quality. The digital sensor is mounted in an IP65-rated enclosure. This provides protection against dust and water sprays. A cable gland with locknut and screwless terminal block allows easy cable installation.

Features:
• RS-485 interface carrying up to 32 nods
• LED indicator for status of communication
• Changeable bitrate and other communication parameters
• Firmware update via the interface

Applications:
• Server room and data centers humidity and temperature logging
• Environmental quality monitoring and assessment
• Humidity and temperature monitoring in building management systems
• Humidity and temperature logging for mobile operator facilities, vineyards, greenhouses, etc.

The TSH330 temperature and humidity sensor can be used with:
• Temperature and humidity data logger TCW210-TH
• Energy monitoring module TCW260
• GSM-GPRS remote IO module TCG140
• 4G LTE universal IO module TCG140-4

Specifications
Dimensions	65.6 x 99 x 36 mm
Operating temperature range	-20 to 60°C
Operating relative humidity range	5 to 95% (non-condensing) 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.
