The INFWIN DigiTHP-GEN2 is an air humidity, temperature, and barometric pressure sensor with a digital SDI-12 or RS485/Modbus-RTU interface. Its sensing elements sit on a PCB in the sensor tip, with the acquisition circuit fully over-moulded and each unit individually factory-calibrated. At just 110 × 16 mm, it fits into most standard radiation shields and field enclosures. Accuracy grade, power supply, output interface, encapsulation, connector, and cable length are all configurable via ordering code - the default variant (DigiTHP-GEN2-AACAAB002) ships with RS485/Modbus-RTU output, SHT40/BMP280-grade accuracy, 4.5–18V DC supply, standard encapsulation, a cold-pressed terminal connector, and a 2 m cable.

Temperature and humidity are measured with a precision SENSIRION sensor, with barometric pressure measured by an additional BOSCH MEMS chip. From these, DigiTHP-GEN2 derives secondary values including dew point, frost point, vapor pressure, and vapor concentration. Reverse power protection and built-in TVS/ESD protection are included.

Key Features

  • Triple measurement: Air humidity, temperature, and barometric pressure in a single sensor
  • Secondary calculated values: Dew point, frost point, vapor pressure, and vapor concentration
  • Precision sensing elements: SENSIRION humidity/temperature sensor plus a BOSCH MEMS barometric sensor; each unit individually factory-calibrated
  • Selectable accuracy grade: SHT40 & BMP280 (±0.2°C, ±1.8% RH, ±1 hPa typical) or SHT45 & BMP280 (±0.1°C, ±1.0% RH, ±1 hPa typical)
  • Digital output: SDI-12 (V1.3) for universal datalogger compatibility and low-power use, or RS485/Modbus-RTU for long cable runs or multi-sensor networks
  • Compact size: 110 × 16 mm sensor body fits standard radiation shields
  • Cleanable filter cap: 10 µm copper sintering filter protects the sensing elements and can be cleaned in place
  • Flexible mounting: Wall mounting or pipe flange insertion
  • Reverse power protection: Built-in TVS/ESD protection
  • RS485 Modbus-RTU protocol: Standard Modbus register map; configurable slave address, baud rate, parity, and stop bits
  • Connector options: Cold-pressed terminal or stripped & tinned lead wires
  • Configuration utility: SensorOneSet software included for sensor configuration via RS485
  • Cable length: 2 m standard; custom lengths available

Applications

  • Smart agriculture and greenhouse monitoring
  • Canopy monitoring
  • Reference evapotranspiration calculations
  • Routine weather monitoring
  • Building humidity monitoring and mold remediation
  • Modeling processes affected by vapor pressure or humidity
  • LoRaWAN IoT deployments via the Catena-5310 or compatible RS485/Modbus-RTU/SDI-12 gateway

Important Notes

  • The long-term operating temperature is −40°C to +80°C, even though the temperature sensing element itself is rated to +125°C.
  • IP56 rated - protected against dust ingress and water jets, but not rated for submersion or direct burial.
  • Operating environment is non-condensing.
  • The copper sintering filter cap can be cleaned in place; replace if damaged to maintain accuracy and IP rating.
