HTS-1 Precision Sensor for Temperature, Humidity and Barometric Air Pressure

HTS-1 – Temperature and humidity sensor with triple safety

Measuring range: -40°C to 80°C and 0 to 100% relative humidity

Interfaces: RS485, RS232, SD12, USB-C

Reliable climate data – triple-secured

The HTS-1 is more than an ordinary environmental sensor – it is a high-precision, triple-secured measuring instrument For measuring temperature and relative humidity. Three fully integrated sensor elements operate in parallel within a specially designed housing. Their data is processed, compared, and averaged internally to ensure accuracy under real-world environmental conditions. highest accuracy and long-term stability to ensure.

Advantages of the three-sensor architecture

• Redundancy and plausibility checkInternal cross-checking of the sensor elements protects against measurement deviations.
• Averaging for long-term stability: Counteracts the effects of aging and environmental disturbances.
• Measurement reliability under extreme conditionsIdeal for exposed locations or long-term installations.

Physical calibration

Each HTS-1 is individually calibrated – not by mass balancing, but using actual physical reference standards. Temperature and humidity are measured. under precisely regulated comparison conditions Checked at several points to ensure maximum accuracy.

Where others rely on software-based corrections, we use real reference conditions. Other manufacturers skip this effort. We define it as the standard.

Energy efficiency at the highest level

Despite its triple sensor architecture, the HTS-1 extremely energy-efficient – and generates virtually no self-heatingThis eliminates the need for complicated thermal insulation.

• <20 µA in sleep mode
• ~3 mA during active operation
• Automatic power management detects query behavior and dynamically optimizes energy consumption.

Ideal for:

• Solar-powered climate sensors
• Self-sufficient environmental stations
• Battery-powered long-term projects

Full system integration – industry-standard interfaces

The HTS-1 has four digital interfaces, which cover all common industrial protocols. This allows it to be seamlessly integrate into existing systems, whether it's a weather station, environmental monitoring network or mobile research unit.

Available outputs:

1. RS-485
   • Up to 115,200 baud
   • Supported Modbus RTU, Modbus ASCII, ASCII-Stream
   • Ideal for long lines, bus operation, industrial integration

1. RS-232
   • Also up to 115,200 baud
   • Same protocols as RS-485
   • Simple point-to-point communication, for example with data loggers

1. SDI-12
   • Also supports ASCII output
   • Compatible with standard measurement networks

1. USB-C (CDC / Virtual COM-Port)
   • For configuration, live readout
   • Supports data streaming and batch logging on the PC
   • User-friendly, no special interface required.

Other special features:

• ESD protection up to 15 kV on all data lines – ideal for field applications
• Output intervals freely selectable: 1 second to 24 hours
• All settings persist: remain even after power loss
• ASCII streaming modeSensor data is continuously transmitted – perfect for live data acquisition.
