The term “SHT20 Temperature and Humidity Transmitter” typically refers to a complete sensor unit that incorporates the SHT20 sensor chip along with additional circuitry to make it easier to use in industrial or more robust applications. Instead of just the bare sensor component, a transmitter often includes:
- The SHT20 Sensor: This is the core component responsible for measuring temperature and relative humidity, offering digital I²C output with good accuracy.
- Signal Conditioning: Additional electronics to process the raw signals from the SHT20, potentially including amplification, filtering, and linearization.
- Interface Conversion: Transmitters often convert the SHT20’s I²C output to a more industry-standard communication protocol like RS485 with Modbus RTU. Some might also offer analog outputs (e.g., 4-20mA, 0-10V).
- Power Supply Regulation: A built-in regulator to handle a wider range of input voltages, making it easier to power the device from industrial power sources.
- Robust Housing: Typically enclosed in a protective case or probe, often with features like waterproofing (IP rating), dust resistance, and sometimes a sintered filter to protect the sensor element while allowing air and moisture to pass through.
- Wiring Terminals or Connectors: For easy and secure connection to power and data acquisition systems.
- Mounting Options: Provisions for wall mounting, duct mounting, or probe insertion.
Key Characteristics of an SHT20 Temperature and Humidity Transmitter:
- Sensor: Utilizes the Sensirion SHT20 sensor chip.
- Temperature Range: Typically -40°C to +60°C or +80°C (check specific model).
- Humidity Range: 0% to 80%RH or 0% to 100%RH (check specific model).
- Accuracy: Temperature accuracy typically ±0.3°C to ±0.5°C. Humidity accuracy typically ±3%RH.
- Output Signal: Primarily RS485 with Modbus RTU protocol. May also include analog outputs (4-20mA, 0-10V) in some models. Some might offer standard UART communication as well.
- Operating Voltage: Wider range, often DC 5-30V or similar.
- Power Consumption: Low power consumption, but typically higher than the bare SHT20 sensor due to the added circuitry.
- Communication Address: Can usually be configured (e.g., 1-247 for Modbus).
- Baud Rate: Configurable for serial communication.
- Durability: Designed for industrial or harsh environments with robust housings and protection features.
- Mounting: Various options available depending on the application.
Typical Applications of an SHT20 Temperature and Humidity Transmitter:
- Industrial Monitoring: Factories, warehouses, and production facilities.
- HVAC Systems: Building automation and climate control.
- Environmental Monitoring: Weather stations, greenhouses, and agriculture.
- Pharmaceutical and Food Storage: Ensuring stable environmental conditions.
- Cleanrooms and Laboratories: Precise monitoring of temperature and humidity.
- Equipment Enclosures: Monitoring conditions inside electrical or electronic cabinets.
- Transportation: Monitoring temperature and humidity in vehicles or containers.
- Smart Buildings and Home Automation: More robust and reliable sensing solutions.
In essence, an SHT20 Temperature and Humidity Transmitter takes the accurate sensing capabilities of the SHT20 and integrates them into a more robust, user-friendly, and industry-compatible package suitable for a wider range of demanding applications. It simplifies integration with industrial control systems and provides reliable environmental data.
