The **HTS-01-R/BN** is a high-precision, industrial-grade humidity and temperature sensor probe, typically utilized in environmental monitoring systems and climate control applications. --- ### 1. General Specifications This sensor is designed for durability and accuracy. Below are the primary electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Model** | HTS-01-R/BN | | **Sensor Type** | Digital Capacitive (Humidity) / NTC or RTD (Temperature) | | **Connection Type** | Circular Connector (BN series often denotes specific pin configurations) | | **Interface** | Usually I2C or RS485 (depending on the internal transmitter) | | **Housing Material** | Stainless Steel or High-grade Polymer | | **Protection Rating** | IP65 or higher (Dust and Water-resistant) | --- ### 2. Core Electronic Components The device is comprised of several critical electronic stages: * **Sensing Element:** * **Humidity:** Uses a polymer capacitive sensor that changes capacitance based on the dielectric constant of the air. * **Temperature:** Employs a high-precision thermistor (NTC) or a Platinum Resistance Thermometer (PT100/PT1000). * **Signal Conditioning (ASIC):** * Includes an internal Analog-to-Digital Converter (ADC). * Applies factory-calibrated coefficients to ensure linear output. * **Protection Circuitry:** * Integrated TVS (Transient Voltage Suppressors) to protect against electrostatic discharge (ESD) and voltage spikes. * Reverse polarity protection to prevent damage during installation. --- ### 3. Pinout and Wiring (Typical) While specific colors can vary by manufacturer, the BN-type connector usually follows this 4-wire standard: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | VCC | Power Supply (typically 3.3V - 5V or 12V-24V for RS485 versions) | | 2 | GND | Ground | | 3 | DATA / A | Digital Data line or RS485 A (+) | | 4 | CLK / B | Clock line or RS485 B (-) | --- ### 4. Key Application Areas * **HVAC Systems:** Monitoring building automation and air quality. * **Data Centers:** Ensuring server racks stay within thermal and moisture limits. * **Greenhouses:** Controlling irrigation and ventilation based on vapor pressure deficit (VPD). * **Cold Chain:** Monitoring perishable goods during transport or storage.
