Barometric pressure sensor 05419980214201-1

RS-485ModbusUART

• Stainless steel enclosure and filter cap, engineered to shield sensing elements in harsh environments • Waterproof protection of internal electronics—only sensor elements are exposed • UV-protected and oil-resistant flexible cable • Low-power consumption suitable for battery-powered applications • Electrical interfaces: SDI-12 (SDI-12 protocol v.1.4), RS-485 (Modbus protocol), UART (Modbus protocol), NMEA-0183 over RS422, USB The Evvos RHTP probe combines meteorological grade sensors for air temperature, relative humidity, and barometric pressure measurements. It is designed to provide high-quality environmental data, real-time measurements, and calculation of multiple derivative parameters. The RHTPCO2 version of the probe includes an additional measurement of CO2-percentage (in air) compensated for relative humidity and air temperature. It is compatible with OneSense Pulse and Voltage and OneSense Environment and Agriculture as well as many other telemetry transmitters or dataloggers supporting SDI-12, Modbus/RS-485, or NMEA 0183 interface.
