The 7Semi Industrial RS485 Temperature & Humidity Sensor Probe is an industrial-grade sensor engineered for precision and durability in demanding environments. Leveraging Modbus RTU over RS485, it delivers highly accurate readings with excellent long-term stability. Housed in a robust stainless steel probe with a breathable and dust-resistant sintered metal filter, it’s ideal for HVAC systems, building automation, climatology, and industrial monitoring.
This version includes a 2-meter, features a wide 9–36V DC input range, DIP switch-configurable Modbus address and baud rate, and onboard signal processing. Fully plug-and-play with SCADA, PLCs, HMIs, and Arduino/MCUs.
