Tips: "4-20mA/RS485/0-10V output" in Temperature and Humidity Sensor

Temperature and humidity sensors with 4-20mA, RS485, or 0-10V output are designed for easy integration with various industrial control systems.

• 4-20mA Output: A standard analog signal widely used for long-distance transmission with strong anti-interference capability. Common in industrial automation.
• RS485 Output: A digital communication interface, often using Modbus protocol, suitable for multi-point data transmission and precise monitoring.
• 0-10V Output: Another analog signal option, typically used for short-distance transmission in building automation or HVAC systems.
• These output options allow the temp and humidity sensor to be connected to PLCs, data loggers, or monitoring systems for real-time data collection and control.
