System Framework Diagrams
NOTE: When the system needs to access an analogue version of the sensor, you only need to supply power to the temperature and humidity sensor, and at the same time, connect the analogue output line to the DI interface of the microcontroller or PLC, and at the same time, according to the conversion relationship in the following section, you can write the corresponding acquisition program.
Application
Tips: How accurate is this temperature and humidity sensor?
ATO stainless steel duct temperature and humidity sensor uses a high-precision sensing element and is able to provide a measurement accuracy of ±0.5°C for temperature and ±3% for humidity. This allows it to excel in industrial, agricultural, and environmental monitoring applications where high reliability is required. In addition, the temperature humidity sensors undergo strict calibration and quality testing to ensure the reliability and consistency of the measurement results, providing customers with accurate environmental monitoring.
