| Product Introduction
The WCTH200 series IIC-output temperature and humidity sensor probe developed and produced by winchen sensor is a digital temperature and humidity probe for embedded acquisition, industrial environmental monitoring and IoT terminals. The probe has a built-in high-accuracy temperature and humidity sensing unit and communicates with the host MCU, PLC and data acquisition module via the IIC (I2C) bus, directly outputting calibrated digital temperature and humidity signals, addressing the monitoring and control needs of chemical, environmental protection, scientific research, pharmaceutical, warehousing, agricultural, urban building system and other fields.
| Features
1. IIC digital output: standard bus communication, directly reads temperature and humidity data, easy to interface with MCUs, PLCs and acquisition modules.
2. High-accuracy calibration: factory calibrated, good temperature and humidity consistency, small long-term drift, suitable for precision environmental monitoring.
3. Low-power design: suitable for battery-powered, low-power acquisition and IoT terminal applications.
4. Strong anti-interference capability: digital signal transmission, suitable for wiring over a certain distance, shielded cable optional.
5. Wide voltage compatibility: supports 3.3V~5V wide-voltage supply.
6. Stable and reliable: optional industrial-grade protection, adaptable to complex temperature and humidity environments.
