The temperature and humidity digital sensor is a new high-tech product developed by our company, which is designed by advanced embedded 10M TCP/IP network module, high-precision digital temperature and humidity sensor, embedded microcontroller and so on. With high reliability and excellent long-term stability, equipped with a large screen LCD display, can real-time display sensor reflected temperature, humidity; At the same time, the actual alarm state can be indicated by indicating the arrow.
Function description: TCP/IP bus interface, to ensure the convenience and security of equipment communication; Large-screen LCD display, LED backlight, real-time reflect the temperature, humidity value and alarm state (up and down arrows);
The sensor is separated from the control part to achieve better ventilation contact with the outside world, which can greatly improve the accuracy of the measurement of temperature and humidity; The upper and lower limits of temperature and humidity are set freely, and the real-time relay output exceeds the set value;
Strong anti-interference ability, ultra-low power consumption, three-level lightning protection; Meet the explosion-proof requirements;
Accurate and stable measurement, high precision, high cost performance and other advantages.Applicable place: It is suitable for wireless base station, large warehouse, equipment room, power station and other places with strict temperature and humidity requirements and need real-time monitoring
