MD-HT series intelligent temperature and humidity products include a variety of products that are used in different scenarios. They can use split probes or integrated probes. The products are equipped with mounting brackets for easy wall mounting.
The products of this series include 4-20mA current (HT-A) and RS485(HT-R),LCD display, while data transmission, display the current temperature and humidity value.
At the same time, this series of temperature and humidity products also include GPRS / LoRA / NB-iot wireless output intelligent terminal, the output protocol supports UDP / TCP / MQTT / CoAP protocol.
The product has high precision, good stability and long life. The design and application scenarios are pump rooms, machine rooms, factory buildings, exhibition halls and other places where temperature and humidity need to be monitored.
Applications:
Pump room Machine room
Factory building Exhibition hall
Other occasions where temperature and humidity need to be monitored
