MD-HT wireless temperature and humidity meter Introduction
The MD-HT series of intelligent temperature and humidity products include a variety of products for different scenes. It can be equipped with a split probe or an integrated probe. The product is equipped with a mounting bracket for wall mounting.
This series of products includes 4-20mA current (HT-A), RS485 (HT-R) two wireless output solutions, equipped with LCD liquid crystal display, showing the current temperature and humidity values while data is transmitted remotely.
At the same time, the series of temperature and humidity products also include intelligent terminals of GPRS/LoRA/NB-iot wireless output, and the output protocol supports UDP/TCP/MQTT/CoAP protocol.
The product has high precision, good stability and long service life. The design and application scenarios are the occasions where the temperature and humidity need to be monitored in the pump room, machine room, factory building, exhibition hall and other exhibition halls.
