| Product Introduction
The WCTH300 series 4G wireless display-head temperature and humidity sensor, is an industrial-grade remote monitoring terminal integrating temperature and humidity acquisition, LCD display head and 4G wireless transmission. With a high-accuracy temperature and humidity probe, the on-site LCD display head shows temperature and humidity data in real time, and via 4G full network with MQTT / HTTP protocols it uploads data to a cloud platform or customer server with no wiring, suitable for distributed points and unattended scenarios. The WCTH300 series 4G wireless display-head temperature and humidity sensor is powered by a low-power battery and can address temperature and humidity measurement in cold chain warehousing, agricultural greenhouses, server rooms, laboratories, pharmaceutical GSP and industrial workshops.
