Description
Overview
GAOTek Wi-Fi temperature and humidity sensor with LCD display is an industrial temperature and humidity data logger for WIFI wireless data transmission. It can upload up to 4 channels of temperature and humidity data to the server through WIFI. The data logger adopts imported high-precision sensors, and the default line length is 8 meters. This series of products make full use of the already established WIFI communication network to achieve data acquisition and transmission and achieve the purpose of centralized monitoring of temperature and humidity data. It can greatly reduce the construction amount and improve construction efficiency and maintenance cost.
