This docum ent contains proprietary technical inform ation which is the property of NETVOX Technology. It shall be m aintained in strict confidence and shall not be disclosed to other parties, in whole or in part, without written perm ission of NETVOX Technology. The specifications are subject to change without prior notice. R718 A Temper atur e and Humi di t y Sensor for Low Temper atur e Envi r onment Gener al Descr i pti on NETVOX Wireless Sensor R718A is capable to measure temperature and humidity at low temperature environment. R718A can be used in domestic and commercial refrigerators to store and transport food, medicines, flowers and other perishable goods, on the walls or in logistics refrigerators. Suitable as a data logger. Pr i nci pl e of Oper ati on R718A carries a built-in SHT-35 temperature and humidity sensor. SHT-35 temperature and humidity sensor can detect the current environment temperature and humidity. SHT35 temperature and humidity sensor and module (R100H/R100L) communicate through I2C.
