PRODUCT SPECIFICATION WTH300 Temperature and Humidity Sensor Beacon Product Name Ordering Code WTH300 Temperature and humidity sensor beacon WTH300 Firmware Version Hardware Version V1.1.0 V1.0.0 Configuration App Available (iOS & Android) SDK Kits Cloud Platform Available Available for testing Certification FCC Launched Time October-25-2016 Remarks NULL 1 / 4 1. INTRODUCTION More than waterproof and portable, WTH300 is one type of high precision digital temperature and humidity indicator
(thermo-Hygrometer). It can convert the environmental temperature and humidity into correspondent digital signal. By connecting to wireless network, it can upload temperature and humidity data to the server. Selected high quality integrated digital temperature and humidity sensor module is used for WTH300, which ensures the transmitter s good long-term stability, low latency and ability to resist chemical contamination, thus possessing excellent repeatability. 2.
