Wireless motion/temperature/humidity sensor tag with internal memory for off-line logging. Requires an Ethernet Tag Manager.

Records temperature and humidity and provides fast too hot/cold/humid/dry notifications independent of recording interval. 

With 8K/16K points of local memory, temperature/humidity recording will keep running during a trip, power or Internet outage of up to a week / 2 weeks (at 1-minute logging interval.) Put inside shipping container, vehicles, or in your backpacks to log temperature & humidity data throughout the trip. Automatically uploads the temperature and humidity data to cloud when back in range, and builds seamless graphs.  

Features:

• Temperature logging and notification with 0.02°C resolution temperature sensor (+/-0.4°C error) from TE France
• Enhanced temperature monitoring while in range (Learn more)
• Air humidity logging and notification with 0.12% resolution +/-1% error RH sensor
• Motion/door open-close logging and notification with angle (3D compass) based motion sensor (except in "no-motion" versions)
• Accelerometer-based version features immediate motion detection, less false alarm rate but does not support horizontal door open-close sensing. Supports garage-door/mail box door and other vertical door open-close sensing. 
• Logging interval programmable from 30 seconds to 4 hours. The "transmit multiple data points at a time" mode improves battery life and allows shorter logging interval.
• Long wireless range allows placing inside most refrigerators/freezer to monitor temperature, humidity & doors (battery life is shorter in cold temperature, recommend use External Power Sensor with larger battery)
• Beep to help find missing items
• Out-of-range/back-in-range notification
• Unlimited storage of logged temperature, humidity and motion event data on cloud (can be deleted any time)
