Safety information
Read the operating instructions before setup the device.
Connection, mounting, and setting may only be performed by trained persons.
Not a safety component in accordance with the EU Machinery Directive.
When commissioning, protect the device from moisture and contamination.
These operating instructions contain information required during the life cycle of the sensor.
Correct use
zTemp is a precise LoRaWAN temperature sensor device. The sensor element connects to the device
by cable, extendable up to 10 meters.
zTemp LoRaWan is a reliable device, thanks to the digital sensor technology (DS18B20). Not only we
can guarantee accurate results, but the monitoring is easy as well. The temperature sensor element
is located in a sealed stainless-steel tip.

Temperature: -25ºC ~ 50ºC Protection Requirements: IP65
Dimensions: L:64 x W:58 x H:35mm
(Weight: 100g) Accuracy ±0.5°C at -10-85°C
Battery lifetime:
The device can send about 75 000 messages with a 2700mAh Li-SOCl2 battery.
Please note this value is theoretical and it is calculated considering the current consumption of 1
uplink message and sleep current.
Disassembly and disposal
The sensor must be disposed of according to the applicable country-specific regulations. Efforts
should be made during the disposal process to recycle the constituent materials (particularly
precious metals). The sensors contain a lithium battery, which must be disposed of separately.
