OPERATION AND INSTALLATION MANUAL
Temperature and humidity measuring sensor - TEMPHU
V2.5 Published on 2021-08-16
The main technical characteristics and benefits of TEMPHU sensor:
•Compatible with LoRaWAN® specification 1.0.3
•Measures temperature
•Measures humidity
•Measurements at regular intervals with integrated advanced intelligent (AI) computational algorithms
•Indoor use
•Easy to use and deploy
•Powered by batteries
•Data transmission up to 10 km.
•Battery life is up to 10 years depending on settings and environmental conditions
General information
The TEMPHU is advanced technology sensor measures the magnitude of the
temperature, humidity and used indoors. The data transmitted from the sensor is based
on Class A LoRaWAN® wireless network. TEMPHU is powered with one or two batteries
and able to operate up to 15 years depending on the configuration and either one or two
batteries are inserted. The TEMPHU sensor is easily configured and connected to the
LoRaWAN® wireless network. The calibration is not needed for the TEMPHU since it has
automatic self-calibration based on integrated advanced intelligent (AI) computational
algorithm.
Applications
•Indoor environment measuring
•Smart buildings
•Government buildings
•Public buildings
•Banks
•Industrial facilities
•Factories
Product features
•LoRaWAN communication
•Computational AI algorithm.
•Indoor temperature sensor
•Indoor humidity sensor
•Configuration over the air
•Robust enclosure
•Auto self-calibration

Push button and LED indicator description:
•Once battery (batteries) is installed or reset button will be pushed in the sensor, it will
automatically attempt to connect to the LoRaWAN network and the LED indicator will start to be
blinking / flashing for 5 blinks.
•In case of the successful connection to the LoRaWAN network LED indicator will stay on for 3
seconds and LED indicator will stop flashing and go dark. This means sensor successfully connected
to the LoRaWAN network.
•If the sensor will not connect on the initial try, it will attempt to connect to the LoRaWAN network
after 10 seconds, then after 60 seconds, then after 10 minutes, then after 1 hour, then after 24
hours till successful connection to the LoRaWAN network.
•The sensor will restart by pressing the button on the sensor and it will attempt instantly to connect
the LoRaWAN network.
The TEMPHU sensor has tobe installed reliably and with appropriate screws. The sensor must not be placed
near any air vents windows, door openings where the constant fresh air flow is possible. The sensor is not suitable
to be installed for the outdoor locations. The sensor cannot be stored at dusty or dirty areas with excess operation
and storage temperature. The sensor is not washable, paintable. The open holes of the case must not be blocked,
glued with any material. Do not throw the battery into a fire to prevent the battery from exploding. Damaged
batteries may also explode. All of the above suggestions apply equally to your device, battery and accessories.
The TEMPHU sensor is maintenance free except replacement of the batteries.

Important safety information
Read this manual before attempting to install the device. UAB „ Nano sensorics” will not accept
responsibility for any damage or injury resulting from not following the instructions in this manual.
•The sensor is for indoor use;
•Do not disassemble, crush, puncture, short internal circuits;
•Remove batteries if the sensor is not used, discharged battery has to be removed from the battery sensor,
in this case left batteries might leak and damage the sensor.
•Keep the battery or device dry and away from water or any liquid as it may cause a short circuit.
•Replace batteries only with the same or equivalent type recommended by the manufacturer
•Discard used batteries according to the manufacturer’s instructions
•Do not bend, deform, shred, microwave, paint the sensors, or other hardware.
•Do not insert external material into any opening on the sensors
•Disassembling or puncturing the battery (whether integrated or removable) can cause an explosion or fire.
•Do not dry the sensors or battery with an external heat source such as a microwave oven or hairdryer
•Observe proper precautions when handling batteries. Batteries may leak or explode if improperly handled.
