Presentation


The Temperature and Humidity sensor is a LoRaWAN class A senso that uses a disposable 3.6V AA-type battery as power supply. It also includes an internal antenna.

It measures the temperature, the relative humidity of the remote sensor. It is possible to get the voltage of the power supply. An alert is sent when the case is opened.

Installation and operation


Installation

The housing is intended to be installed inside a building.

First, fix the lid of the sensor to the wall using the screw kit provided. Then attach the case that contains the electronic board to the lid by following the instructions on the label inside the lid:

Radio propagation

In order for the sensor to operate correctly, the number of obstacles should be limited in order to avoid excessive radio wave attenuation. It is also important to place the sensor as high as possible.

Autonomy


The information in the table below represents how long the battery can last. It is based on the default configuration at ambient temperature (+25°C) within the optimal operating range of the sensor via a LoRaWAN network (one uplink frame), when the spreading factor used is SF12.

The disposable battery has a 2.6Ah capacity, of which 85% is used.

Human Machine Interface


There are two LEDs on the device:

Green:      blinking until the association with a network is done.

association

Red:     blinking in configuration mode.

To start up the device, a magnet must be placed next to the sensor for one second (to the left of the cable gland). The red LED blinks quickly during this step. After one second, the red LED stops blinking and the green LED blinks slowly until the association is done.

To switch off the device, repeat the same operation by placing the magnet next to the sensor for 5 seconds. After those 5 seconds, the red LED blinks 5 times slowly.

A reed switch is available under the sticker. A magnet can be used to activate it and perform specific actions on the sensor (switch off, switch on, reassociation…). When the reed switch is activated, the red LED blinks quickly.

Configuration mode
Way to trigger itOne passage of the magnet near the reed switch or specific ZCL command
Way to stop it Another passage of the magnet or specific ZCL command
Effects on the sensorThe CONF led (red) blinks (3 sec. OFF, 3 sec. ON) and the sensor sends an uplink frame every minute.
DurationThe configuration mode lasts 10 minutes
  • A reassociation procedure can be requested if no downlink frame is received by the sensor during a given periodicity (4 days by default) or if a given number (100 by default) is reached or in case of failure (no acknowledgement received) by sending an applicative frame to the sensor or via the sensor’s IHM.

The sensor keeps the AppEUi and DevAddr configured, Confirmed/Unconfirmed configuration and all applicative configurations. However, LoRaWAN configurations (channel, data rate …) are lost.

ReAssociation Mode
Way to trigger itThree passages of the magnet near the reed switch or ZCL command from LoRaWAN cluster.
Effects on the sensorThe ASSN led (green) blinks as the “no commissioned sensor” LED is lit.
  • A factory reset is available on nke Watteco’s sensors. It deletes all the applicative settings saved in the flash memory (i.e. configured batches and reports will be deleted).

The sensor keeps the AppEUi and DevAddr configured. However, LoRaWAN configurations (channel, data rate…) and applicative configurations are lost.

Effects on the sensorThe CONF LED (red) and ASSN LED (green) blink at the same time briefly. All the applicative settings (for batches and reports) are deleted. The blinking is illustrated below this table.

Default configuration


A default configuration is set:

  • The device reports a "batch" of temperature / humidity from every 1 hour with a measure all 10 minutes.

The configuration of batch is :

Features Label (size= 3) Measure periodicity Transmission periodicity resolution
Temperature 0 10 minutes 1 hour 0.1°C
Relative Humidity 1 10 minutes 1 hour 1%
Battery Voltage 2 7 days 7 days 1mV

Every change made to the default configuration must comply with the legal duty cycle (for example, the most restrictive in the EU is 0.1%, which corresponds to approximately 1 frame per hour with SF12)

To decode the default "batch" is necessary to use this argument: 2 0,10,7 1,100,6 2,1,6 3,1,1 .

Measurement periodicity

The measurement periodicity depends on the minimum and maximum recording intervals, and the delta.

If the value of the minimum and the delta is 0, then the maximum value is the periodicity. However, if the value of delta is different than 0, then the periodicity is 1 second.

If the value of the minimum is different than 0, then this value is the same as the periodicity.
