Тема: Wireless temperature/humidity sensors Eurosens DTS/DES

Are used in the remote temperature monitoring when it is difficult to install wired temperature sensors (refrigerator compartments of trucks, industrial fridges etc).

For measurement we need at least a pair of devices : sensor (transmitter) and receiver.

Sensor doesn't have any wires and is powered from long-life onboard battery during several years.

One receiver can poll up to 10 sensors and sends results to the GPS trackers via RS485 interface using LLS protocol.

For setting up temperature and humidity sensors Eurosens DTS configurator is used.

Connect Eurosens DTS receiver to the laptop using Eurosens Destination 02 USB-RS485 adapter or any compatible.

Choose the COM port of connected adapter and click Connect

Configurator connects to the receiver. Click the button “Find device”.  Receiver is set to find wireless temperature sensors nearby and show its current values.

In the colums you can see the temperature, humidity, illumination, battery voltage and the level of radio signal.

To make sensor settings we have to turn it into configuration mode. Touch magnet icon on its casing by magnet for 1 second. Central LED will light up.

Turn sensor into congiration mode with this button. All sensor data become zero. Make sensor search again and we’ll see our only sensor in the configuration mode. Now you can change its settings.

In the Sensor field you can set the number of sensor, in the connection order to the receiver. This number is reflected in the RS485 data address. Number one means you’ll see this sensor data in LLS protocol of RS485 interface under first address.
Temp_offset parameter is permanent temperature offset of the data and can be used for the calibration of the temperature sensor.

We can change the source of temperature data by changing Temp_source setting. It is possible to choose one of three sources : temperature sensors are built-in in the humidity sensor, radiolink module and central processor module. By default humidity sensor is the main source of data but some sensors doesn’t have the humidity sensor option so you can choose one of the rest sources.

Update parameter defines how often sensor sends the data. More frequency of update leads to faster battery drain.

Receiver collects data from all available temperature sensors. To divide receivers/sensors into groups we can use the parameter RF network mask. Receiver with network mask №2 doesn’t read the sensors with network mask №1. To assign the sensor with the new network mask we only need to make its settings with the receiver with new network mask already assigned in settings.

Re: Wireless temperature/humidity sensors Eurosens DTS/DES

To set up new parameter value we should click Write button.

After setting up procedure is completed we switch off  the configuration mode in sensor. To do that touch the magned icon by magnet again for 5 seconds. Central LED switches off.

Finally, click the button  “Disable configuration mode” in the configurator. Receiver will poll all sensors again and show its values.
