Siglink is a temperature and humidity sensor working on the Sigfox network. Low energy comsumption is one of its notable qualities. This device will last for several years on a single battery. It is suitable for applications where long-term monitoring of temperature and humidity is required, such as greenhouses, server rooms, children’s rooms, wine cellars, etc. Thanks to the Sigfox network, there is no need for WiFi or GSM coverage. The sensor can be connected to the IoTpool platform, where data can be clearly displayed, alarms set, the transmission period changed and much more.

Temperature measurement

Precise temperature measurement at the installation site.

Humidity measurement

In addition to temperature measurement, the sensor is also able to measure humidity level, which can be useful at home, work, warehouse, etc.

Long life

The sensor has a very low power consumption. One AA battery 3.6V lasts up to 5 years.

Adjustable transmission period

The frequency of sending measured values can be configured using a Sigfox downlink message without the need to manipulate the sensor in any way. IoTpool makes the setting easy.

Easy to install

Connect the battery to the device, place it where you want to monitor temperature and humidity, and you’re done.

No internet connection is required

Thanks to the Sigfox network, on which the device works, no other connection is required. There is no need to be within range of WiFi, have a telephone operator’s signal, use SIM cards or connect via Bluetooth.

Compatible with IoTpool and other platforms

The sensor can be easily connected to IoTpool. Once you are connected it is possible to display and export received data, set alarms, change the transmission period or monitor the sensor status (battery, signal strength). After registering and activating, you will automatically receive Sigfox connectivity for the sensor. Moreover, it can also be connected to DevicePilot platform, the strong analytics tool to manage and visualize your data.
