Telemetry collars with flexible perovskite solar panels are created to support the life-lasting monitoring of animals. Collars consist of injecting printed perovskite solar panels covered by transparent epoxide and combined with a GPS fixing chip and LoRa data transmitter. Two innovative collars were put on two European (male and female) bisons at Styr hunting enterprise. The GPS coordinates were saved in the EEPROM memory in the collar and transmitted through the LoRaWAN communication protocol to the cloud and created a database. The database provides data to Grafana open-source service, enabling flexible visualizations of forms from multiple data sources. As a result of this, online monitoring of wildlife is established without the need to change the batteries in telemetry collars worn on animals.
