PEEK Sensor
Read full descriptionHide full description
An application to connect to the PEEK sensor of PEEK GmbH via Bluetooth Low Energy. Battery level - the app shows the current battery level of the PEEK sensor. Firmware update - the application is needed to transfer important and safety-relevant updates to the PEEK sensor Additional features - the application displays the status of additional functions of the PEEK sensor and also provides additional information that is not directly displayed on the PEEK sensor. Alert Method “Voltage level” - the app allows you to change the voltage level PEEK settings according to your working environment. Alert Method “Adaptive System” - the app is setting a default sensitivity level and is able to reset the sensitivity level back to default. The full functionality of the application can only be viewed in conjunction with an active BLE connection to a PEEK sensor.
