GasBuster
Read full descriptionHide full description
GasBuster connects with all gas sensors within your reach and displays the measured values (gas concentration and temperature) as well as vendor ID and serial number of these sensors. If there is a connection between the gas sensor and your smart phone the connectivity icon turns blue. With the wiping function you can jump between the individual gas sensors back and forth. The dots indicate the amount of gas sensors that are connected. When a gas sensor loses the connection for 15 seconds the screen switches to the next sensor or the home screen will be displayed when no other sensors are connected. GasBuster is compatible with all gas sensors from Microtronics.
