It is based on the JY61 sensor, has Bluetooth or serial -connectivity, integrates a dynamic Kalman filter algorithm, an internal voltage -stabilizing circuit module, voltage 3.3v~5v. The only drawback is, that the -Bluetooth BLE is only compatible with android. The battery has a 150mA -capacity so it lasts for a long operation time.
