WebMar 13, 2024 · The ADXL335 datasheet gives the device sensitivity for a supply voltage of 3 V. If we operate this sensor with a 3.6 V power supply, its sensitivity will be 360 mV/g. Accelerometer datasheets also specify the sensitivity variation with temperature as a percentage shift per °C. WebFeb 26, 2024 · The sensitivity of the pacing unit is set at its most sensitive level (lowest value), and is then decreased (higher values) gradually. The setting at which the pacemaker fails to sense and begins pacing competitively with the patient’s intrinsic rhythm is called the sensing threshold . For demand pacing, the sensitivity should be set at a ...
