![]() Make sure that proper logic levels are matched, especially with the digital interfaces. Large-scale modern concrete retaining wall blocks for large commercial installations & public works. These different modes can make accelerometers well suited for battery powered applications. G-Force is part of the dry cast collection. The current consumption can vary depending on the settings (e.g., power saving mode versus standard operating mode). The required current typically falls in the micro (µ) or milli-amp range, with a supply voltage of 5V or less. Pulse-Width Modulation (PWM) - Accelerometers that output data over pulse-width modulation (PWM) output square waves with a known period, but a duty cycle that varies with changes in acceleration.Īccelerometers are generally low-power devices. The record for highest G-force on a roller coaster is 6.3, and it’s only manageable because it lasts just a few seconds. These tend to have more functionality and be less susceptible to noise than analog accelerometers. What’s The Magic Number As we’re just standing at sea level, a standard 1 G of G-force is acting on us. These are generally less expensive than digital accelerometers.ĭigital - Accelerometers with a digital interface can either communicate over SPI or I 2C communication protocols. An ADC on a microcontroller can then be used to read this value. These values generally fluctuate between ground and the supply voltage level. Communication InterfaceĪccelerometers will communicate over an analog, digital, or pulse-width modulated connection interface.Īnalog - Accelerometers with an analog interface show accelerations through varying voltage levels. As always, read the datasheet to ensure proper connections are made. For most accelerometers, the basic connections required for operation are power and the communication lines.
