AKKR8 contains a motion sensor with an accelerometer, useful for monitoring transports, for predictive maintenance of machines, for factory automation and so on.
Measure movement and acceleration
It has a 6-axis motion tracking sensor that combines a 3-axis gyroscope, and a 3-axis accelerometer. The sensor is a very power efficient sensor, made for IoT. All sensors are factory-calibrated.
The gyroscope has a programmable full-scale range of ±250 dps, ±500 dps, ±1000 dps, and ±2000 dps. The triple-axis gyroscope measures movement in X-, Y-, and Z-axis. The gyroscope is an angular rate sensor.
The triple-axis accelerometer features an X-, Y-, and Z-axis accelerometer with a programmable full-scale range of ±2g, ±4g, ±8g and ±16g. With the AKKR8 board we can program limits, that can trigger interrupts, or what we prefer to call Wake-on-motion interrupt. This is perfect for low power operations as it does not need the AKKR8 processor to be operational and consuming battery. The sensor has programmable interrupts that can wake up the AKKR8 if movement exceeds a programmable threshold.
The sensor has an embedded temperature sensor, thus reducing the cost of temperature measurements in large scale deployments.
The sensor can be used in any application where motion tracking or accelerometer tracking is needed. For example counting machine hours, detecting a discrepancy in movement, monitoring mobile diesel tanks at construction sites, monitoring other assets in an industrial area.
Normal state and alarm state
All sensors can have a normal state and an alarm state. Let us use an example. You have a machine that is normally vibrating slightly. The device wakes up every hour, reads the value and stores is it the device. Uploading the values will be done once a day. The machine has its normal vibration pattern in X, Y and Z directions. If the device detects a movement above this level, it will wake up the device, and enter an alarm state. In the alarm state it can for example shut down the machine with the relay output and make sure that it immediately uploads the alarm value to the IoT-platform. In the alarm state it can be set to report more frequently as well, for example every minute.
Smart power management
All analogue sensors needs to be supplied from an external power supply. These are normally not suited for battery operated applications. With some clever magic in our sensor we can use the built in GPIO port to initiate your sensor only when it needs to be on, we automatically shut it off after we have read the value. The time to stabilise the sensor reading can be carried out as well.
