4. AIM OF THE DOCUMENT

The aim of this document is to describe the autonomy performance of the BeanDevice SmartSensor and

ProcessSensor product line in streaming and streaming packet mode.

This document is not intended to show with an extreme precision the autonomy you can expect from our

BeanDevice. But you will have an estimated autonomy of the Beandevice operating in an environment

with an ambient temperature.

Please note that these computed values can change, depending strongly on your environment.

By the way, you will find information about interferences on other BeanAir documents.

5. TESTS OVERVIEW

The Beandevice autonomy is given with:

o Different data acquisition modes and different sampling rate

o Datalogger feature enabled/disabled

o Two different RF Power +18 dBm and +15 dBm.

Each BeanDevice was powered by an internal battery.

4 BeanDevices were used during these tests:

SmartSensor AX-3D (+/- 10g)

SmartSensor AX-3D (+/- 2g)

SmartSensor HI-INC 30 Bi-axis

SmartSensor HI-INC 15 Mono-axis

Figure 1: Global presentation of the system

All the tests were made in continuous monitoring mode.

IMPORTANT:

Note that each autonomy measure was made with one specific BeanDevice.

The number of BeanDevices present on each BeanGateway can reduce your BeanDeviceautonomy, due to the fact that some BeanDevices of the network can lose some data

informations if the network global bandwidth is exceeded.

6. OPERATING TEMPERATURE OF 23C

We measured the autonomy of the BeanDevices at a room temperature of 23C.

We used the 2 most common RF power transmissions: +18 dBm and +15 dBm.

7. CONCLUSION OF THE TESTS

Sampling rate

The BeanDevice autonomy is inversely proportional to the sampling rate confgured on yourBeanDevice

The Beandevice autonomy will increase if you set the sampling rate at 10 Hz (10 measures persecond) than at 1000 Hz (1000 measures per second).

Streaming Packet

mode Vs

Streaming mode

The BeanDevice autonomy is higher in streaming packet mode than in streaming mode, due tothe continuous transmissions of the Streaming Mode.

If you modify the data acquisition mode Streaming to Streaming packet, the Beandeviceautonomy will increase by 5%

Datalogger

feature

The DataLogger feature can influence the BeanDevice autonomy;

When the datalogger is activated , the Beandevice autonomy will decrease by 15% ;

RF Power

RF Power can influence the Beandevice autonomy; If you modify the RF Power 18dBm to 15dBm , the Beandevice autonomy will increase by 2%
