New W2-P5202D3 Wristband Beacon

We have the new W2-P5202D3 Wristband Beacon in stock.

It advertises iBeacon, Eddystone and acceleration. Rechargeable via USB. Supports always, button triggered (for SOS) and motion triggered advertising.

The app allows you to configure up to 6 advertising slots that can include iBeacon, Eddystone (UID, URL and TLM), acceleration and information (device name, MAC address, battery level).

Sensor Beacon Matrix Updated



We offer a range of sensor beacons but what each beacon actually senses or detects is buried deep in the respective beacon descriptions.

As we have recently added new sensor beacons, we have updated our downloadable pdf showing what each beacon can detect.

If you want to know how you might use these beacons, take a look at our articles on Beacon Proximity and Sensing for the Internet of Things (IoT) , Using Bluetooth LE and Using Bluetooth LE Sensors.



New Meeblue M52-SA in Stock

There’s a new manufacturer, Meeblue, offering highly capable sensor beacons at competitive prices. We have the M52-SA in stock:

This beacon has temperature, humidity and acceleration sensors and offers two configurable channels and a sensor data channel. It can advertise iBeacon, Eddystone UID, Eddystone URL or custom data in each channel simultaneously.

The acceleration is only used for motion triggered broadcast. Broadcast can also be triggered by the hidden button in the centre of the beacon that also acts as an on/off switch.

The beacon can also be used as a temperature/humidity logger storing up to 80985 records with a configurable storage interval of 1-240 minutes.

Use of the Nordic nRF52 ensures a long battery life.

New Bluetooth Sensors

We have two new sensor beacons in stock. The iBS03TP is a waterproof temperature beacon with a 2m probe measuring -50C to 150C with an accuracy +- 0.5C.

The iBS02M2 measures on/off. This can be a switch or a voltage (0.5v to 50v is ‘on’).

The small PCB with a USB connector plugs into the main unit USB. The terminal block is used connect to anything that provides a switched or voltage output. This makes this beacon suitable for detecting a wide range of on/off scenarios.

Understanding Sensor Beacon Accelerometer Data

In this post we will take a look at data from the INGICS iGS01RG beacon.

The x axis is time. You can see the x, y and z values, every 100ms, over time. The y axis is normalised between -1 and -1 for use in our SensorCognition Edge device. The chart is for when the beacon has been moving, followed by a stationary period. Notice how the orange line continues to show acceleration even though the beacon isn’t moving. This is caused by gravity.

In this chart the beacon has been flipped over and the orange line now shows a constant negative acceleration.

A good thing about the presence of a constant offset in one of the x y z inputs is that it can be used to help determine the orientation of the beacon. The less desirable aspect is that the offset significantly complicates using the x y z to determine types of movement such as human gestures.

Such complex data problems are more easily solved using AI machine learning than trying to write a traditional algorithm to make sense of the data.

Here’s an example of output from a SensorCognition Edge device trained with up and down movement and left and right movement. In this case, the output 227 is showing the beacon is moving left and right.

New H4 Sensor Beacon

We have the new Moko H4 sensor beacon in stock.

This beacon transmits up to 6 channels including iBeacon, Eddystone (TLM, UID, URL), temperature/humidity and information (device name, MAC address, battery level ).

The sensor is held outside the beacon in a small cage that allows the beacon to be waterproof to IP66. A unique feature is logging that allows storing and export of up to 4000 historical sensor values:

Sensor Triggered Advertising

Most of our sensor beacons with accelerometers offer motion triggered broadcast. That is, they can be set up to advertise when the beacon is moving. This can be used for motion detection or, in some scenarios, as a mechanism to significantly conserve battery life.

Some beacons such as the iB001M, iB002M and Minew range with buttons can be set to only advertise when there’s a double press of the button. This can be used for SOS type scenarios.

The S1 temperature humidity beacons can also be set to advertise when the temperature or humidity goes above or below a value. This is useful for alarm type situations.

S1 Beacon

While triggered broadcast provides for these usecases and extends battery life, it should be remembered that because the beacons are not advertising all the time, there’s no way of knowing their location (in RTLS situations) or indeed if the beacon is working (e.g. the battery might be flat). Beacons such as the INGICS range advertise all the time and send different advertising when a button is pressed or the temperature/humidity changes. This allows for ‘I am still here’ functionality at the expense of shorter battery life.
