Our long range wireless enterprise series sensors are an easy to use and reliable start to any data aggregation application. This video will demonstrate how they work, what they do, and how to use them.
IoT Long Range Wireless Acceleration and Impact Detection Sensor
Introducing Qatalytic’s Store Long Range IoT Wireless Impact Detection Sensor, boasting up to a 2 Mile range using a wireless mesh networking architecture. This device incorporates a precision acceleration sensor for measuring acceleration changes. Utilizing the interrupt feature of this sensor, it is able to minimize power consumption by waiting for the interrupt from the sensor.
Configure the Impact Detection condition (interrupt settings) using configuration mode. This impact detector offers many configuration parameters, including acceleration range, data rate, interrupt duration, and interrupt threshold. Interrupt duration is dependent upon data rate. It is the duration for which an interrupt condition has to hold to generate a system interrupt and initiate data transmission to a nearby receiver. Interrupt threshold is dependent upon acceleration range, and is the acceleration in g which (if exceeded) causes the interrupt to fire. Note the absolute value of actual g reading is compared, therefore it works for both positive and negative acceleration exceeding threshold.
Interrupts are fired only when the acceleration (absolute value) read form the sensor exceeds the threshold in the positive direction. All interrupts are combined with an OR gate. This allows impact detection (system interrupt) if an interrupt occurs for any axis (OR condition). User can also configure a delay time in seconds which disables the interrupt for that amount of time after a successful interrupt. This enables the user to make sure that the sensor does not drain its battery (with continuous transmissions) if an interrupt condition persists or a wrong condition is accidentally programmed. This time is also used to send a periodic packet to a receiver with latest available data.
The device also sends two extra samples with the sample which caused interrupt. This enables the user to have a history of acceleration data prior and after the interrupt. In a normal scenario, it will send 1 sample (n-1) prior to the interrupt sample (n) and 1 sample after the interrupt (n+1). However, if the data rate is too slow, the sensor does not wait for n+1 packet to arrive so as to save battery and instead sends 2 old samples (n-2, n-1) along with the third sample (n) which fired interrupt. It may happen that the duration and sleep delay combination is such that no old sample was saved after the last interrupt and at the time of interrupt the device may contain only 1 sample. In that case it sends 2 old samples from the last transmission along with third sample (n) being the interrupt sample. In case it has 1 old sample (n-1) and 1 interrupt sample (n), it will send the first sample (n-2) from the previously transmitted data.
Powered by just 2 AA batteries and an operational lifetime of 300,000 wireless transmissions, a 10 years battery life can be expected depending on environmental conditions and the data transmission interval. Optionally, this sensor may be externally powered.
We take IoT security very seriously, which is why we encrypt every IoT sensor, gateway, modem, and device in the Qatalytic Store Enterprise product line. Encryption is much easier to manage than you might expect, as the encryption does not get in the way of using the device. We include a standard 128-Bit AES Encryption key with every device or we can help you integrate a new encryption key into all of your devices. All hardware devices must use the same encryption key. Once the keys are set, the hardware manages the rest for you, 100% in the background.
Wireless Range and Protocol
Qatalytic Store long-range wireless IoT sensors use the DigiMesh® protocol from Digi.com. DigiMesh® was designed by THE industrial leader in secure wireless communications for industrial applications. DigiMesh® automatically hops data from gateway to gateway until it arrives at the desired destination. Qatalytic Store IoT sensors are capable of a 2-Mile line-of-site communication distance with the included antennas and up to a 28-mile range when using high-gain antennas.
Your IoT Sensor Data Belongs to You!
Your data belongs to YOU and it’s up to you to decide where you want your IoT sensor data to arrive. Don’t be bogged down by the limitations of proprietary cloud solutions, post the data where you need it most. We offer an open communications protocol so you can integrate Qatalytic Store wireless transmitters into your own software. This allows the integration of Qatalytic Store IoT sensors into any control system or gateway you could ever imagine. Send data to a PC, Mac, or Linux computer, or a Raspberry Pi using Qatalytic Store modems. Send data to popular cloud platforms such as Microsoft® Azure® IoT, Losant, and MQTT using Qatalytic Store Micro Gateways. We can also help get data from Qatalytic Store wireless IoT sensors to embedded platforms such as Arduino. We also offer sample code for Microsoft® Visual Studio, Node-RED, LabVIEW®, and Python. Our documentation fully breaks down the packet structure, so integration into other languages is possible. We may even be able to help, so please feel free to contact us if you are working with a platform not mentioned here.
The long range, price, accuracy, battery life and security features of Wireless Impact Detection Sensor makes it an affordable choice which exceeds the requirements for most of the industrial as well as consumer market applications.
NOTE: The current version of this sensor does not support the inbuilt temperature sensor.
This device sends data when input thresholds exceed user-defined preset limits.
Sensor Data Overview
Qatalytic Store IoT Sensors send a lot more than just sensor data. For instance, a unique serial number is sent so you can always identify a particular sensor on the network. A Node ID is also included, which is a single byte of data that you can use for anything, such as the floor of a building or to help identify which group a sensor belongs to. Also included in the data packet is a firmware version, battery level, and sensor type. This allows your software to positively identify and manage the health of Qatalytic Store IoT wireless sensors. While signal strength data is also available, it is handled in a different way and is not included in the sensor data packet (but rest assured, signal strength data for each sensor is available). Please see the Resources tab to see detailed information on the data structure of this device.
How long Will the Batteries really Last?
Most Qatalytic Store IoT Sensors are rated for 300,000 to 500,000 transmissions until the batteries become so weak they are unreliable. You could spread these transmissions out over a 10 year period and send 50,000 transmissions per year. This would allow up to 136 transmissions per day, or about 5 transmissions per hour (for a 500K sensor, or 3 per hour for 300K sensor). If you only need the batteries to last 3 years, you could send 166,666 transmissions per year, or about 456 transmissions per day (about 19 transmissions per hour for a 500K sensor). As you can see, battery life is really up to you. By altering advanced settings in the Qatalytic Store IoT sensor, you have control over longevity. Please note the 500,000 transmission rating is for premium alkaline batteries. Qatalytic Store ships all sensors with premium Lithium batteries, which include an ultra-wide temperature range that typically lasts in excess of 600,000 transmissions for some sensor types. These batteries weigh less than half of alkalines, and they work in the freezer! A word of caution though, putting a sensor in configuration mode will drain the batteries very quickly. It’s important to configure your sensors and exit configuration mode as soon as possible or use a external power supply during configuration (if supported by the sensor). The table below indicates how many Transmissions Per Hour (TPH) your can expect from different sensors over a lifespan of up to 10 years.
|Battery Life:||3 Months||6 Months||1 Year||2 Years||3 Years||5 Years||10 Years|
|300K Sensor||136 TPH||68 TPH||34 TPH||17 TPH||11 TPH||6 TPH||3 TPH|
|400K Sensor||180 TPH||90 TPH||45 TPH||22 TPH||15 TPH||9 TPH||4 TPH|
|500K Sensor||228 TPH||114 TPH||57 TPH||28 TPH||19 TPH||11 TPH||5 TPH|
|600K Sensor||272 TPH||136 TPH||68 TPH||34 TPH||22 TPH||13 TPH||6 TPH|
TPH = Transmissions per Hour
How Do I Change Settings and Examine Raw Sensor Data?
Using our long-range USB wireless modem, users can expect easy operation over a virtual COM port at 115.2K baud. Simply open the virtual COM port of the USB modem and watch data stream in. Optionally, we offer a Wireless receiver that operates over Ethernet. Data from Qatalytic Store sensors will appear over TCP/IP on port 2101. Simply open a TCP/IP socket, port 2101, to the IP address of the Ethernet modem and see your data stream into your local area network. We have developed LabVIEW® software for each sensor to change advance sensor settings using both Ethernet and USB modems. Alpha Station also allows display of sensor readings as well as limited configuration (this feature is still in development). Of course gateways are also available for sending data to popular cloud platforms such as Amazon® AWS® IoT, Microsoft® Azure® IoT, and Losant (more information below). We take software samples seriously, so be sure to to check out the “Resources” tab to see code samples for Raspberry Pi, Visual Studio, LabVIEW®, Arduino, Python, and more.
