IoT Long Range Wireless Acceleration and Impact Detection Sensor
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 NCD’s Long Range IoT Wireless Impact Detection Sensor, boasting up to a 28 Mile range using a wireless mesh networking architecture. It incorporates a STMicro LIS3DH acceleration sensor for measuring acceleration changes. Utilizing the interrupt feature of this sensor, it is able to minimize power consumption by making most of the components go to sleep while waiting for the interrupt from the sensor.
User can configure the Impact Detection condition (interrupt settings) using the configuration mode. User can configure 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 it is the acceleration in g which if exceeded causes interrupt to fire. Note that the absolute value of actual g reading is compared with it 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 accidently 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 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.
With an open communication protocol this sensor can be integrated with just about any control system or gateway. Data can be transmitted to a PC, a Raspberry Pi, to Microsoft Azure® IoT, or Arduino. Sensor parameters and wireless transmission settings can be changed on the go using the open communication protocol providing maximum configurability depending on the intended application.
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.
Receiving Data From Long Range IoT Wireless Acceleration and Impact Detection Sensor
This Long Range IoT Wireless Acceleration Impact Detection Sensor device sends data periodically, based on user-preset timing intervals. Data transmissions include battery level, signal strength, payload, firmware version, sensor type, and device serial number. Please see the Resources section to see detailed information on the data structure of this device. This Long Range IoT Wireless Vibration Temperature Sensor is a wireless transmitter needs a receiver. There are many options available for receiving data from NCD transmitters. We highly recommend using our USB Modem (available during purchase) so you can monitor this device and use our LabVIEW software for changing device settings. Using our long-range USB wireless modem, users can expect easy operation over a virtual COM port at 115.2K baud. Optionally, we offer a Wireless receiver that operates over Ethernet. Data from NCD 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 in to your local area network.

900HP-S3B Industrial Wireless Mesh
Long-Range Wireless Mesh networking is our favorite of all wireless communication technologies. This is the ONLY communications technology NCD recommends on the factory floor, operating at a safe 900MHz. Mesh technology will hop data from one location to another to reach its intended destination, users do not need to do anything other than make sure wireless modules stay within hopping range of each other. We use the Digi 900HP-S3B module in our products, as this is the best the industry has to offer. With a 2 mile range between modules and up to 8 hops, it is possible to cover 16 miles of wireless territory using this technology. Using high-gain antennas, this module is capable of communicating to a remote module up to 28 miles away.
