IoT Long Range Wireless Multi Channel Dry Contact Closure Transmitter.

IoT Long Range Wireless Multi Channel Dry Contact Closure Transmitter
Introducing  Long Range IoT Wireless Multi Channel Dry Contact Closure Push Notification Transmitter, boasting up to a 2 Mile range using a wireless mesh networking architecture. This IoT Wireless Multi Channel Dry Contact Closure Transmitter detects up to 7 push inputs with low latency and sends out a frame, while sleeping the rest of the time to minimize power consumption. Optionally, user can also set a sleep duration which will make sure the transmitter wakes after a certain time and sends out a frame (even when no push input is detected). This device is frequently used for contact closure push notification applications. This IoT Wireless Multi Channel Dry Contact Closure Transmitter can be powered externally as well. The IoT Wireless Multi Channel Wet Contact Closure Transmitter can be powered externally or use built in batteries. This device includes a voltage detection switch, automatically switching to batteries if external power is lost. The data packet includes system voltage information. System voltage values of 1,000 or higher indicate external power it working. Please note that leaving the contacts closed for an extended period of time will drain the battery.
Powered by just 2 AA batteries and an operational lifetime of 300,000 wireless transmissions, a 3 years battery life can be expected depending on environmental conditions and the data transmission interval. Optionally, this sensor may be externally powered.
IoT Security
We take IoT security very seriously, which is why we encrypt every IoT sensor, gateway, modem, and device in the 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
long-range wireless IoT sensors use the DigiMesh® protocol from 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. IoT sensors are capable of a 2-Mile line-of-site communication distance with the included antennas and up to 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 wireless transmitters into your own software. This allows integration of 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 modems. Send data to popular cloud platforms such as Microsoft® Azure® IoT, Losant, and MQTT using Micro Gateways. We can also help get data from 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 7 Channel Push Notification Sensor makes it an affordable choice which exceeds the requirements for most of the industrial as well as consumer market applications.
Transmission Interval
This device sends data periodically, based on user-preset timing intervals.
This device sends data when a state change on any of the contact closure inputs is detected.
Sensor Data Overview
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 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 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 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 IoT sensor, you have control over longevity. Please note the 500,000 transmission rating is for premium alkaline batteries. ships all sensors with premium Lithium batteries, which include a 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.
