										<content:encoded><![CDATA[<p>CPN01 is an NB-IoT dry contact sensor. It detects the open/close status and transmits the information to the IoT server via the NB-IoT network. The user can see the dry contact status, open time and number of open contacts on the IoT server.</p>
<p>The CPN01 will periodically send data daily and for each dry contact operation. It also counts the open contact time and calculates the duration of the last open contact. Users can also disable the uplink for each open/close event, instead the device can periodically count each open event and uplink.</p>
<p>CPN01 has an Open-Alarm function, the user can configure this function so that CPN01 sends an alarm if the contact has been open for more than a certain time.</p>
<p>CPN01 is intended for outdoor use. It has a waterproof case and an industrial-grade battery for operation in low and high temperatures.</p>
<p>Narrowband Internet of Things (NB-IoT) is a standards-based Low Power Wide Area (LPWA) technology designed to enable a wide range of new IoT devices and services. NB-IoT significantly improves user device power consumption, system throughput, and spectrum efficiency, especially in deep coverage environments.</p>
<p>CPN01 supports various uplink methods including TCP, MQTT, UDP and CoAP for different application requirements.</p>
<p>The CPN01 is powered by an 8500 mAh Li-SOCI2 battery. It is intended for long-term use up to 5 years. (Actually, the battery life depends on the usage environment, update period and uplink method.)</p>
<p>To use the CPN01, the user must check whether there is NB-IoT coverage in the field and the Nb-IoT bands supported by the CPN01. If the local operator supports it, the user needs to get an NB-IoT SIM card from the operator and install it in the CPN01 to get connected to the NB-IoT network.</p>
<p>features:</p>
<p>NB-IoT bands: B1/B3/B8/B5/B20/B28 @H-FDD</p>
<p>Open/close detection</p>
<p>Open/close statistics</p>
<p>Battery level control</p>
<p>The uplink and the open/close event are periodically turned on</p>
<p>Data log function</p>
<p>Outgoing line periodically</p>
<p>Downlink to change configuration</p>
<p>Wall mounting</p>
<p>Outdoor use</p>
<p>Ultra-low power consumption</p>
<p>AT Commands for changing parameters</p>
<p>Micro SIM card slot for NB-IoT SIM</p>

										<content:encoded><![CDATA[<p>CPL01 is it <strong>LoRaWAN contact sensor</strong> . It detects open/close status and connects to IoT server via LoRaWAN network. user can see dry contact status, open time, number of open on IoT server.</p>
<p>The CPL01 is powered by a Li-SOCI2 battery <strong>with a capacity of 8500 mAh</strong> , designed for long-term use up to 10 years. (Actually battery life depends on usage environment and update period.)</p>
<p>The CPL01 will periodically send data daily as well as for each dry contact operation. It also counts the open contact time and calculates the duration of the last open contact. Users can also disable the uplink for each open/close event, instead the device can periodically count each open event and uplink.</p>
<p>CPL01 has an open alarm function, the user can configure this function so that the device sends an alarm if the contact has been open for a certain time.</p>
<p>Each CPL01 comes pre-loaded with a set of unique LoRaWAN registration keys, register these keys to the LoRaWAN server and it will connect automatically after power on.</p>

										<content:encoded><![CDATA[<p>LDS03A is it <strong>LoRaWAN door open/close sensor</strong> . It detects open/closed door status and connects to IoT server via LoRaWAN network. the user can see the status of the door, the duration of the open time, the number of open doors on the IoT server.</p>
<p>The LDS03A is battery powered <strong>Li-SOCI2 with a capacity of 8500 mAh</strong> . It can be used up to 10 years.</p>
<p>The LDS03A will periodically send data every 2 hours and for every door open/close action. It also counts the time the door was opened and calculates how long the door was last opened. Users can also disable uplink for each open/close event, instead LDS03A can periodically count each open event and uplink.</p>
<p>LDS03A has <strong>the Datalog function</strong> , it records the open/close event and the user can retrieve the history from LoRaWAN.</p>
<p>LDS03A has <strong>open alarm function</strong> , the user can configure this function so that the device sends an alarm if the door has been opened for a certain period of time.</p>
<p>The LDS03A is intended for outdoor use. It has a waterproof case and an industrial-grade battery for operation in low and high temperatures.</p>

										<content:encoded><![CDATA[<p>The CPL03-LB is the solution <strong>LoRaWAN contact sensor</strong> for the Internet of Things. It detects dry contact status, operating time, number of open data and then uploads to IoT server via LoRaWAN wireless protocol.</p>
<p>The CPL03-LB will periodically send data daily as well as for each dry contact operation. It also counts the contact opening time and calculates the duration of the last opening. The user can also disable the uplink for each open/close event, instead the device can periodically count each open event and uplink.</p>
<p>The LoRa wireless technology used in the CPL03-LB allows the device to transmit data and reach extremely long distances at low data rates. It provides ultra-long range spread-spectrum communication and high immunity to interference while minimizing current consumption.</p>
<p>CPL03-LB <strong>supports open alarm function</strong> , user can set open alarm for instant notification. CPL03-LB <strong>supports the Datalog function</strong> , it can save data when there is no LoRaWAN network and connect when the network is restored.</p>
<p>CPL03-LB is intended for outdoor use. It has a waterproof case and an industrial-grade battery for operation in low and high temperatures.</p>
<p>CPL03-LB <strong>supports BLE configuration and wireless OTA update</strong> , which makes it easy for the user to use.</p>
<p>CPL03-LB is powered <strong>from a Li-SOCI2 battery with a capacity of 8500 mAh</strong> , designed for long-term use up to 5 years.</p>
