CPL03-NB -- NB-IoT Pulse Contact Sensor User Manual

The Dragino CPL03-NB is a (% style="color:blue" %)**NB-IoT Contact Sensor**(%%) for Internet of Things solution. It detects (% style="color:blue" %)**dry contact status, open time, open counts,**(%%) and then upload to IoT server via NB-IoT network.

30

31

The CPL03-NB will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculate last open duration. User can also disable the uplink for each open/ close event, instead, device can count each open event and uplink periodically.

32

33

CPL03-NB supports (% style="color:blue" %)**open alarm feature**(%%), user can set open alarm for instant notice. CPL03-NB supports (% style="color:blue" %)**Datalog feature**(%%), it can save the data when there is no NB-IoT network and uplink when network recover.

34

35

CPL03-NB is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.

36

37

CPL03-NB supports different uplink methods including (% style="color:blue" %)**MQTT, MQTTs, UDP & TCP**(%%) for different application requirement, and support uplinks to various IoT Servers.

38

39

CPL03-NB (% style="color:blue" %)**supports BLE configure **(%%)and(% style="color:blue" %)** OTA update**(%%) which make user easy to use.

40

41

CPL03-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long-term use up to several years.

42

43

== 6.2 How to Connect Dry contacts or Wet Contacts ==

1181

1182

1183

CPL03-NB can only be connected to dry contacts by default, and the wiring method is to connect the two ports of dry contacts to the VDD pin and pulse input pin of CPL03-NB respectively.

1184

1185

If you want to connect a wet contact, you need to change the original wiring method. The wiring method is that the GND of the wet contact is connected to the GND of CPL03-NB, and the pulse output is connected to the pulse pin, but the pulse output voltage of the wet contact must be less than 3.6V.

1186

1188

== 6.3 What is the maximum total number of pulses for CPL03? What happens after the maximum total number of pulses is reached? ==

The maximum total number of pulses for CPL03 is three bytes FF FF FF (16,777,215).

1192

The count is reset when the maximum total number of pulses is reached.
