C1D2 Industrial IoT Wireless Water Detect Sensor Datasheet

Device Overview

NCD’s C1D2 certified long-range wireless water detection sensors are the first designed specifically for hazardous environments. Certified for C1D2 Groups A, B, C, and D, they are suited for areas with explosive gases, dust, fibers, or flammable vapors, including substances like Acetylene, Hydrogen, Gasoline, and Methanol. These sensors are ideal for use in chemical plants, oil refineries, paint shops, mills, and other facilities handling flammable materials.

Featuring an integrated antenna and up to a 2-mile range, the sensor uses a 900MHz 128-Bit AES encrypted transceiver to send data at customizable intervals. It sleeps between transmissions to save power, waking every 15 minutes or when a wet/dry condition is detected. This ensures regular updates and immediate alerts, with a battery life of up to 10 years depending on conditions and settings.

The sensor includes a 4.5-meter probe cable, transmitting wet or dry status changes for applications like water leak detection. It is ideal for preventing water damage in buildings or monitoring drainage in critical areas. Applications include detecting floods, leaks from water heaters, frozen pipes, or low-water conditions in sensitive areas like factory floors and machinery.

NCD’s sensor ecosystem integrates seamlessly with platforms like AWS®, Microsoft Azure®, or private MQTT brokers using Node-RED. This allows secure, private data handling or cloud integration with minimal effort, making it one of the most versatile and reliable solutions on the market.

Status LED

The Status LED is used to indicate errors or other sensor diagnostics.

LED blinks once – Message was sent successfully and no error in last sensor read as well in data transmission.

LED blinks twice and then one more time – Message was sent successfully but there was an error in last sensor read.

LED blinks thrice – MCU is having issue communicating with the radio module.

Power Requirements and Expected Battery Life

Power Requirements

This Sensor is battery powered

Powered by AA batteries (NCD recommends Energizer L91 batteries).

While changing the batteries:

  1. Turn off the sensor
  2. Only use new L91 batteries
  3. Checkout the polarity marking on the battery holder and batteries
  4. Replace all six batteries with new L91 batteries. Do not mix old and new batteries
  5. Batteries should not be replaced in fire-risky areas
  6. Do NOT install rechargeable batteries
