Getting Started
The CS1010 is a long-range, low-power water leak sensor supporting LoRaWAN or
Coralink wireless protocols. The sensor supports configurable real-time
notifications and/or regular reported statistics.
Deploy the sensor in hard-to-reach places: under water tanks, basements,
bathrooms, attics. The base unit detects the presence water with probes on top
and bottom of the device. Place the sensor anywhere there is a substantial
risk of damage due to leaks or flooding.
What’s In the Box
The CS1010 leak-sensor package includes the following:
- Leak Sensor LoRa
- Identity Information
The sensor is self-contained and is watertight. Once activated, the sensor can be placed in areas where potential leaks or flooding are a concern. See Installation for details and to learn more about proper placement.
Attaching to the Network
Once the device is removed from the packaging, it can be activated by pressing the set button. The device will activate, blinking orange four times and begin issuing join requests. The LED status indicators is shown in the figure below.
Figure 2 CS1010 LED Status Indicators
Periodically, the CS1010 will blink red twice when joining the network.
Assuming the device is properly registered on an available network and in
range, it should connect. It will blink green four times indicating it has
joined.
Once joined, the leak sensor can be tested by placing the device in a wet dish
or touching the top sensors with a wet finger. By default, the unit will
generate leak detect and clear events to notify the application. Reminders and
other configurations options are available.
Note : If the CS1010 has not joined within a few minutes, the LED will
stop blinking, though it will continue try to join: ten times in the first
hour, then longer intervals over the first week until finally attempting once
every 12 hours. This is done to conserve battery power when the network is not
available for long periods of time. You may reset the join schedule by
performing a Network Reset on the device, see User Interface.
To learn more about the capabilities of the CS1010, see Configuration and
Integration.
User Interface
Set Button
The CS1010 user interface consists of the LED status indicators (Figure 2)
and the set button located on the underside of the device. Pressing the button
quickly will indicate the current network status discussed previously.
Figure 3 – Performing Network or Factory Reset on the Leak Sensor
Holding the button will perform a network or factory reset:
- Network Reset – Press and hold the SET button for 10 seconds, but less than 25, then release. The device will reset all LoRaWAN Settings, which does not affect device operation or configuration. Following reboot, a reset event uplink (confirmed) will be sent upon rejoining the LoRaWAN network.
- Factory Reset – Press and hold the SET button for > 25 seconds, then release. The device will reset all parameters to factory defaults. Following reboot, a Factory Reset event uplink (confirmed) will be sent upon rejoining the LoRaWAN network.
Status Indicators
A single button press will indicate the network status. The following table
summarizes all the LED indicators.
LED
|
Status
---|---
Fast Red Blink Two (2) Times| Not Joined
Fast Green Blink Four (4) Times| Joined
Slow Red Blink Two (2) Times| Joining Network
Slow Green Blink Four (4) Times| Joined Network
Network status blink occurs up to 50 times. Single button press will resume status blink for another 50 cycles.
About LoRaWAN
LoRaWAN is a low-power, secure, wide area (LPWAN) networking protocol designed to wirelessly connect devices to the internet in regional, national, or global networks. To use the CS1010 Leak Sensor, wireless connectivity to an internet connected LoRaWAN gateway is required.
For more information about LoRa and LoRaWAN visit the LoRa Alliance webpage: https://lora-alliance.org/.
Terminology
- Message sent from the Leak Sensor to the network are referred to as “uplink messages” or “uplinks”.
- Messages sent to the Leak Sensor from the network are referred to as “downlink messages” or “downlinks”.
- Both uplink and downlink messages may be of either “confirmed” or “unconfirmed” type. Confirmed messages are guaranteed to be delivered but will consume extra wireless bandwidth and battery life. These mechanisms are analogous to TCP (confirmed) vs UDP (unconfirmed) protocols used for IP networks.
- Before a device, such as the CS1010 Leak Sensor can transmit messages using LoRaWAN it must go through a “join” process. The Join process involves key-exchange with the cloud-hosted network provider (The Things Network, Helium, etc.) and is defined in the LoRaWAN protocol standard. If connectivity is lost due to RF interference, power loss or other temporary internet outages, the device will need to rejoin the network prior to being able to transmit messages. This process happens automatically but is managed in a battery-efficient manner and may take significant time.
Installation
Place the leak sensor where a leak or flooding may occur.
Suggested Applications
- Basement Floors
- Under Laundry Machines
- Under Dishwashers
- Under Refrigerators (w/Ice Machines)
- Near Sump Pumps
- Under Fish Tanks / Aquariums
- Inside Hot Tubs*
- Locations Subject to Freezing Pipes*
*Please refer to device environmental operating range information. Use this device outside at your own risk.
Event Notifications and Reports
The CS1010 Leak Sensor has three event notifications:
- Leak Detected – Sensor has detected a leak (default enabled).
- Leak Cleared – Sensor no longer detects a leak (default enabled).
- Leak Detected Reminder – Periodic reminder that a leak is ongoing and has not been cleared. This notification is not enabled by default and can be configured by the application.
Additionally, statistics can be enabled to report aggregate sensor event activity:
- Leak Detect Counter
- Leak Clear Counter
- Lifetime Leak Detect Time
- Lifetime Leak Clear Time
- Min/Max Leak Detect Duration
- Min/Max Leak Clear Duration
Statistics are stored in non-volatile memory and will persist through a battery change or dead battery. Both the statistic reporting and alarms can be configured remotely by sending downlink messages.
The sensor has a periodic Heartbeat/ Battery-status message that is sent to maintain LoRaWAN network connectivity and indicate battery status information. The default period for this message is 60 minutes and may be configured between two (2) minutes minimum and 48 hours maximum
Reset Notifications
FACTORY RESET uplink messages will be sent after rebooting.
Firmware Version
The firmware information can be retrieved via sending a downlink command. See Configuration and Integration for details.
Replacing the Batteries
A small Philips screwdriver and tweezers are needed to replace the batteries.
|
- TO MAINTAIN THE WATERTIGHT DESIGN OF THE LEAK SENSOR, USE EXTREME CARE AND FOLLOW THE BATTERY REPLACEMENT INSTRUCTIONS CLOSELY.
- DO NOT MIX OLD AND NEW BATTERIES
- MAKE SURE THE BOTTOM SHELL AND SEALED RUBBER PADS ARE TIGHTLY
SECURED. OTHERWISE, THE ENTRY OF WATER INTO THE SENSOR MAY CAUSE SEVERE DAMAGE.
