We recommend using GSM, WiFi, or ethernet connector devices / sensors hubs with any Industrial IoT sensors since they're much more reliable than Androids for Industrial IoT applications like:
- Natural resources
- Chemical cleaning companies
- Oil & gas
- Industrial cleaning services
- Water resources management
- Chemical distribution
- Fluids monitoring
You can use Valarm Industrial IoT, telemetry and remote sensor monitoring solutions with any of the following connector devices:
- GSM Sensor Hub
- WiFi Sensor Hub
- Ethernet Sensor Hub
- Valarm Industrial IoT sensor data is GPS location-tagged, time-stamped, and sent to Valarm Tools Cloud / tools.valarm.net via any internet connectivity like WiFi, ethernet, or cell network. With Valarm Tools Cloud you’ll find services for mapping, graphing, and APIs like JSON to help you with your real-time, geo-enabled sensor monitoring and Industrial IoT applications.
- Is your basement flooding or water heater leaking?
- Do you want to keep track of the water level in your swimming pool, rainwater reservoir or personal fishing pond?
- How much water or liquid nutrient is remaining in the container for your plants?
In this How To tutorial we’ll teach you how to do water detection with an Android device and a Yocto-Knob sensor.
First, get the Valarm Pro app on your device from the Google Play store. We recommend using a dedicated device (Android devices are more affordable every day) for applications like this.
Next, in Valarm Pro go to the Yoctopuce settings screen to set up your Yocto-Knob electrical resistance sensor for water detection.
Step 1: Connect Wires and Leads to Sensor
Each lead provides you with a threshold for the water level that is important for you. For example, with 5 wires you could put each one an inch apart and have Valarm alert you via text message or email if any of the wires are triggered.
Now based on which wire is triggered you will know how high the water is, e.g., 1, 3, or 5 inches.
Step 2: Calibrate the Sensor
Step 3: Set Up Your Water Detection / Flood Alert Environment
In this example we’ve used a French Press (also makes great coffee and tea!) to demonstrate Valarm’s ability to alert you to different heights and water levels.
Set up each wire in your scenario to your desired level.
Step 4: Confirm Sensor Settings
Use the Scan All button to see what kinds of measurements you get with your wires in and out of the water.
Here we found that values above 500 occur when the wire is submerged. So we set the max to 500 meaning Valarm will trigger alerts when water reaches this sensor wire.
Step 5: Configure Your Alerts: Text Messages (SMS), Email, Web Maps, Graphs
Remotely control your device and sensor by text message.
Post all of your data to the web at tools.valarm.net for visualization, data export/download, and analysis.
The screenshot above shows a water level trigger being uploaded to tools.valarm.net and an alert being sent out via email.
Step 6: Monitor Anything, Anywhere
Check out the Valarm blog for other use cases such as Valarm for remote home monitoring or Valarm with a laser pen and light sensor for intruder detection. Try out Valarm for a variety of things like hydroponics and aquaponics!
Use any combination of sensors, e.g., temperature, pressure, humidity, CO2, volatile organic compounds (VOCs). Here is a list of compatible sensors you can use.
