- Would you like to know how much water is in your reservoir?
- How much water is flowing through your customer’s pipes?
- Is your basement flooding, water heater or something else 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?

Here’s the old tutorial from our legacy app below. However, see above for how we recommend you do it today with dedicated sensor hubs connected to Tools.Valarm.net. 1. First, to use an Android device for water detection, get Valarm on your device from the Google Play store. We recommend using a dedicated device (Android devices like the Sony Xperia U ST25 are getting cheaper every day!) for applications like this.
2. Next, in the Valarm app go to the Yoctopuce settings screen to set up your Yocto-Knob electrical resistance sensor for water detection.
3. Connect a wire to the ground as well as however many of the Yocto-Knob lead wires you would like to use (up to 5). 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. Then based on which wire is triggered you will know how high the water is, e.g., 1, 3, or 5 inches.
4. Now we will calibrate each of the channels. Tap the calibration button then begin calibrating. While you are calibrating Valarm, submerge the ground wire in a water source (tea and coffee cup used in the example image above) and dip the lead you are calibrating into the water. Take the lead out of the water while still calibrating and dip it in a few more times to calibrate Valarm and the Yocto-Knob for a reasonable threshold. Do this for as many channels (up to 5) as you would like to use. If you just want to know if water is present and not measure specific heights then you will only need to calibrate one channel.
5. With Valarm and Yocto-Knob calibrated we can set up our water detection scenario. 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.
6. For water detection, use the Inverted Min/Max option for each Yocto-Knob channel since we will get an increased resistance measurement when water has reached each level. 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.
7. Set up your Valarm alerts to send out text messages (SMS) and/or email messages whenever a certain water height is triggered. Post all of your data to the web at tools.valarm.net for visualization, data export/download, and analysis.
