Essential Info

The Nitro Networks HWA-501M HiWATER Alert is an electronic device that detects when water is present at the end of sensor wires. This triggers the HiWATER Alert to transmit an email or text message via your wireless or wired internet connection. As long as water is present, the alert is repeated at pre-determined intervals. Upon detecting a drop in the water level, the HiWATER Alert transmits an "All Clear" message to your phone or email. The unit is powered by an AC adapter (included).

    Easy setup. I can set up the device to give me an update on temperature in the basement on daily basis - this also helps me to confirm that the device is working. When water is sensed, the devices emails and texts me. The one downside is when water is sensed, the alarm is so soft that you cannot hear it unless you are in the basement. It's more reliable to get the alert from your smartphone.

    Easy setup with D-Link wireless router. Easy to setup warning thru texting and email. No monthly fee or any other fee. The downside is that the alarm beep is not loud at all. Count on hearing the warning through your phone instead of the alarm itself. There is no way I can hear that beep coming from my basement!
