Main highlights

Multiple Notifications: Receive alerts via email and text message for high or low water levels, water level returning to normal, low battery, and device offline (WiFi connection lost). Compared to similar products from some other brands, which only provide alerts for high or low water levels, our product is much more intelligent.

Enhanced Alert Reliability: Risinglink allows you to register 2 phone numbers and 4 email addresses per device. Be cautious of competitors claiming to support multiple phones; some restrict direct text alerts to only one phone number, relying on unreliable Email-to-SMS services for the 2nd phone. Others depend entirely on Email-to-SMS for all alerts. If you and an additional contact, such as a spouse or coworker, need timely and reliable text alerts, Risinglink is the right choice for you!

Easy Setup: No need for apps or hubs, simply connect the device to your WiFi network(Note: only 2.4GHz WiFi supported). No monthly fees or subscription costs.

Two relay outputs control: Normally Relay output 1(terminal 7.8) connects with water pumps, used for controlling water pump on/off. Relay output 2 ( terminal 9.10 ) is used for Anti water dry heating protection.

Real-Time Supervision: APP can display the current water level. There are five water levels: 0%, 25%, 50%, 75%, 100%. Water level rising: water level < 25% electrode; App display 0%; reach to 25%, App display 25%; reach to 50% , App display 50%; reach to 100%, App display 100%. Water level reducing: Water level below 100%, App display 75%; below 75%, App show 50%; below 50%, App display 25%, below 25%, App display 0%.

It is a type of WIFI intelligent water level controller, which can be set by APP to realize water level monitoring, Water supplement or drainage, high and low water level remote APP push alarm notification etc,. The product is suitable for various water level control occasions, such as HVAC system, hot water process, municipal drainage, boiler, water tower, storage tank, breeding irrigation etc.

Main highlights

The principle is to use the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the existence of distributed capacitance on the sensor. When the liquid level slowly rises and approaches In the case of an inductor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the final capacitance value of the inductor larger.

The changed capacitance signal is then input to the control IC for signal conversion, which converts the changed capacitance into a change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain amount It is considered that the liquid level has reached the sensing point when the threshold is reached.

The CQRobot non-contact liquid level sensor realizes non-contact detection of the liquid level in a closed container. It adopts advanced signal processing technology and high-speed signal processing chip, breaking through the influence of container wall thickness. It is simple to install and easy to use, and can detect the level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers.

【RECEIVE ALERTS EVEN WHEN YOU ARE NOT AT HOME】- Our smart devices can be connected to cell phones and iPad via WiFi (2.4G ONLY). After successful connection, when there is a water alarm, as long as the cell phone network is normal, no matter where you are, you can receive a push alert from the app（FREE). 𝙎𝙈𝙎/𝙥𝙝𝙤𝙣𝙚 𝙘𝙖𝙡𝙡 𝙞𝙨 𝙖 𝙥𝙖𝙞𝙙 𝙨𝙚𝙧𝙫𝙞𝙘𝙚, 𝙮𝙤𝙪 𝙘𝙝𝙤𝙤𝙨𝙚 𝙬𝙝𝙚𝙩𝙝𝙚𝙧 𝙩𝙤 𝙤𝙥𝙚𝙣 𝙞𝙩 𝙤𝙧 𝙣𝙤𝙩?

【EXCLUSIVE DESIGN AND TECHNICAL INVENTION】- The first 2-in-1 separated dual probe structure, which can meet the needs of almost all water level detection scenarios. It can detect two modes (High/Low) at the same time, the left and right probes can be quickly distinguished by different sounds, and the left and right alarms can also be quickly distinguished by APP alerts.

【100 DB LOUD ALARM SOUND】 - When there is no network, if the detector detects a dangerous situation, it will also send out a 100 dB sound to alert at the first time. If it is not handled, it will sound the alarm again every 10 minutes. In addition, the sound can adjustable: HIGH - MEDIUM- LOW - MUTE, Quickly double-click the button to adjust. 【NOTE: In MUTE mode, If the WiFi is normal, the APP will receive push notifications as usual】

WARM REMINDER: The testing requirements must satisfy the following two points simultaneously: 1. We suggest installing the sensor in the middle of the water tank. The sensor's readings may be impacted when it touches the water surface. Ensure it stays dry during calibration. 2. The length of the water tank should be twice the height of the tank. Please ensure before purchasing that our product is suitable for the size of your water tank

MONITOR WATER TANK LEVEL: The Briidea micro monitor system is specifically designed to monitor the water level in your RV's fresh water tank, allowing you to top up the tank in a timely manner and avoid situations where the tank runs empty. The kit includes all the necessary materials, so you won't need to purchase additional sensing electrodes, saving you time and money. Friendly reminder: Some metal water tanks may affect detection accuracy
