KONLENTuya Smart Home Water Level Sensor WiFi Controller Leakage Flood Alarm Swimming Pool Pump Tank Flow Detector
Main highlights- Water level upper and lower limit Alarm, real-time push alarm notification to users' smartphone.
- Two working mode: Preset"Add water" or "Pump water" working mode, can auto turn on/off relay 1 when it reaches to the preset water level value.
- 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.

CQRobotCQRobot Non-Contact Water/Liquid Level Sensor Compatible with Arduino, Raspberry Pi and Other Motherboards. for Industrial Production, Aquarium, Chemical Solution, Agriculture, Gardening, etc.
Main highlights- The sensor comes with 2 DIP switches, the right DIP switch controls the output voltage (high level) of the signal terminal (green line); when the DIP switch is dialed up, the high level is 5V; when the DIP switch is facing When dialing down, the high level is 3.3V. Compatible with Arduino, Raspberry Pi and Other Motherboards.
- 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.
- High stability, high sensitivity, strong interference ability, no external electromagnetic interference, special treatment for power frequency interference and common mode interference, strong compatibility, penetration of various non-metallic containers, such as plastic, glass, For ceramics and other containers, the sensing distance can reach more than 12mm; liquid, powder, and particulate matter can be detected.
