【Dual 5 Meter Floating Probe Design】- It can detect water shortage or overflow. You can choose to use one or both functions according to your needs. The overflow probe is placed above the water level. When the water level rises to the detection position, the float will rise and trigger the magnetic induction, thus triggering the alarm. Instead, the water shortage probe is always placed in the underwater position, which triggers an alarm when the water level drops below the float.

【120 dB with Red Light Strobe Alarm - Volume Adjustable】- The volume of the water alarm can be adjusted according to the installation distance, and the alarm can also be used as a home safety alarm. You can DIY yourself, the alarm will be triggered when the two wires on the probe are shorted.

【Extendable Detection Line】- The detection line of this water detector can be extended to 164ft to meet the needs of your family. Please use good quality copper core extension wire.

【Low Power Design】- 9V replaceable battery power supply, standby for more than 1 year. When the battery power is low, the water sensor sound will become small or there is no alarm sound. Please replace the battery at this time.

【Wide Range of Uses】- This dual probe water level detection alarm can be used in many scenes, such as solar water tank, fish tank, swimming pool, basement, warehouse, bathroom, kitchen, laundry, etc. In addition, this high decibel alarm can also be connected with other sensors to become a home safety alarm system

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.

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.

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.

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.

CQRobot Non-Contact Water/Liquid Level Sensor Compatible with Arduino, Raspberry Pi and Other Motherboards. for Industrial Production, Aquarium, Chemical Liquid, Agriculture, Gardening, etc.

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.

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!

Durable Construction: The stainless steel float sensor offers superior reliability and durability compared to plastic alternatives, and it features a 10-foot long cable for added convenience.

Effortless Installation: Easy to install the stainless steel float sensor. With its own weight, just hang the float sensor without the need for a mounting bracket.

Outdoor-Ready: The main controller is designed for outdoor use with an IP65 waterproof rating, ensuring durability and protection from the elements.
