L106 Drop Sensing Rain Sensor
Product Introduction
L106Drip sensing rain sensor adopts a new drop sensing design concept, and its internal structure is designed with a special structure to accurately control the size of raindrops,Then use the principle of optical induction to count raindrops,Thus measuring the magnitude of rainfall.
It is different from traditional tipping bucket, pressure sensing or optical rain sensors. It combines the advantages of these three principles, overcomes their disadvantages, and truly achieves both compact size and accurate measurement.
It can be widely applied in industries and fields such as smart agriculture, meteorological environmental protection, smart irrigation, ship navigation, water conservancy and hydrology, urban waterlogging, geological disasters, etc.
Features
Small size, light weight, and easy installation.
Diameter 7.5CM, height less than 9CM, very easy to integrate with other sensors.
High reliability, capable of working normally in high temperature and high humidity environments.
No moving parts, not easily worn out, easy to maintain.
The brand new droplet sensing design principle ensures accurate measurement and complies with national standards.
Made of metal material, sturdy and durable, with a grand appearance.

Experimental testing methods
If the customer wants to verify the accuracy of the sensor through a simple method, they can operate it as follows: wet the product's water receiving port, then turn on the power, and pour in no more than 11.3ml of water evenly within 1 minute, and the water needs to be dripped in droplets, because when the maximum rainfall intensity exceeds 4mm/At min, the measurement data may not be accurate. (4mm/min range according to national standards).
Calculation method:For example, if 2ML of water is slowly poured into the device within 1 minute, the current rainfall intensity calculation method is RS=2000/(30 * 30 * 3.14) mm.
Note: 2ml of water equals 2000 cubic millimeters of water, and the radius of the rainwater outlet is 30mm.
Precautions
1. Please check if the packaging is intact and verify if the product model matches the selected one; Do not connect live wires. Only after the wiring is checked and confirmed to be correct, can the power be turned on;
2. The length of the sensor wire will affect the output signal of the product,Do not arbitrarily modify the components or wires that have been welded before leaving the factory when using the productIf there are any change requirements, please contact the manufacturer;
3. Sensors should be regularly inspected to remove dust, mud, leaves, and insects to avoid blocking the water flow channel of the upper tube (funnel),Long term work usually requires cleaning once a month, and cleaning must be done once every three months;
4. If there is dirt on the inner wall of the tipping bucket, it can be washed with water or detergent solution. It is strictly prohibited to wipe with fingers or other objects to avoid oil stains or scratches on the inner wall;
5. During the winter icing period, the instrument should be stopped from use and can be retrieved indoors;
6. Please keeppipegoodWarranty CardReturned together with the product during maintenance.
Warning for use
Do not use rain sensors in any location where serious consequences may arise from incorrect sensor readings. It is the responsibility of the system designer or system integrator to ensure fault tolerance and prevent catastrophic consequences caused by an error in a component, including a rain sensor. Our company does not assume any responsibility for any consequences caused by sensor indication errors.
troubleshooting
1simulationSignal orRS232,RS485When outputtingThe instrument display value is incorrect.Possible wiring issuesOr communication serial port failureresult in failureObtain accurate dataPlease check if the wiring is correct and secureIs the serial port occupied and is the serial port setting correct;
2The displayed value on the monitor clearly does not match the actual situation. Please clean the sensor water tank, funnel, etc., and then test according to the experimental testing method;
3If it is not for the above reasons, please contact the manufacturer.
