Working principle of rain gauge-Rainfall calculation-RS-100 optical rain gauge-Tianxing Zhilian rain gauge manufacturer-Product description
The rain gauge RS-100 optical rain sensor uses the principle of optical induction to measure rainfall, has multiple built-in optical probes, and uses reliable remote control
Measurement method to ensure reliable detection of rainfall. Different from traditional mechanical sensors, optical rain is smaller, more sensitive, more reliable, more intelligent and easier
Maintenance supports boot calibration and installation error reminders, and supports switching and UART output.

How the rain gauge works – Rainfall calculation – RS-100 optical rain sensor – Frequently asked questions
Q: How does the product work?
A: Infrared light sensing principle.
Q: What signal does the rain module output?
Answer: It can output switching signal, 5V pulse signal, UART signal.
Q: How about the accuracy?
A: The accuracy of our sensors can reach ±5.
Q: Can I connect the signal of the relay to the PLC?
Answer: The output of the sensor is the switch signal of the relay, which can be connected to the switch signal interface on the PLC.
Q: What does a signal from a sensor represent?
Answer: One signal represents 0.1mm in rain measurement mode, and one signal represents rain in rain sensing mode.
Q: What is the level of protection?
A: The protection level of the sensor can reach IP66.
Q: If there is dust on the surface of the probe for a long time, is the sensor inaccurate?
A: The sensor detects that raindrops are sliding on the surface of the probe, and the dust on the surface has little effect on the probe.
Q: What are the advantages of your sensors compared to traditional rain gauge barrels?
Answer: The traditional rain bucket is large in size, and the installation needs to be made of cement foundation, and the drainage outlet is easy to be blocked, and someone needs to maintain it regularly.
Our sensors are small, easy to install, and have low maintenance costs.
